Plant in deep, well-drained soil enriched with plenty of well-rotted manure or compost in full sun. In warmest areas, shade the plants from intense summer sun. Thrives in areas with long, cold winters and mild summers. Space 24-36" apart. Plant the fleshy roots so that the eyes are no more than 1-2" deep. Support plants and their heavy blooms with hoop-type stake. You may notice ants on the flower buds; it is a symbiotic relationship and does not hurt the plant. Water deeply in periods of drought. Grows 36-48" tall. Blooms May. Hardy in zones 3-9.
