Senna pendula, widely known as Christmas senna, is a fast-growing, semi-scandent shrub celebrated for its exuberant winter display of golden-yellow blossoms that often peak around the holiday season, giving rise to its festive common name. This South American species develops long, arching to pendulous branches clad in pinnate leaves composed of smooth, oval leaflets that impart a soft, airy texture to the plant. During its extended blooming period—most pronounced in late fall and winter in warm climates—it becomes smothered in loose clusters of five-petaled, butter-yellow flowers that serve as a valuable nectar source for bees and butterflies at a time of year when floral resources may be limited. Slender, slightly curved seed pods follow the blooms, maturing in abundance and contributing both ornamental interest and the plant’s tendency to self-sow readily. Adaptable to full sun, heat, and poor soils, Christmas senna is prized for its low-maintenance vigor, drought tolerance, and ability to form bright, informal hedges or screen plantings. With its graceful habit, sunny coloration, and reliable seasonal performance, Senna pendula offers a dramatic splash of winter brightness in subtropical and tropical landscapes.
