Overview

Alternanthera ficoidea is a tender perennial typically grown as an annual, reaching 6-18 inches (15-45 cm) tall and 12-18 inches (30-45 cm) wide depending on cultivar. Habit is mounding to spreading with branching stems that root at nodes when in contact with moist soil. Leaves are the primary feature: opposite, lance-shaped to spatulate, 1-3 inches (2.5-7.5 cm) long, with cultivar colors ranging from yellow-green and chartreuse through orange, copper, red, magenta, and burgundy; many cultivars have variegated leaves with pink, cream, or yellow patches. Flowers are inconspicuous — small whitish clusters in leaf axils — and form sparingly in temperate climate annual culture. Stems are slender and slightly hairy. Growth is moderate to fast at 6-10 inches (15-25 cm) of new growth per month during warm weather. Frost-tender: foliage damages below 40°F (4°C) and the plant dies to the roots at 32°F (0°C). In zones 10-11 the plant overwinters as a low evergreen groundcover. Cultivars vary in habit from compact mounding forms 6 inches (15 cm) tall used for bedding and edging to trailing forms 12-18 inches (30-45 cm) used for hanging baskets and container spillers. Color intensity is highest in full sun; partial shade reduces red and orange pigmentation. Foliage of A. ficoidea is sometimes confused with A. brasiliana, which has larger leaves to 4 inches (10 cm) and a more upright habit.

Native Range

Native to Brazil and other parts of tropical South America, where it grows in moist disturbed soils, riverbanks, and forest edges at low to moderate elevations.

Suggested Uses

Used as a bedding annual in massed plantings, edging, and parterre designs at 8-12 inch (20-30 cm) spacing. Container culture in 1+ gallon (4+ liter) pots as a foliage filler or trailing spiller in mixed plantings; combines with petunias, calibrachoa, and ornamental grasses. In zones 10-11 used as a low evergreen groundcover at 12-15 inch (30-38 cm) spacing.

How to Identify

Identified by opposite lance-shaped to spatulate leaves 1-3 inches (2.5-7.5 cm) long in cultivar-dependent colors of chartreuse, orange, red, copper, or magenta — often with variegated patches of pink, cream, or yellow. Stems slender, slightly hairy, with leaves arranged in pairs at each node. Flower clusters small, whitish, inconspicuous, forming in leaf axils. Distinguished from A. brasiliana by smaller leaves (1-3 inches versus 2-4 inches) and from A. dentata by lance-shaped (rather than ovate) leaves.

Bloom Information

Flowers are inconspicuous and the species is grown for foliage color rather than bloom. In zones 10-11 small whitish flower clusters may appear in leaf axils from late summer through fall. In annual culture (zones 3-9) the plant is typically pinched and sheared frequently for foliage display, which suppresses flowering.

Care & Maintenance

Care Guide

Water 1-2 times per week during the growing season; the plant tolerates short periods of drought once established but foliage color dulls and lower leaves drop in prolonged dry periods. A balanced 10-10-10 fertilizer applied at half strength every 4-6 weeks maintains foliage color; high nitrogen fertilizers promote green growth at the expense of red and orange pigmentation. Spider mites occur in hot dry conditions, particularly on container plants brought indoors. Aphids cluster on new growth tips in spring. Plants are killed by the first hard frost and are typically replaced annually in zones 3-9. In zones 10-11 the plant persists as a low evergreen groundcover but may be cut back hard in late winter to refresh foliage.

Pruning

Pinching shoot tips every 2-3 weeks during the growing season maintains compact habit and intensifies branching. Shearing back by one-third in midsummer when growth thins refreshes the foliage display. Trailing cultivars in containers benefit from light tip-pinching to maintain shape; aggressive shearing reduces the cascading length.
