Planting and care
The preference is light shade to full sun, wet to moist conditions, and soil with abundant organic matter. Shallow rocky or gravelly soil is tolerated if it retains moisture during dry spells. Loosen the soil to a depth of 12 to 15 inches. The deep planting encourages the developing stem to send out roots to help stabilize the plant and perhaps eliminate the need for staking. Also, deep planting keeps plant bulbs cool when temperatures soar.
