Sow outdoors in well drained, warm soil after all danger of frost. In mild climates, plants may be started in late summer for fall blooms or start indoors four to six weeks before last frost but note that delicate roots do not transplant well. Plant in full sun, or part shade in hot areas. Water consistently and do not fertilize.
Nick the seed coat and soak in warm water 24 hours before planting to encourage germination.
