Flower colors include yellow, pink, cream, white, lavender, peach, apricot, and salmon. The mottled foliage is also attractive. After the foliage has darkened in fall, dig and store the rhizomes in dry sand or vermiculite in a cool, frost-free area. They are particularly effective in containers as patio plantings. Plant corms 2 inches deep in full sun to part shade and a moist, well-drained soil.
Flower colors are predominately lilac-blue to white.
Container plantings make it easy to bring the plants indoors for the winter. Given plenty of sun indoors, they will continue to bloom throughout the winter. Some varieties are giants reaching up to 6 feet tall. Use these garden giants as temporary screens or hedges. Dwarf forms reaching only 2-3 feet tall are also available.
