Plant Profile: Allamanda cathartica

Allamanda cathartica, commonly referred to as Allamanda, is a genus of tropical, tender, perennial evergreens. This genus comprises 15 species native to South and Central America, and they are frequently cultivated in gardens across tropical regions, where some varieties have become naturalized and even invasive. In temperate regions like the United States, Allamanda is typically grown as a greenhouse or houseplant, prized for its abundant, vibrant golden yellow flowers that beautifully contrast with its glossy dark green foliage.

Allamanda typically grows as a sprawling shrub or woody climber, often requiring support as it tends to spread and entwine around structures. When cultivated outdoors, these plants should be pruned and brought indoors as container plants before the first frost. It is essential to place them in a location with bright light once inside. Regardless of whether they are indoors or outdoors, Allamanda plants need sufficient moisture and well-draining soil to thrive.

Regarding plant health, there are currently no known diseases or insect pests affecting Allamanda.
