Cirsium arvense, perennial herb, flowers are collected in inflorescences baskets. After
flowering , fluff with seeds is visible
The leaves form a basal rosette , from which then a stem grows from 30 to 200 cm high; at the top of the stem branches.
The plant is usually dioecious , propagates well vegetatively. It happens that a colony ( polycormone ) is formed only from individuals of the same sex. Then the plant blooms, but does not give seeds. The flowering time in the European part of Russia is from June to October .
Field Cirsium is a hard-to-eradicate weed of cereal fields, vegetable gardens and young plantations. Sometimes an artisan due to vegetative propagation can fill the entire field, crowding out cultivated plants. It is also found in nature in meadows , in bushes , along roads in the lowlands and in the mountains.
A strong core root can penetrate 2-3 meters, sometimes 5-6 meters long roots are found. Approximately at a depth of 35 cm from the main root, tuberoid thickened roots containing a supply of nutrients extend parallel to the surface.
The plant is a good honey plant .
Previously, bundles of “fluff” and flowering plants were used as material for stuffing animals .
There is evidence of the use of plants in folk medicine .
Taxonomically complex and polymorphic; according to most modern taxonomists, it is actually a subgenus of several root-spawning dioecious species. According to a simplified understanding of the boundaries of the species, there are varieties :
- Cirsium arvense var. argenteum
- Cirsium arvense var. integrifolium = cirsium setosum
- Cirsium arvense var. mite
- Cirsium arvense var. vestitum = Cirsium incanum
Occasionally individuals with pure white inflorescences are found.
