About

Catalpa ovata is a medium-sized tree characterized by its broad, rounded canopy, typically growing to a height of around 10 meters. The leaves can measure up to 25 centimeters in length and are pale green with a broadly oval shape, frequently exhibiting three lobes. During mid to late summer, the tree produces substantial, upright clusters of cream-colored, bell-shaped blooms, featuring orange and purple markings within the throat. After flowering, it develops elongated, slender pods that hang down, resembling beans.
