Joseph's Coat

Joseph's coat refers to several Alternanthera species grown for their brilliantly colored leaves rather than their tiny inconspicuous flowers. The name evokes the biblical many-colored coat, fitting for its patchwork foliage.

It forms low, dense mounds or spreading mats and responds well to trimming, which has made it a classic plant for formal carpet bedding and knot gardens.

Native to tropical regions of the Americas, it is grown as a warm-season annual, a houseplant, or a tender perennial, prized for season-long color from foliage alone.

(Note: the name 'Joseph's coat' is also applied to Amaranthus tricolor; here it refers to the popular foliage Alternanthera.)

• Habit: Low, mounding to spreading, typically 6-12 in tall; some forms taller.
• Leaves: Small, often narrow or spoon-shaped, brightly variegated in combinations of red, burgundy, orange, yellow, pink, and green.
• Flowers: Tiny, papery, whitish flowers that are insignificant.
• Form: Dense and bushy; tolerates shearing into tidy shapes.
• Texture: Some cultivars have ruffled or twisted leaves.

Light: Full sun to bright indirect light; brighter light intensifies leaf color.

Water: Keep soil evenly moist; do not let it dry out fully.

Soil: Rich, well-drained soil or quality potting mix.

Temperature: A warm-climate plant sensitive to frost; bring indoors or treat as an annual in cold regions.

Feeding: Light, regular feeding supports lush, colorful growth.

Propagation: Very easy from stem cuttings, which root quickly. Shear or pinch to maintain shape and density.

Native to tropical Central and South America, where it grows in warm, moist, sunny habitats.

Grown worldwide as a tender bedding plant for carpet bedding, edging, and containers, and as a houseplant in cooler climates where it cannot overwinter outdoors.

Ornamental: A classic foliage plant for low edging, intricate carpet-bedding patterns, knot gardens, and container accents.

Indoor color: Makes a compact, colorful houseplant in a bright spot.

Design: Its bold leaf colors provide contrast and structure without relying on flowers.
