Arctic chrysanthemum (lat. Chrysanthemum arcticum) - a representative of the genus Chrysanthemum of the Asteraceae family, or Astrovye. In nature, the species grows mainly in European countries, as well as in the United States, and is often found in Asia. Refers to undersized species. It is still actively used in ornamental gardening. Outwardly, it resembles a garden chamomile.
Characteristics of culture
Arctic chrysanthemum is represented by perennial herbaceous plants, not exceeding 30 cm in height. In the process of growth, the plants form loose, but very attractive carpets, completely covered with baskets.
The stems of the species under consideration are of the creeping type, they, in turn, are crowned with deeply dissected green foliage. The foliage located at the bottom of the shoots is petiolate. Inflorescences - baskets, tubular flowers - yellow, ligulate (marginal) - white.
The flowering of the culture is observed in late summer - mid-autumn, which depends on climatic conditions and care. Today it is used to decorate rocky gardens, rustic gardens and alpine slides.
Participation in selection
Arctic chrysanthemum is rarely involved in breeding, however, thanks to its crossing with Weirich's chrysanthemum (Latin Chrysanthemum weyrichii), a rather interesting and highly decorative group of chrysanthemums - Siberian chrysanthemum - was obtained.
Nowadays, this group is very popular among gardeners living in regions with a cold climate, because it easily winters even in Siberia. Moreover, flowering forms tolerate frosts down to -8C without any problems.
It should be noted the arctic chrysanthemum variety, referred to as Roseum. It is characterized by inflorescences, the ligulate flowers of which are pink in color. Like the main species, the variety in question is unpretentious and frost-resistant.
It is also resistant to pests and diseases, although in unfavorable years it is attacked by a field bug, brown chrysanthemum aphid, a slobbering captive and a spider mite. Among the diseases are possible: gray rot, powdery mildew, leaf septoria, rust, verticillosis, etc.
Growing features
As already mentioned, arctic chrysanthemum is not a whimsical plant. It accepts clay soils and rocky areas, however, provided there is good drainage and good permeability. The species in question will not tolerate community with waterlogged, saline and heavy soil, in such areas it feels defective, which, as a rule, leads to death.
The location is preferably sunny with diffused light; in highly shaded areas, plants are stunted and bloom poorly, and sometimes do not bloom at all. Strong winds will not interfere with the crop, because it cannot boast of tall stems, however, the impact of cold winds will negatively affect plant health.
The arctic chrysanthemum can be propagated both by seed and vegetative methods. The second involves grafting and dividing rhizomes. The listed procedures are carried out in early spring. When grafting, cuttings cut from the apical shoots are planted in a mixture of sand and peat, where they root rather quickly, after which they are transplanted to a permanent place.
When planting seedlings, and rooted cuttings, a distance of 25 cm is observed between the plants. It is not recommended to plant plants too close to each other, there is a high probability of disease and slow development. There are no other requirements, except perhaps timely watering, weeding at the initial stage of growth and feeding twice a season (before and during flowering).
