Kentrantus is grown in open areas, rock gardens, mixborders, they are decorated with borders, paths. This plant prefers well-lit places and perfectly tolerates direct sunlight. Does not like drafts, dampness and cold.

Kentrantus: growing and care
The soil for kentrantus should be air and water permeable, moderately dry, and calcareous and fertile in composition. The plant can do without additional fertilization, but if the soil is not suitable for it, then fertilization can be applied 2 times a month (during the period of active growth, nitrogen-containing fertilizers are applied, then nitrogen-free). Kentrantus does not like an excess of moisture, therefore, it is watered only when the weather is very dry.
To achieve repeated flowering of centranthus, after the first flowering, you need to cut off its inflorescences to the top leaf. After a while, the plant will bloom again. And in the fall, you will need to completely cut off all the stems.
The preparation of this flower for winter depends on the climate - in warm regions, you can only cover the bush with a layer of peat, humus or just leaves. And if the winter can be harsh or snowless frosts are expected, then you need to build a good shelter: cover the cut bush with leaves, rags and cover with a film (the film must be fixed) or build a frame structure that will protect not only from the cold, but also from moisture.
For the construction of the shelter, you can also use a non-woven material - agrofibre, which is widely used by flower growers.
After 3 years, the kentrantus bush loses its decorative effect, so it needs to be updated (plant a new bush or grow from seeds). This flower is resistant to diseases and various pests, but spots may appear on the leaves in wet weather. If this happens, then the affected leaves need to be cut off, and thick bushes should be thinned out.
Growing from seeds
Kentrantus is propagated in two ways: by dividing the bush and sowing seeds. The division is carried out in early spring (before increased growth) or in the fall (after it will bloom).
Seeds can be sown both in the greenhouse and in the open ground. In the open ground, seeds are sown in the fall to the place where the centranthus should grow in the future. Before the onset of winter, crops should be covered with leaves, peat or other mulch. Another option is to sow seeds in open ground in April or May, but then there is a high probability that the plants will develop and bloom poorly.
Spring sowing is best done in homemade or special greenhouses. The best time for this is the end of February or the beginning of March. It is not difficult to make a greenhouse on your own - you just need to cover a bowl with sown seeds with foil or glass and put it on the windowsill.
Further, caring for the seedlings of kentranthus is as follows: every day we open the film or glass for airing for 5-7 minutes. After the emergence of seedlings, we gradually increase the airing time, and after 2-3 weeks we remove the glass (film) altogether. When the seedlings grow up and it becomes cramped for them, you need to make a pick - plant them at a greater distance or in separate pots. In June, it will be possible to plant Kentranthus seedlings in a permanent place.
It often happens that the kentrantus bush gives a lot of self-seeding (the seeds from the plant fall into the ground, and then germinate on their own). In this case, in the spring, you just need to transplant the mature seedlings to a permanent place at a distance of 40-50 cm from each other.
Kentransus belongs to the Valerianov family, therefore it is often called valerian. But unlike medicinal valerian, this plant does not have any beneficial properties. In floriculture, the following types of centranthus are cultivated:
- Kentrantus red (ruber)
- Kentransus narrow-leaved (angustifolius)
- Kentrantus valerian (calcitrapa)
- Kentransus longiflorus (longiflorus)
The most common species is red kentransus (often called ruber). It grows up to 1 m in height and up to 60 cm in width. Its flowers are small and collected in large domed inflorescences. In addition to the pure appearance, 3 more varieties of red kentransus are known:
- Coccineus - The flowers are bright pink, which is why it is often called crimson ringing.
- Albus, Albiflorus - white flowers.
- Rosenrot - purple-pink flowers.
In floriculture, in the second place for cultivation is the narrow-leaved kentransus - also a perennial up to 1 meter high. It is often combined with ketranthus red into one species. Kentranthus valerian is an annual plant, the height of which is only 10-30 cm. This type of kentransus blooms in April-June with pink flowers, which are collected in inflorescences.
Kentransus longiflorum is a perennial plant, the height of which is up to 1 meter. All its leaves are covered with a gray bloom. Flowering occurs in May-July, and the flowers are purple-red and collected in thyroid inflorescences.
As you can see, ketrantus is not difficult to care for and is perfect for growing in a sunny and dry place. The most popular in floriculture is red kentransus, which can be grown from seeds or propagated by dividing the bush without any problems.
