Soil Description: Well-drained limestone soils preferred, but also does well in sands, loams, clays, caliches, granitic, and rocky soils. Minimal organic content the norm. (Source: wildflower.org)
Conditions Comments: Allow to dry out between waterings, as this will encourage more extensive waves of blooms. Avoid excessive water and fertilizer, as that can lead to overly rapid growth, fewer blooms, and a weaker plant. Prolonged saturation can result in rot. Won’t grow as fast or get as large in clay soil but won’t suffer there either. Can be drought-deciduous in some regions. Can survive temperatures as low as 10 degrees F. (Source: wildflower.org)
