One more interesting characteristic: this is a half-parasitic plant. The roots of the cow-wheat are small and only poorly developed, but these roots are the means by which it fastens on to other, stronger plants and takes up part of its necessary nutrients. This can be from larger bushes or from trees. The host plants have a large and well developed root system and don’t mind such a "small and temporary thieving”.
