Christmas bush, also known as Winter cassia, Yellow candlewood, Rambling senna

Christmas bush is characterized by its semi-evergreen nature, primarily presenting as a shrub or small tree with an upright growth habit.

Christmas bush features pinnately compound leaves with distinctly alternate leaf arrangement. Each leaf comprises three to five pairs of dark green, obovate leaflets that are about 1.5 inches (3.8 cm) long. The leaflets are oval-shaped and taper towards the base, creating an obovate form. A smooth texture characterizes the leaflet's surface while the vein pattern is prominently visible, contributing to its structural integrity. These key features are essential in identifying christmas bush.

Fruit Features

The fruit of christmas bush is a distinctive brown slender pod, notable for reaching lengths of up to 6 inches (approximately 15 centimeters). The pods are slightly curved and offer a smooth yet firm texture. Upon maturity, they may exhibit a slight sheen on their surface. These pods characteristically split open into two halves, revealing several seeds that are crucial for the plant's reproductive cycle. These seed-housing compartments are a key feature for identification, as they uniquely encapsulate the seeds in a singular linear arrangement.
