Sometimes known as succulent sesame, Uncarina is a striking shrubby plant, large enough to be considered a small tree in its native Madagascar. Uncarina is an otherworldly-looking plant with a swollen, succulent base, thick, twisty branches and fuzzy leaves. If this smattering of Uncarina information has piqued your interest, read on to learn more about growing Uncarina and caring for Uncarina plants.

Uncarina Information

The color of Uncarina blooms, which vary depending on the species, ranges from various shades or orange-yellow or golden-yellow, or even purple or rose. One popular species, Uncarina grandidieri, produces bright yellow blooms that resemble petunias with contrasting dark throats. Similarly, the shape of the leaves depends on the species.

Uncarina is also known as claw plant or mousetrap tree for a very good reason – the seed pods are armed with stout, hooked barbs that frequently grab unsuspecting animals unlucky enough to pass by. If you’re daring enough to try growing this unusual, somewhat eerie plant, don’t touch the pods, as the barbs are extremely difficult to remove from fingers.

Growing Uncarina Plants


Uncarina is a deciduous shrub that can be grown in a container, or in the ground where is can reach heights of 10 to 12 feet. If you opt to grow Uncarina in a container, a smaller pot will keep growth in check.

Propagating Unicarina is done via cuttings or seeds.

Caring for Uncarina Plants

Uncarina plants require plenty of bright light, although the plant will tolerate light shade when grown outdoors in sunny climates. Uncarina requires well-draining soil; indoor plants do well in a potting mix formulated for cactus.

Uncarina care is uninvolved, as Uncarina is relatively drought tolerant once established. It benefits from regular water during its growing period, but should be kept dry during winter dormancy. This tropical plant won’t tolerate frost.
