Best grown in rich, organic, well-drained soils in dappled sun or bright shade. Avoid full sun or full shade. Best in cool summers. Dislikes high heat and humidity. Can be tricky plants to grow well. Keep soils consistently moist through regular watering, but avoid over watering. Protect from strong winds, but provide good air circulation. Regular fertilization during the growing period produces most profuse bloom. Start plants indoors in late winter about 2 1/2 - 3 months before time to set out. Set outside only after all threat of frost is over.
Plant tubers shallowly with concave side up. 3-4 tubers per hanging basket or space 12-18" apart in borders. Taper off watering in fall when leaves begin to turn yellow. Before first fall frost, store containers in frost free location or dig up tubers and store. If tubers are to be dug up, lift, shake off soil, dry and then cover with a dry medium such as perlite, vermiculite or peat.
Store until time to replant in late winter in preparation for the next growing season. Container plants may be brought indoors in fall and grown as winter houseplants.
