This low-growing, mound-forming evergreen groundcover is native to tropical regions from the West Indies to Brazil. Alternanthera dentata or Joseph's Coat features ornamental foliage displays of a multitude of colors such as purple, burgundy, red, pink, orange, yellow and green on small plants 2-5 ft tall. Not only does this plant add an eye-catching contrast to gardens, but it also needs minimal care and maintenance.
Full sun is recommended for Alternanthera dentata to maximize its colorful foliage and blossom white or off-white flowers. Semi-shade is also acceptable, but try to avoid full shade. Water regularly, but not in excess to prevent waterlogging and ensure that the soil doesn't completely dry out.
Zones 10-11 USDA are ideal for growing Alternanthera dentata, but those living in cooler climates can still enjoy this plant with a few extra steps. Pot your Alternanthera dentata in a pot that can be moved indoors during a frost. Mature cold-hardy at least to 30s F for a short time, this beautiful tropical plant is also salt tolerant and makes for a great choice for seaside gardens.
With its stunning, long season of color and low-maintenance requirements, Alternanthera dentata or Joseph's Coat is a fantastic choice for gardens, landscapes and container plantings.
