Yellow star-grass is a delicate native wildflower that thrives in open woods, meadows, and prairies with partial shade and average moisture. Plant it in well-drained soil and water regularly during dry spells, but avoid soggy conditions. It spreads slowly from a corm and makes a charming, low-maintenance addition to native plant or rock gardens.
