Many, having first seen this vegetable, wonder: what is cauliflower or broccoli? In fact, this is a Romanesco, or Roman cabbage, whose inflorescences are not just edible, but very tasty and healthy.
What is romanesco
Romanesco cabbage is a member of the Cruciferous family, the most famous representatives of which are different cabbage varieties. Yes, and Romanesco is also a type of garden cabbage. By its appearance, it resembles a color one, but its pale green flowers form intricate pyramids, arranged in a spiral, which gives the vegetable a special beauty. The “construction” of the Roman cabbage consists of smaller elements imitating the shape of a large inflorescence, and those in turn are formed from an even larger number of smaller copies. And all of them with mathematical precision are arranged in smooth spirals. Captures, right?
Compared to cauliflower, romanesco is more tender and has a sweetish aftertaste. Compared to broccoli, its stems are shorter and softer, so it quickly prepares and is suitable for use in raw form. And the most delicious inflorescences are small, about 10 cm wide.
This bright green vegetable looks rather strange, but very beautiful. It is enough to see a romanesco once and not to confuse it with other vegetables. Outwardly, it is so bizarre that some people sometimes joke that aliens sowed this cabbage on Earth, and others consider it to be an ornamental plant.
Today it is considered that romanesco is a mixture of cauliflower and broccoli. Although some researchers refute this theory, since, according to their calculations, the Roman existed long before the cauliflower. It is said that the Etruscans, who lived in the first millennium BC, began to grow it first. They brought this culture to Tuscany, from where Roman cabbage spread to other regions. According to another version, this culture was first identified in Italy in the XVI century. But despite such a long history, the vegetable entered the world market only in the 90s of the twentieth century. This explains why Roman cabbage is not yet so popular and less studied than its "sisters."
Benefits for man
The aroma resembles a cauliflower, but with a slight nutty "flavor". Scientists and nutritionists consider romanesco one of the most easily digestible vegetables. But in addition to the amazing appearance, this vegetable can boast no less amazing chemical composition. And although scientists continue to explore the characteristics of this culture, but even on the basis of what we have already learned about it, we can say that it is one of the most useful vegetables on the planet.
Romanesco is a low calorie diet product that is rich in vitamins and minerals, making it ideal for a vegetarian diet.
As part of the vegetable scientists found vitamins B, A, K, C, folic acid, fiber (although slightly less than broccoli), iron, manganese, carotene, zinc, omega-3 fatty acids and useful amino acids. And, importantly, it is easily portable food for people with sensitive stomachs.
Similarly, other cruciferous romanesco is famous for its many health benefits. Having studied the properties of this "cosmic" cabbage, scientists have concluded that it has amazing properties. In the body, it works like:
- antiviral agent
- antibacterial drug
- antimicrobial agent
In addition, the vegetable protects the eyes, strengthens the immune system, improves the functioning of the heart, vessels, organs of the respiratory system, has benefits for the health of bones and muscles, cleanses the blood and protects the central nervous system (brain, spinal cord, nerve endings). Romanesco helps fight viral infections, is useful for treating flu and colds, improves lung health, activates brain function and has a beneficial effect on muscle tissue.
What does science say
In the cabbage Romanesco scientists have found a flavonoid compound, known as kaempferol. It is believed to be able to destroy cancer cells and prevent the formation of new ones. Among other properties of kaempferol is called anti-inflammatory, antimicrobial, antioxidant, cardio and neuroprotective effects.
This flavonoid is able to prevent diabetes, osteoporosis, allergies, has analgesic properties and regulates hormones.
There are cabbage and such chemical compounds as sulforaphane and isothiocyanates, which increase the ability of the liver to remove carcinogenic toxins, thereby preventing malignant cell degeneration. The anti-cancer efficacy of these substances has been laboratory proven in cells of the bladder, breast, colon, prostate and ovaries.
The high content of carotenoids improves the appearance and tone of the skin. Rich reserves of iron, folic acid and vitamin C (100 grams of vegetable have the daily norm of ascorbine) make Roman cabbage an excellent choice for those struggling with anemia and infertility. And people suffering from a lack of taste or a "metallic" taste in the mouth, argue that romanesco helps to eliminate these symptoms. Researchers say that all this is due to zinc.
It also helps regulate blood sugar levels, control inflammation, improve bone density. Fiber, which is part of the vegetable, improves digestion, while providing a feeling of "fullness", which is useful for maintaining a healthy body weight. A low calorie content makes the product an ideal ingredient for a weight loss diet. Since Roman cabbage is a cruciferous family, it contains glucosinolates, sulfur and nitrogen-containing compounds, which naturally clean the kidneys.

To improve the taste of the dish is seasoned with sauces of various types.
Recipes with romanesco cabbage:
- Salad. Cabbage is boiled in a cabbage, not disassembling into inflorescences. It should be lowered into salted boiling water for 10-15 minutes, as soon as the pulp has become soft, it is necessary to remove it so that the romance will not have time to fall apart. Turkey fillets, about 300-350 g, cut into cubes and stew with vegetables: onions, bell peppers and carrots. All vegetables should be finely chopped - seeds are removed from the bell pepper. Meat should be brought to full readiness. Until fully cooked and boiled green beans. The ingredients are mixed - the vegetables are not removed. If you used a lot of oil during frying, it is better to leave the frying in a colander for a while - the oil will drain. Salad dosalivayut, pepper to taste, add chopped garlic.
Cabbage in cheese sauce. While the romanesco is boiled in boiling water (no need to disassemble the inflorescences), you can deal with vegetables. Carrots - 1 large or 2 medium - cut into cubes, onions - 1 onion - chop finely. To the cut add 100 g of frozen green peas and fry all together in a deep frying pan in vegetable oil. Vegetables need to be mixed periodically. Romanesco disassembled into inflorescences. The sauce is prepared separately: hard cheese, 100 g, rubbed on a fine grater, poured into 20% cream - just over half a glass, put on a slow fire. As soon as the cheese is melted, the sauce is poured into the pan, salted, bring the contents to a boil and turn off. You can add fried flour to the sauce - this will make it thicker. Before serving, the dish has to be cut - the cheese binds all the ingredients.

Interesting facts about romanesco cabbage
Disputes about the origin of the cabbage romanesco still going on. Not all biologists agree that the seeds of plants in the culture layer, the formation time of which is estimated by 1 century BC, is from Roman cabbage. It is believed that it spread at the end of the twentieth century only because breeders fought long over its creation, combining broccoli and colored varieties. It is such disputes that make Romanesco treat with caution - buyers fear that when creating a variety, the achievements of genetic engineering were used.
If you grow romanesco yourself, you can be sure of its absolute naturalness. On the one hand, this is not difficult to do: in order to get a decent harvest, it is enough to carry out the same measures as when sowing cauliflower: feeding, processing, regular watering, etc. But it is necessary to take into account that the culture is more capricious and dies with the slightest thermal fluctuations.
The study of cabbage romanesco, because of its original appearance, was studied not so much by biologists as by mathematics. Its form completely repeats the Fibonacci spiral. All radii of the vegetable arcs fully comply with the calculated sequence. Each of the inflorescences is composed in a similar way - that is, its shape completely coincides with the shape of the plant itself. Maybe it was Fibonacci, the famous mathematician of Medieval Europe, the generic name of Leonardo of Pisan, after seeing this vegetable in the garden, calculated the sequence of numbers for his pyramid?
For people trying to control their own weight, and for vegans, this vegetable is the perfect ingredient on the menu.

Description of the variety and characteristics
Romanesco is an amazing variety that delights with its decorative effect. The fruit is a complex of inflorescences that resemble pyramid corals with many round protrusions. They are securely covered with dense blue-green large leaves. The variety has received two more "popular" names: "Romanesque broccoli" and "coral cabbage".
Romanesco is a type of cauliflower, so the farming of these vegetables is largely the same.
Homeland varieties consider Italy. It is here that genetics have worked on the breeding of this hybrid. Subject to the rules of cultivation, receive specimens, reaching a height of 100 cm.
Romanesco tastes closest to broccoli, but has its own characteristic nut-creamy flavor. Vegetable suitable for frying, roasting, blanching. In the preparation of cabbage of this variety there is one feature: it cannot be subjected to heat treatment for a long time, since it is possible that not only taste but also nutritional properties may be lost.
Choosing a landing site
Romanesco cabbage, the cultivation of which will not be difficult, prefers neutral, not acidic soil. An important criterion for choosing a landing site is what kind of culture was here last season. Best predecessors:
You should not plant romanesco on those beds that were occupied by radish, other varieties of cabbage, radishes, onions last year. It is recommended to prepare the ground before planting the Romanesco.
- To introduce ash or dolomite flour at the rate of 200-300 g / m 2.
- Dig the soil with manure or compost at the rate of 2 buckets per 1 m 2.
The optimal soil for planting cabbage of this variety is black soil or loam. A vegetable bed can be prepared in the fall, reducing the acidity if necessary by adding ash and fertilizer, digging shovels on a bayonet.
Growing romanesco seedlings is no different from the technology of growing cauliflower. Sowing seeds produce in such a way as to plant seedlings in open ground in 45-50 days. For the southern and northern regions, these are different landing times. When growing romanesco in the middle zone, seeds are sown in mid-April.
Planting material is pre-soaked for several hours in warm water. Then planted in separate containers. Most often use small plastic cups. The optimum temperature for seed sodding is + 18-20 ° C. After seedlings appear, it is necessary to reduce the temperature during the day to + 12-15 ° C. At night - up to + 6-8 ° С. In this way, seedlings are hardened, which is especially important for growing romanesco in regions with a climate that is quite harsh for heat-loving crops.
It is not recommended to keep the seedlings in well-lit places. This is fraught with stretching the stems and the slow formation of leaves.
Planting in open ground
Seeds planted in mid-April by the end of May will become strong, stocky plants. At this time their transplanted into the open ground.
The procedure consists of several stages.
- In the prepared garden make holes at a distance of 40-50 cm from each other.
- Carefully remove the plant from the cup along with the earthy clod.
- Immerse it in the hole so that the base of the stem is at ground level.
- Fill the hole with earth and slightly condense it.
- Water the plants.
Calendula and marigolds can be planted along the bed perimeter. They are able to deter pests.
For romanesco recommended moderate watering. It is important to prevent drying and waterlogging of the soil. With a lack of water, the inflorescences may not start. Watering the cabbage should be under the root, avoiding the ingress of fluid on the outlet and the cabbages.
You must regularly inspect the plants for pests. To combat them, tobacco dust or sifted wood ash is sprayed over cabbage every 10-14 days.
Also compulsory care is the timely removal of weeds. Periodically spiked to the roots of the soil and humus. If the summer is too hot, to prevent burns and drying of the ovaries, the leaves above the head lift and tie.
In order to control weeds and retain moisture, several times a season, the ground in the garden is covered with a thick layer of dry grass.
During the vegetative season, romanesco cabbage is fed three times.
- 7-8 days after planting seedlings. Pour over a solution of mullein or poultry manure prepared from 10 liters of water and 0.5 kg of organic matter. In the resulting solution is recommended to make 20 g of complex mineral fertilizers.
- After 14-15 days after the first feeding. For this purpose, prepare a solution of 10 liters of water and 2 tbsp of superphosphate, add 2 g of boric acid and potassium chloride.
- Carried out during the beginning of the formation of cabbage heads. The solution is prepared from the following ingredients: 0.5 kg of mullein or bird droppings, 2 tablespoons of superphosphate and ammonium nitrate, 1 tablespoon of potassium chloride, 10 liters of water.
Completed feedings are enough for the normal development of the plant and the formation of the fetus.
This disease is otherwise called “wet bacterial rot.” Get rid of it is quite difficult. It is important to perform a number of measures that reduce the risk of plant damage by this disease:
- Disinfect the seeds before planting seedlings, keeping them for 2-3 hours in a weak solution of potassium permanganate.
- Disinfect seeding containers.
The first sign of the disease - the appearance of watery spots on the sheets and flowers. The affected areas quickly increase in size and begin to rot. Methods of struggle:
- with a sharp knife cut out the spots,
- if it is not possible to remove all the affected areas, the plant is removed from the bed and burned.
This disease can occur at the stage of growing seedlings. The first sign of trouble is the darkening of the base of the stem. Вскоре эта область приобретает бурый оттенок, становится водянистой и загнивает. Заболевание вызывается грибками р.Olpidium, р.Pythium и Rhizoctonia solani. Чем старше растение, тем оно устойчивее к «черной ножке».
Основная мера профилактики заключается в правильном поливе, не допускающем заболачивания грунта. Важна и дезинфекция. При необходимости, почву пропаривают. В особо сложных случаях рекомендована полная замена грунта. Measures to combat the disease are in the treatment of land and plants with sulfuric preparations.
The first signs of this disease are so invisible that you can skip them. The mosaic begins to declare itself by the appearance of yellowish, randomly arranged veins on the leaves of cabbage. This is a viral infection, the fight against which is quite complicated. It consists in the treatment of plants Bordeaux liquid.
Of the pests most often appear aphid, cabbage fly, cabbage, cruciferous flea, slugs. Get rid of them through the use of insecticides. Among them are the means of complex action and specialized to combat a particular type of pest.
Removed romanesco in mid-autumn. By this time elastic dense heads of cabbage ripen, which are cut with a knife at the base of the plant.
It is important not to overdo the cabbage on the bed, as it can lose some of its useful properties.
Fruits differ in a low keeping rate. Within 10-14 days they can be stored in the refrigerator. If you freeze the cabbages, they can be stored for much longer without losing their nutritional value.
With all the recommendations for growing Romanesco cabbage, a high yield of this valuable vegetable is guaranteed. It will delight with its external beauty and high taste.
