Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained loams in full sun. Plants form dense, slowly-spreading clumps over time. They perform best in dry, sunny areas of the garden. Established plantings have good drought tolerance. Plant new bulbs 2-4" deep in fall. Established plants may be divided in fall. Bulbils that may form in the umbel may also be planted in fall. Plants may self-seed in the garden. Deadhead flowers before seed sets to help control any unwanted spread.
