Culture: Prefers full sun (if adequate moisture is provided) to part sun; must get at least six hours of direct sunlight. Plants that do not bloom heavily or at all may not be getting the right amount of sunlight. Grow in a moist to wet soil; can also be submerged at the soil level in aquatic plantings and containers. Heavy feeders. If using an aquatic fertilizer, check for fertilizer rates before application. For added winter protection, mulch plants in Zones 6 to 7. Must dig rhizomes in late fall in areas with winters where temperatures are consistently below 0 degrees. Store rhizomes in sand or peat in a cool, dry location for the winter. Propagated by division. No serious pest or disease problems; borers, slugs and caterpillars may be a problem.

Special Notes:.Valued for its colorful tropical foliage and blooms, verticality in the landscape, and ability to grow on land and in water. Attracts hummingbirds.
