Best grown in fertile, humusy, organically rich, medium to wet soils in part shade or filtered sun. When growing plants in garden soils, provide regular moisture, especially during dry summer periods, and do not allow soils to dry out. Plants may also be grown as pond marginals in up to 6" of standing water.
Plants produce prodigious amounts of growth and appreciate regular fertilization during the growing season. Site plants in locations protected from strong winds. Tubers may be left in the ground year-round in USDA Zones 8-10. In northern states, however, tubers should be planted in the ground in mid-spring (after April 20), dug up in fall after first frost and then overwintered in a cool dry location (set in dry peat or wood shavings) where temperatures do not dip below 45 degrees F
This species is also commercially grown as a food crop in Hawaii (poi is made from the tubers) where it is commonly called taro.
