Common Goldstar is a low, tufted, grass-like plant that grows from a hard corm. The corm is hard and hairy. It is found growing in open woodlands, abandoned fields, lawns, prairies, and other open areas. Although not an aggressive plant, it can spread to form colonies.

Its close resemblance to grass is only distinguishable when the plant is in bloom. Flowers appear on stems that are shorter than the leaves.

Carpenter bees, Mason bees, and Halictid bees are attracted to the blooms. Some flies and beetles feed on the pollen. Small rodents may eat the corms.

Yellow Star Grass is a significant nectar and pollen source for native bees, flies, and beetles.
