Trianthema

Trianthema is a genus of plants in the family Aizoaceae, which is native to southern Africa. The genus is characterized by its succulent stems and leaves, and produces small, fruit-like structures that resemble tomatoes, hence the common name trigonella or trianthen.

The plants of this genus are small and herbaceous, typically growing between 10-30 centimeters in height. They have a small rosette of leaves that are often succulent and may have waxy, chalky coatings on the surface. The flowers are small and inconspicuous and are typically yellow, but may also be orange, red, or white.

Trianthema species are found in a variety of habitats, including grasslands, savannas, and coastal areas. They are well adapted to hot, dry environments and play a role in the ecosystem as food sources for herbivorous animals. The genus is also used in horticulture and is popular among succulent enthusiasts.

Some species within the Trianthema genus are prized for their unusual growth habits and attractive flowers. For example, Trianthema sericea, found in South Africa, has a silky, soft leaf surface, while Trianthema pirica, found in Namibia, produces bright orange flowers.

Trianthema has been used in traditional medicine for various purposes, including as an antidote for snake bites and as an abortifacient. While no comprehensive studies exist on the efficacy and safety of its uses, it is considered to be potentially toxic and should be used with caution.

Care and cultivation of Trianthema species in cultivation involves providing these plants with high light levels, well-draining soil, and infrequent watering. They can be grown indoors as houseplants, but also excel in outdoor, dry environments.
