Ecology.

It grows along rivers, in fields, in meadows, and in sandy and saline soils up to the middle mountain zone in the rigorous continental climate with severe winters.

Utilization and economic value.

This is a forage crop that deserves to be cultivated as a very frost-resistant, winter-hardy, nutritive plant. It can be used for pasture and hay, especially in areas with severe winters. Large flowers of the species are very attractive to honey bees; it is a good meliferous plant. It improves soil fertility.
