Cabomba Caroliniana originates from the subtropical temperate regions of northeastern and southeastern America. The species has two variants with different distributions. The variety with purple flowers, Caroliniana, occurs in the southeastern United States, while the yellow-flowered variety, Flavida, is found in South America. The trade of these plants in the aquarium industry has led to their introduction in areas outside their native range.
How to Grow and Care for Cabomba
This plant has broad ecological requirements. It is often rooted in muck in streams, rivers, and lakes with gentle water movement. It can grow in water with a pH value ranging from 5.7 to 9.2. Its growth is highest at moderate water turbidity, but the plant can still thrive in highly turbid water. Cabomba caroliniana prefers a warm subtropical climate with temperatures ranging from 13 to 27 °C, although it can tolerate temperatures below freezing. In China, the plant is particularly aggressive and problematic in nutrient-rich waters.
Cabomba caroliniana is a perennial species that produces solitary hypogynous flowers with three sepals, three petals, and six stamens. The flowers have a diameter of 1-2 cm and come in white, yellow, pink, to purple-lilac colors. The flowers are bisexual and often self-pollinating. However, vegetative reproduction is likely the most important way this plant spreads. It produces rhizomes that can easily break into fragments. Fragments can be transported actively or passively to new areas. A fragment can regenerate into a full plant as long as it carries at least one pair of leaves.
