How to Grow and Care for Castor Bean

The castor bean is important for its oil which is used as a lubricant, biodiesel ingredient, and rodent repellent, among other applications. The plants are now commercially planted globally, with India producing nearly 75% of the world's castor oil. Castor beans cannot be eaten because they contain a potent poison that's released if the seed is broken.

Castor bean 'Carmencita' boasts vibrant red foliage, which is complemented by its striking, spiky seed pods. Under full sun and in well-draining soil, castor bean 'Carmencita' can grow rapidly into a bushy shrub. The plant uniquely develops both star-shaped flowers and bold, ornamental leaves, which serve as a beacon for pollinators while acting as a deterrent for pests with its toxic seeds.
