About Alternanthera

Alternanthera (Alternanthera dentata) is a tropical perennial from South America grown as a warm-season annual in Northeast Florida for its vivid burgundy, chocolate-red, or purple foliage. Its compact, mounding habit and intensely colored leaves — best in full sun — make it a staple for tropical bedding displays, borders, and container combinations from spring through first frost. Starting at $6.95.

Care essentials

Light

Plant Alternanthera in full sun for the most intense foliage color; it tolerates part shade but colors become muted. Northeast Florida's full summer sun is ideal for this tropical foliage plant.

Water

Water regularly to maintain evenly moist soil; avoid letting plants wilt, which dulls foliage color. Mulch around the base to retain soil moisture and reduce irrigation frequency in Florida's sandy soils.

Soil & Fertilizer

Performs well in sandy to loamy, well-drained soils. Feed monthly with a balanced fertilizer during the growing season to sustain vigorous color; pinch tips regularly to maintain a compact, bushy form.
