Uncarina grandidieri, commonly known as Mouse Trap Tree, is a deciduous shrub or small tree native to the dry deciduous forests and spiny thickets of Madagascar. It can grow to a height of 8-12 feet (2.4-3.7 meters) and a width of 4-5 feet (1.2-1.5 meters). The Mouse Trap Tree has a distinctive appearance with a thick, succulent stem and large, heart-shaped leaves. It produces showy, bright yellow, trumpet-shaped flowers with a dark throat throughout the spring, summer, and fall, which are highly attractive to pollinators.

In cultivation, Uncarina grandidieri is valued for its unique aesthetic and its ability to thrive in arid conditions, making it suitable for xeriscaping and as a specimen plant in succulent gardens. It requires full sun to flower profusely and prefers well-draining soil. While it tolerates low water conditions, moderate watering will support better growth. It is not commonly used in large-scale plantings due to its rarity and specific growing requirements. Gardeners should handle this plant with care, as it has hook-covered fruit that can cling to animal fur and clothing. It is also important to note that all parts of the plant are toxic if ingested.CC BY-SA 4.0
