Alternanthera dentata

Tropical perennial that is winter hardy to USDA Zone 10 and is grown exclusively for its colorful foliage. Best grown in organically rich, consistently moist, well-drained soils in full sun to part shade. Best foliage colors are developed in full sun. Soils must not be allowed to dry out. In the St. Louis area, it is typically grown outdoors as an annual, but may also be grown indoors as a houseplant as long as it is sited in a bright, sunny location and soils are kept moist. Plants may be grown from seed by starting them indoors in late winter and transplanting them outdoors after last frost date. Quality of leaf color may vary considerably and only the best seedlings should be selected for inclusion in the planting. Pinching stems or shearing will keep plants compact and bushy. For those who do not wish to plant seed, some of the more popular varieties are available from nurseries in cell packs or flats. Smaller plants may be potted up and brought inside in winter. In the alternative, tip cuttings may be taken in late summer for overwintering indoors.
