Christmas senna is a small shrub native to Tropical America. Demonstrating one of its hardiest characteristics, the plant typically grows 2-5 feet tall, with evergreen foliage and an abundance of yellow, orange flowers. Though Christmas senna can tolerate full sun, it prefers semi-shade, and will most likely experience full flowering potential when planted in dappled to full shade, with regular to moderate water. Though the plant can not tolerate cold, it does still perform in colder climates as long as it is kept in a pot, providing the roots are kept warm.
Christmas senna is often referred to as one of the most beautiful flowering plants. As such, it's an ideal choice for attracting hummingbirds and butterflies as they flock towards the bright and vibrant colors of its blooms. But, if you want to enjoy the beauty of this species, frequent pruning and pinching of the young shoots are necessary during the growing season to encourage branching and ensure a successful bloom. And, while larger specimens may require staking to keep them upright, the effort put into tending to Christmas senna is truly worth it. The tall and brightly colored blooms of this delicate flower will transform any outdoor space into one of tranquility and beauty.
Christmas senna is best grown in USDA Zones 9-11, and as long as you satisfy its needs for semi-shade, regular to moderate water, and warmth in colder climates, you can enjoy its beautiful, yellow and orange blooms for years to come.
