P. Unusual but very attractive plants with blooms shaped like cannas, for cool, shady positions. Plant in a leafy compost and water as necessary in summer. Height about 10 in. Increase by division in spring. Roscoea cautleoides has large, yellow flowers in late summer, about 6 to a spike. R. humeana is purple and R. purpurea procera white with mauve markings.
