A low, tufted, grass-like perennial, eastern yellow star-grass grows 3-8 in. tall from a hard, hairy corm. The hairy, grass-like leaves originate from the base of the plant. Slender, thread-like flowering stems may be erect or reclining. They carry 3/4 in., star-shaped, yellow flowers below the top of the leaves.
This small plant can easily be confused with a grass unless its distinctive flower is seen.
