Best grown in organically rich, slightly acidic, medium moisture, well-drained sandy loams in full sun to part shade. Sharp soil drainage is essential. Plant bulbs in early to mid fall. Planting depth depends upon bulb size. In St. Louis, each bulb should be planted 2 to 3 times the height of the bulb, with at least 3\ of soil over the top. After the flowers have bloomed in spring, the top portion of each flower stem may be removed, as practicable, to prevent seed formation, but foliage should not be cut back until it begins to yellow. Flowers usually face the sun, so bulbs should be grown with any shade areas at the rear of the planting. Bulbs can be left undisturbed for a number of years. If bloom quality and quantity decline over time, clumps may be divided by digging just after the foliage dies back."
