What is a decorative bow allium, photo and description
Allium belongs to bulbous perennial plants. Unfortunately, this representative of the flora is not widespread enough and is not very popular with domestic florists. And very much in vain. Today, botanists have more than seven hundred onions, differing in size, time and duration of flowering, the palette of flower colors and its shape.
The duration of flowering is long, about three weeks, but the inflorescences themselves, if not removed at the end of flowering, also look quite picturesque.
Allium flowers decorate the garden, but they are also suitable for cutting, they can be used in summer bouquets or used as dried flowers.
The plant is attractive and because it does not require a lot of space for growth, it is an excellent honey plant.
From the name itself, it is easy to guess that it is a close relative of the rather common, familiar to us, onions and garlic.
The native land of the plant is Central Asia; it gained popularity in Europe only from the beginning of the nineteenth century.
Botanists from the Imperial Botanical Garden of St. Petersburg contributed to the spread of decorative bulbous crops, who, in fact, collected a collection of the most beautiful representatives of the species and started breeding new varieties.
With the exception of Schubert and Christoph varieties, alliums are resistant to low temperatures, are not particularly demanding on soils, and withstand drought well.
For planting bulbs, you should choose well-lit areas, the plant will feel much more comfortable, and therefore the appearance will be more decorative.
It is not necessary to dig up the bulbs annually; they can grow in the same area for several years.
If desired, allium can even be grown in a regular flower pot.
To begin with, it is not so easy to buy ornamental allium onion bulbs, not every garden center will offer you at least a couple of varieties of this plant.
There is a much wider choice in online stores, so in order to save time and money, it is easier to immediately look for sites offering seeds for planting.
It is advisable to plant onions in the fall. As a last resort, resort to spring planting. Autumn planting is carried out in September or early October, when the air and soil temperatures drop.
The depth of the wells for should be about twice the height of the bulbs. The prepared wells are slightly moistened.
On one square. meter, you can plant up to 50 bulbs of large plants or up to hundreds of small ones.
After planting the bulbs, the site is covered with a thick layer of mulch (peat or humus), watered abundantly. The formation and growth of roots continues until the soil temperature drops below +3 C.
Top dressing and watering
Fertilize the soil when digging, before planting the bulbs. Fertilizers can be used both mineral and compost. The next plant feeding is carried out by loosening the soil in spring. When choosing a fertilizer, one must remember that the plant is very sensitive to a lack of potassium.
You can also feed the plants during the budding period.
At the very beginning of autumn, the last top dressing of the season is made: wood ash is added.
Alliums do not need abundant watering, they should be moderate and be done only if the soil is very dry.

Decorative allium onion: is it necessary to dig it out after the end of flowering
Since the plant is an ephemeroid, an annual digging procedure is not necessary. You can plan a transplant in 5-7 years. Onions overwinter in open ground, without shelter.
But you should take into account the weather conditions in a particular area: too rainy and cool autumn can cause the development of putrefactive processes in the bulbs. In such cases, it will be rational to dig up the bulbs, dry them and plant them in the ground.
It is recommended to extract the bulbs from the soil after the leaves have completely wilted. If the second half of summer is dry and warm, then it is better not to touch the bulbs.
Almost all varieties begin to bloom in May, more precisely, in the second half of the month. The inflorescences themselves look quite attractive, they can have different sizes and colors. The diameter of the inflorescence of the largest of the decorative bows reaches 20 cm in diameter.
The flowering time for each variety is different, from a couple of weeks to two months. When choosing planting material, it should be borne in mind that the flowering of some varieties, for example, Allium pulchellum, begins in August.
Possible reasons for the lack of flowering
Complaints about the lack of onion flowering can be heard very rarely, even novice gardeners can grow a beautifully flowering plant.
However, the cases are different, for example, flowering may be absent:
- with an incorrect landing;
- for the reason that it is too young;
- when landing in a wetland;
- with strong freezing in winter.
It will also not be possible to get abundant flowering with excessive watering.
The use of allium in landscape design
Different varieties of onions are used to create green compositions that adorn city streets, parks, and private plots. This plant fits perfectly into the pictures of rockeries and alpine hills, stone gardens, it can be planted as border plantings, in group flower arrangements.
When choosing varieties, the flowering period of plants is taken into account:
- early flowering;
- average flowering period;
- late flowering.
It is also important to know the height of the plants:
- tall, peduncle length from 80 cm;
- medium-sized, peduncle from 40 to 80 cm;
- undersized - up to 40 cm.
When planning the planting of ornamental onions, it should be borne in mind that the first, basal leaves of plants quickly turn yellow, naturally, the attractiveness of the plant decreases. To preserve the decorativeness of the flower bed, other low-growing plants should be placed in such a way that they cover the leg of the allium.
As for the location of the plants themselves, the dwarf varieties of allium look more impressive in a group planting, tall ones can be planted both in groups and one at a time.
Geranium, ornamental poppy, hostu, herbaceous peony, irises, cuff can be planted as companion plants next to onions.

Is it possible to eat decorative allium bow
Even by the name of the plant, it can be assumed that it is more decorative. Leaves and bulbs are distinguished by a rather pronounced aroma and original taste. Besides. all parts of the plant have healing properties.
Onion leaves can be added in small quantities to spring salads, but the period of edibility of the leaves is limited, it ends with the beginning of the formation of the peduncle. Leaves from a flowering plant are not recommended for food.
Bulbs are used for baking and pickling, but they should not be consumed in large quantities, one must take into account the rather high risk of developing an allergic reaction.
The beneficial properties of allium are due to the high content of vitamin C, vitamins E and D. Traditional medicine offers the use of the product as a means for the prevention of oncological diseases, fortifying and increasing immunity.

- heals gastrointestinal diseases;
- helps to defeat colds;
- onion juice accelerates hair growth.

There are two ways to increase the number of plants: by sowing seeds or vegetatively.
Seeds can be sown in spring or autumn, picking is done directly in the beds, it is recommended to choose areas well-lit by the sun.
Some types of onions, such as giant and stemmed onions, sprout only when sowing in winter.
The flowering of varieties such as anzura and wild garlic will begin only at 4-7 years of plant life, by this age the bulbs will gain weight, which is necessary for the reproductive process.
The vegetative method involves planting babies that form on the mother's bulb.
For the reproduction of rhizome species, the division of the bushes is used.
Diseases and the fight against them
Diseases and pests rarely have a negative impact on the condition of bulbous plantations. The pungent smell scares away harmful insects and rodents. Of the diseases, the most dangerous is rot, from which the underground part of the plant can suffer with excessive soil moisture.
Failure to follow care recommendations, in particular, excessive soil moisture, can lead to damage by downy mildew or various types of rot. An onion fly or root mite can also harm the plant.
Preventive measures include:
- warming the bulbs before planting for 10 hours at a temperature within +40 C;
- treatment of affected plants with 2% chlorophos solution;
- peat mulching;
- pollination of the plant with wood ash or tobacco dust.
