Culture

Winter hardy to USDA Zones 10-11 where they are easily grown in moist, organically rich, fertile, well-drained soils in full sun to part shade. Prefers some afternoon shade in hot summer climates. In St. Louis, grow in containers which may be sunk to the rim in garden areas or placed on patios or decks throughout the growing season. Plants are quite sensitive to frost, however, and containers must be brought indoors to a cool bright room for overwintering as houseplants before first fall frost. If plants are too large for the house, they may be cut back in fall to 6-8”, forced into dormancy and stored in a cool dark corner of a basement or frost-free garage until spring. Plants of this genus are often grown as annuals, however the best flowering usually occurs on mature plants that are overwintered indoors each year. Plants of this species are often hard to find in commerce, and consideration should be given to taking cuttings from favorite plants in late summer or to potting up plants grown as annuals for overwintering.
