Flowers reach 5 inches high and the narrow, bladelike leaves 12 inches high. Space bulbs 3 inches apart in large masses for the best ornamental display. Mark their position on a garden plan or with golf tees, so you don't disturb them when they are dormant.
Corms divide easily after foliage has died back.
You can find white-flowered forms. Provide well-drained soil to avoid rot. They're tiny, so you'll need a lot of flowers to get a small harvest. Use them in rice and noodle dishes.
