Isabella grapes: all about cultivating varieties, crop care recommendations
Isabella is one of the most common grape varieties in the world. By appointment, it is a canteen, that is, universal. It can be consumed fresh, make wine, cook stewed fruit, jam, jelly and so on. This variety is popular with gardeners due to the general lack of care, high yield, low calorie content, and the ability to withstand most of the diseases typical of the culture.
Description of Isabella Grapes
Isabella (the official name isabella Banska) is a grape variety that appeared spontaneously as a result of natural selection. According to most botanists, this happened as a result of pollination of the noble European vine Vitis Vinifera with the local Vitis Lambrusca. Attempts to grow familiar elite grapes on the new continent have been made repeatedly.
Isabella grapes - one of the old well-deserved varieties, so far not lost popularity
Isabella has been known to gardeners since the 19th century. This grape was first discovered in the United States by breeder William Prince in 1816 in one of New York’s gardens on Long Island. By the way, later it was he who bred Isabella Rozovaya, which is better known as Lydia in Russia and the CIS countries. In honor of the wife of the land owner, George Gibbs, Isabella was named. Most often, South Carolina is called its homeland (even a specific place is mentioned - Dorchester), but there is another point of view according to which this grape “came” to New York from Virginia or Delaware.
Isabella came to Russia (then the USSR) relatively recently, only in the 50s of the last century. But this variety was quickly appreciated by winemakers. Now it is distributed in Georgia, Moldavia, Azerbaijan, Armenia, and Ukraine. In Russia, it can be grown not only in the warm southern regions, but also in the Moscow region and the Volga region. The “native” climate for Isabella is temperate, bordering on the subtropical. Therefore, it tolerates cold, which is detrimental to many other grape varieties.
Isabella belongs to the category of universal varieties. Grapes can be used for the production of wine, and for eating, as well as raw materials for all kinds of homemade blanks. The variety is late, the growing season is 5–6 months.

Young Isabella vines do not differ at a particular growth rate, but plants older than ten years can add up to 3.5–4 m in length annually. Stepson formed a little. The shoots of young plants are greenish, with raspberry shimmer and thick edge. Then they change color to brown-gray. Leaves are not too large, consisting of three parts or whole. The front side is saturated dark green, the inside is grayish-white.
Isabella's leaves, unlike many other grape varieties, are not very dissected
Brushes of medium size, weighing about 180-250 g, are not very dense. But the yield is high due to the fact that 2-3 brushes are formed on each fruiting shoot. In shape, they resemble a cylinder or an inverted cone. If the weather turned out to be successful in the summer, with proper care, brushes weighing 2–2.5 kg can be grown. In general, the more clusters, the less the mass of each of them. On average, 50-60 kg of grapes are harvested from an adult vine.
Isabella grapes are not too large, but yields do not suffer.
The berries are almost spherical (1.7–2 cm in diameter), black-violet with a thick bloom of gray-gray color. The skin is very dense, durable. Thanks to this feature, Isabella is notable for good transportability. Sugar content at the level of 16–18%. The average weight of the berry is 2.5–3 g. The flesh is sweet and sour, slimy, pale green or greenish-yellow in color, with an easily recognizable flavor resembling garden strawberries. There are few seeds in the berries.

Harvest ripens very late in the first decade of October. To understand that the berries have ripened is very easy by the “nutmeg” aroma distributed by them. The first fruiting can be expected in 3-4 years after the planting of a grape seedling in the ground.
Isabella grapes stably pleases the gardener with high productivity
For over a century, Isabella has remained one of the most popular grape varieties not only in the homeland, in the USA, but also in Europe. Having a few vines for the winemaker was considered a tribute to tradition and a sign of good taste. However, in the middle of the 20th century, evidence appeared that during its fermentation toxic substances are produced, including methyl alcohol (80–120 mg / l compared with the norm of 30–40 mg / l), formic acid, formaldehyde. This is due to the high content of pectins in the skin. They can cause serious harm to health, up to the development of liver cirrhosis, multiple sclerosis, chronic kidney diseases, problems with the optic nerve. This feature does not apply to juices and other harvesting from fresh grapes. Therefore, it was forbidden by law to use Isabella for winemaking, which entailed a significant reduction in the area allocated for it.
Even the barren Isabella can find use in the garden
In fairness, it should be noted that subsequently this information was not confirmed. But Isabella’s reputation, declared a “relic of the past, ” was significantly damaged. In addition, in other alcoholic beverages (cognac, vodka, brandy, whiskey), the methanol content is significantly higher. But no one has repealed laws yet. Therefore, one can partly consider the point of view according to which all the hype raised was due to protectionism and unwillingness to create competition for European wines in the form of products from the Americas, Australia, because local varieties serve as raw materials for it.
Isabella's health benefits have been scientifically proven. Its berries, in comparison with other grape varieties, are characterized by a high content of phytoncides, therefore, the juice obtained from them has pronounced antibacterial properties. There are many antioxidants in them that slow down the aging process. But due to the high content of fruit acids, undiluted juice is not recommended for use in the presence of diseases of the gastrointestinal tract. Isabella also has a lot of potassium, which prevents the elimination of fluid from the body. Eating it is not recommended for kidney problems and a tendency to edema.

Advantages and disadvantages of the variety
The undeniable advantages of Isabella grapes include:
- general unpretentiousness. The Isabella variety is undemanding to fertilizing, soil quality, has good immunity. Even a novice gardener will cope with its cultivation;
- high frost resistance for grapes. Isabella without much damage to herself suffers cold to -32-35ºС in the presence of shelter. Without it - up to -25–28ºС. This allows us to grow such grapes not only in Moldova, Ukraine, the south of Russia, but also in regions less suitable for this culture, for example, in the Moscow Region, even without winter shelter. If Isabella comes under spring return frosts, new shoots in the place of the victims are formed after 2-3 weeks and have time to fully form this season;
- the presence of immunity against diseases typical of culture. Isabella is extremely rarely affected by such fungal diseases as mildew, oidium, powdery mildew, gray rot, almost does not suffer from phylloxera. The disease does not extend to its vines, even if it affects the growing nearby varieties;
- ability to tolerate waterlogging of the soil well. Many grape varieties develop rot as a result of frequent and / or heavy watering;
- ease of reproduction. Cuttings are very easy to take root, care for them is minimal;
- universality of purpose. The taste unloved by European winemakers is considered quite acceptable in Russia, the USA, Australia, South America, and other countries. Yes, you cannot name high-quality wine from Isabella, but most people who do not understand the intricacies of the bouquet of this drink. Many people like it. But “juicy” aroma gives juices, compotes, and other home-made preparations a light piquancy;
- low calorie content (only 65 kcal per 100 g). For grapes, this is, in principle, very atypical. Isabella can very well be consumed in order to diversify the diet. Also, despite the rich color of the skin, this variety rarely causes allergies;
- decorative value. Even if the climate does not allow you to get a grape harvest, Isabella can be used in landscape design for landscaping the garden. She looks very impressive, entwining an arbor, a veranda, a fence. In autumn, the leaves acquire a very beautiful golden yellow hue.
Isabella is not least appreciated for its unpretentiousness and ability to stably and abundantly bear fruit in not the most ideal climatic and weather conditions.
The variety also has some disadvantages:
- Isabella reacts very negatively even to short droughts. This does not have a positive effect on productivity. Therefore, watering grapes need to be given special attention. Otherwise, the vine may partially or completely discard leaves and brushes. Those berries that still ripen, are very small and acquire a tart aftertaste.
- The variety is sensitive to the high content of lime in the soil. Hydrated lime for deoxidation of the soil is strongly discouraged. Dolomite flour, sifted wood ash, and egg shells crushed into powder can be added to the bed. Isabella does not like acidic soil, so it is advisable to find out the acid-base balance in advance.
- The tendency to lose anthracnose. Its prevention must be carried out annually, in spring and autumn.
- The presence of a characteristic taste, professional winemakers called fox, which gives the berries specific essential oils and acetophenone contained in the skin. It remotely resembles garden strawberries, but not real, but artificial flavor. For winemaking, this is considered a very serious drawback (it is typical for all American varieties and hybrids), causing the appearance of an unpleasant putrefactive smell in a bouquet of wine, noticeable even to lay people, after only three years of storage.
Specialists rate wine from Isabella not too high, but many amateur wine-makers like it very much.
How to plant grapes
The time for planting Isabella seedlings in the soil depends on the climate. In the warm southern regions, the procedure is most often planned at the beginning or middle of September. In a subtropical climate, you can be sure that at least 2.5 months are left before the first frost. During this time, the seedling will have time to acclimatize in a new place.
Landing in spring is the only option for temperate regions. There, winter often comes unexpectedly and not always in accordance with the calendar. And during the summer, grapes planted at the end of May will take root and recover from the stress associated with changing living conditions.
Isabella is not very demanding on soil quality, successfully adapting to both sandy and clay substrates. But the best option for her is fertile, slightly acidic soil. When choosing a place, it should be borne in mind that the vine should be well ventilated (but not subject to regular exposure to sudden gusts of cold wind). Therefore, do not plant grapes next to a solid wall, a fence. The trellis is positioned so that the vines "look" to the south or west. The best place for it is a small hill or a gentle slope.
Isabella should not be planted closer than 5-6 m from any fruit trees. The vine can simply "strangle" their roots, depriving them of food. Especially grapes for some reason do not like apple trees.
In addition to alkaline soil, a salted substrate is not suitable for Isabella. It also negatively relates to close (1.5 m from the soil surface and less) located groundwater. For the same reason, lowlands do not fit - there for a long time stagnates water and damp cold air.
Before planting, the roots of the grape seedling are carefully inspected, all dead and dried parts are cut, the rest is shortened so that they absorb water and nutrients better
Isabella's annual seedlings take root best. The correct plant has at least 20 cm in height and 3-4 roots 10-15 cm long. The bark of the seedling should be clean and uniform, without mechanical damage and stains, reminiscent of traces left by mold and rot. The roots in the section of healthy seedlings are white, the shoots are greenish. You need to purchase planting material in a nursery or a trustworthy private farm. Otherwise, there is no guarantee that you will buy exactly what you need.
High-quality planting material is the key to a plentiful harvest in the future
The landing pit should be large enough - about 80 cm in depth and the same in diameter. The root system of the grapes is developed, the roots go into the soil for 4–5 m. It is always prepared in advance - in the fall, if planting is planned for the spring, and at least 2-3 weeks, if in the fall. At the bottom, a drainage layer with a thickness of at least 5–7 cm is required. Crushed stone, pebbles, expanded clay, ceramic shards, and other suitable materials can be used. Fertile turf mixed with humus (15–20 l), sifted wood ash (2.5–3 l) is poured on top. The thickness of this layer is about 10 cm. Natural fertilizer can be replaced with potassium sulfate (50–70 g) and simple superphosphate (120–150 g). Sprinkle fertilizer with earth (about 5 cm), and repeat again. As a result, a “pie” is formed of five layers: drainage, nutrient soil, ordinary earth (the latter - two each). It is watered, consuming 80-100 liters of water.
The landing pit for Isabella should be deep, a drainage layer is mandatory at the bottom
The landing procedure itself looks like this:
- A day before the procedure, cut the roots of the seedling by 3-5 cm and soak in water at room temperature. You can add potassium permanganate crystals to it to a pinkish color (for disinfection) or any biostimulant (to increase immunity). Suitable store products (Epin, Zircon, Heteroauxin), and natural (aloe juice, succinic acid).
- Immediately before planting, dip the roots into a mixture of powdered clay and fresh cow manure, reminiscent of thick sour cream in consistency. The mass must be allowed to dry. This usually takes 2-3 hours.
- To establish a peg in the center of the planting pit - a support for a seedling approximately 20–25 cm higher than a plant. Near it, form a small mound from the remaining after the pit was excavated, the earth. Pour abundantly (20–25 L) and wait until the water is absorbed. You can also dig into the pit a piece of a small diameter plastic pipe for watering, but Isabella, unlike many grape varieties, can be watered in the usual way.
- Place the seedling on the knoll, gently straightening the roots. Fill the hole with soil, periodically compacting it, so that a 5-7 cm recess is formed. Take care not to deepen the place where the branching of the shoots begins. It should rise 3-4 cm above the soil surface. Saplings 25-30 cm high are planted vertically, the rest - at an angle of about 45º.
- Trim existing shoots by shortening them by 15–20 cm (upper 5–6 growth buds). Securely fix the seedling by tying it to a support.
- Once again, pour grapes abundantly (40-50 l). When the moisture is absorbed, mulch the trunk circle with peat crumb, humus, freshly cut grass.
- Cover the seedling with a cut-off plastic bottle for 2-3 weeks. To protect from direct sunlight, cover with a canopy of any white covering material.
Landing Isabella in the ground is a simple procedure, even a beginner gardener will cope with it
When planting several seedlings, a minimum of 1.5 m is left between them. The distance between the rows is 2.5–3 m. When planting is thickened, the vines do not have enough space for food, the yield is greatly reduced. You also need to provide space for trellis. The simplest option is several rows of strong wire stretched between supports at a height of about 80, 120, 170 cm. If an entire plantation is laid, you can dig a continuous trench instead of individual holes.
The root system of grapes is developed, so each plant needs enough space for nutrition

Crop Care Tips
One of the main advantages of Isabella grapes is their general unpretentiousness. However, it is impossible to receive regularly without minimal care.
Grapes are a moisture-loving plant, but this only applies to young vines under the age of two years. Adult bushes require significantly less water; its excess is even harmful to them. If the soil is clay, Isabella is rarely watered, but abundantly. On the contrary, vines growing in sandy soil require frequent, but moderate watering. Once a month, it is advisable to replace ordinary water with an infusion of fresh cow manure diluted with water in a proportion of 1:10.
Young non-fruiting grape seedlings need abundant watering
Young plants are watered every week, spending 15-20 liters of water. Adults need the same rate every 2–2.5 weeks. They definitely need to moisten the soil when leaf buds swell and immediately after flowering. The best time for the procedure is the evening after sunset.
Starting from the end of August, as soon as the berries begin to acquire a characteristic shade of the variety, watering is completely stopped so that the brushes ripen normally. In the fall, if it is dry and warm, a couple of weeks after the harvest, the so-called moisture-charging irrigation is carried out, spending 70–80 liters per plant.
Watering grapes according to the rules requires the construction of fairly complex structures, but when growing Isabella, you can do with the usual grooves between rows of plantings
When watering, it is very important that drops of water do not fall on the leaves. This also applies to rain, so it is advisable to build a canopy over the trellis. The best way is to moisten the soil with special pipes or drip irrigation. In the absence of technical feasibility, water is poured into trenches dug between the rows of vines or the circumferential grooves surrounding them.
After each watering, the soil must be mulched. Mulch helps retain moisture in it, does not allow the soil to quickly dry out. For Isabella, this is especially true, this grape variety does not like drought. About half an hour after the procedure, the soil is loosened to improve aeration of the roots.
Isabella grapes are enough three feedings per year. Additionally, every 2-3 years, depending on the fertility of the soil, in the spring natural organic matter (humus, rotted compost) is added to the soil at the rate of 15–20 l per plant.
A well-developed root system of grapes pulls a lot of nutrients out of the ground, therefore, soil fertility must be maintained.
The first top dressing is carried out in the spring, as soon as the soil has thawed sufficiently. It is especially important in regions with an arid climate. Isabella is watered with a solution of any nitrogen-containing fertilizer - urea, ammonium nitrate, ammonium sulfate (1.5–2 g / l). In addition, 10-12 days before flowering, it is useful for Isabella to pour infusion of bird droppings, nettle leaves or dandelion.
Urea, like other nitrogen-containing fertilizers, stimulates grapes to intensively build green mass
The second time fertilizers are applied when the fruits are tied. В это время растению нужен калий и фосфор. Простой суперфосфат (35–40 г), сульфат калия или калимагнезию (20–25 г) растворяют в 10 л воды. Альтернатива — настой древесной золы (литровая банка на 3 л кипятка).Recent entries In April, I process roses so that no pests encroach on my beauties

Последняя подкормка — комплексное удобрение для винограда. Наиболее популярные препараты — Экоплант, Растворин, Кемира-Люкс, Новоферт, Флоровит, Мастер. Раствор готовится согласно инструкции производителя.
Комплексные удобрения, внесённые осенью, помогают растению правильно подготовиться к зиме
Как и любой виноград, Изабелла чувствительна к дефициту магния. Чтобы этого избежать, растения 2–3 раза за сезон опрыскивают раствором сульфата магния (20–25 г/л).
Видео: типичные ошибки садовода, начавшего выращивать виноград
Взрослые лозы Изабеллы отличаются сильнорослостью, поэтому обрезка для этого сорта винограда — обязательная процедура. Главная её цель — заставить куст разрастаться вширь, а не в высоту. Основную обрезку проводят осенью. Весной «пострадавшая» лоза обильно «плачет», выделяя много сока, который заливает «глазки». Из-за этого они не распускаются и могут загнить.
Обрезка винограда проводится только остро заточенным и продезинфицированным инструментом
Весной до точки роста удаляют все вымерзшие, сломанные, высохшие побеги. Осенью обрезку Изабеллы проводят во второй декаде октября, после окончания плодоношения. Обязательно срезают все повреждённые и слабые пасынки. Прирост этого сезона укорачивают примерно на треть, полностью одревесневшие побеги — на две трети. Каждую плодоносившую лозу укорачивают до 12 ростовых почек.
В течение лета удаляют неудачно расположенные листья, мешающие правильной аэрации винограда, побеги, растущие вниз и вглубь куста. Грозди прореживают так, чтобы каждая из них не касалась соседних. Чем их меньше, тем крупнее будет кисть и ягоды на ней. Норма для взрослого растения — не более 35 гроздей.
Виногдадные лозы подвязывают к шпалере так, чтобы не травмировать древесину
Формирование лозы начинают со второго сезона пребывания в открытом грунте. На молодой лозе оставляют не более 7–8 побегов. Их привязывают к шпалере, направляя горизонтально. Изгиб должен быть достаточно плавным, чтобы проводящая система не пострадала. Как только побеги дорастут до следующей горизонтальной проволоки, их фиксируют на ней. Привязывают лозу, подложив мягкую ткань или мочало, чтобы она не перетиралась.

В южных регионах с субтропическим климатом Изабелла в укрытии не нуждается, чего не скажешь о средней полосе России. Там погода отличается непредсказуемостью, зима может выдаться и достаточно мягкой, и аномально холодной.
В принципе, Изабелла относится к неукрывным сортам винограда, но в средней полосе России лучше перестраховаться и защитить его от вполне возможных суровых морозов
После окончания плодоношения лозы снимают с опоры и укладывают на землю. Если есть возможность, помещают в выкопанные рядом неглубокие траншеи. Затем их засыпают торфом, перегноем или закидывают хвойными ветками, палой листвой. Сверху затягивают несколькими слоями любого пропускающего воздух укрывного материала. Когда выпадет снег, лозы закидывают им, создавая сугроб высотой около 30 см. За зиму он неизбежно осядет, поэтому придётся несколько раз подновить конструкцию.
Молодые лозы Изабеллы, чтобы защитить от холода, можно поместить в выкопанные в грунте траншеи
Весной укрытие снимают не раньше, чем воздух прогреется до 5ºС. Если есть реальная угроза возвратных весенних заморозков, в укрывном материале сначала можно проделать несколько отверстий для вентиляции. Ещё за день-два до похолодания лозы можно опрыскать раствором Эпина. Защитный эффект длится около 10 дней.

Common Diseases and Pests
Виноград Изабелла отличается высоким иммунитетом, он крайне редко страдает от болезнетворных грибков, ему не опасен такой типичный для культуры вредитель, как филлоксера. Единственное исключение из правила — антракноз.
This disease manifests itself in the form of brick-colored spots with a dark brown border on young leaves (under the age of 25 days) and non-lignified shoots. Gradually, they grow, merge and turn into pressed “ulcers”, their surface crackes, begins to rot. The tissues in these places die off, holes form. If nothing is done, the leaves turn brown, dry, the shoots turn black and become fragile, the entire aerial part of the plant dies.
Anthracnose is the only fungal disease that can seriously affect Isabella grapes.
For prevention, young shoots of grapes, reaching a height of 10 cm, are sprayed with a 1% solution of Bordeaux liquid or copper sulphate. The treatments are repeated throughout the growing season with a frequency of 12-15 days, using any modern fungicides - Topaz, Abiga-Peak, Skor, Horus, Ordan, Previkur, Ridomil Gold and so on. It is advisable to alternate drugs so that addiction does not develop.
Bordeaux liquid is one of the most popular fungicides, it is easy to purchase or make it yourself
Isabella rarely suffers from a massive invasion of pests. Almost everyone is effectively scared away by the sharp-smelling essential oils contained in the skin. For prevention in spring, blooming leaves can be treated with Nitrofen solution, and during the growing season, sprayed with a solution of salt and soda ash every 3-4 weeks (5-7 g / l).
But this feature is not an obstacle for birds. Therefore, to protect the crop, the vines are covered with a dense fine-mesh net. This is the only truly effective way of protection. Others (scarecrows, rattles, shiny and rustling ribbons, and so on) have the desired effect on birds for a maximum of several days. Birds very quickly realize that scary and dangerous-looking objects do no real harm to them and then do not pay any attention to them.
Robust mesh - the only reliable bird protection

Isabella to plant unambiguously! It does not freeze, does not get sick, is unpretentious to the soil, always a wonderful harvest! And compote is lovely.Will_brothers
To all the advantages of simple cultivation, one but fatty minus of processing - during the fermentation process, a lot of methyl alcohol is formed due to the “mucous” pulp. From this, Isabella and other Labrusca (including Lydia) are banned for use in the alcohol industry in Europe and the States.Wlad
Varieties of the Isabella group are very unpretentious and resistant to fungal diseases (mildew and oidium), as well as to phylloxera. It tolerates high humidity, but not drought tolerant. It grows freely in the Black Earth Region, Moscow Region and Siberia, a non-covering variety. In the country, Lydia and Isabella grew up in my country, made wine, and it would be possible to distill. But the households ate badly. I removed them, planted the cultural ones, now I don’t get it, they eat everything, and I’ll hide for the winter. Now scratch turnips? either it is necessary to plant even more, but there is not enough space, or return Isabella and Lydia.Zeman
I have a vine of Isabella for seven years and I’m not overjoyed. It withstands frosts up to -35ºС without shelter, does not require special care. He grew up in a jar of cuttings cut by a friend, grows according to the wall method, or, more simply put, put it on the arch. I saw the first bunch already in the fourth year of growth and now I collect up to 50 kg from the bush. Very tasty grapes, excellent home-made wine is obtained. This year I’ll try to keep several clusters of grapes until the New Year according to the method on green ridges, so far it’s standing well.Valentin Shatov
I have been making wine from Isabella for several years. Very tasty, and compote too. Elite varieties (over forty) have nowhere to plant, but the wife does not order to clean Isabella.Vladimir Kuznetsov
I have about 60 table grape varieties; Isabella is my favorite. This is a non-covering bush of grapes that grows under the foundation of a barn, what kind of grape variety would grow under such conditions and at the same time not only decorate the wall, but also give a good harvest? I make delicious and fragrant compotes from only one grape variety, of course, this variety is Isabella. For some time, she began to make marshmallows herself (raspberry, strawberry, currant, banana, apple, cherry, grape, cranberry); guess which one is the most delicious and fragrant, with an unforgettable bouquet and aftertaste? the final grape, and the variety is Isabella. For this reason, our family was left without grape compote in the winter, the whole Isabella went to the preparation of mashed potatoes for marshmallows. We don’t use Isabella fresh, her taste is very rich. In October we eat table varieties. I’m starting to shoot Isabella in late November or early December (depending on the weather).Irina Kiseleva
In the 90s of the last century in the grape books I met in the description of Isabella one feature that distinguishes the variety from all other grape varieties. Isabella grows three antennae, then an empty internode, then again three antennae and an internode, and so on. The rest of the grapes have two antennae, and then an empty internode. Therefore, it is impossible to confuse Isabella with other varieties.Vladimir 63
My natural Isabella has never matured - even in the abnormally hot 2007. We are suitable only for re-grafting. Taiga is well kept on it - excellent splicing and vines per year of vaccination under 4 m.Alexander Zelenograd
My Isabella ripened in the first ten days of September, usually this happens later, but no later than October 5th. Vines grow 8–10 m in a year. They are not at all susceptible to diseases (only spiders love clusters). Even when everything around is white with powdery mildew, it does not affect it in any way. A neighbor has a bush for about 20 years - completely braided two apple trees and two walls of the house (no pruning) - there are so many grapes that there are no apples, I think no less than 100 kg.Nikolay-Moscow
Isabella is a grape variety ideal for the novice gardener. The taste of berries, of course, is not liked by everyone, but the culture has a host of other advantages. Caring for Isabella will not take much time and effort, especially if the climate is suitable. But even in conditions that cannot be called ideal, this variety stably and abundantly bears fruit, standing out by its consistently high quality berries.
