(Ricinus communis) The castor bean plant has been cultivated for centuries for the oil produced by its seeds. The plants themselves are very impressive. Their huge, lobed, star-shaped leaves can reach 3 feet in length. They look attractive in groups, or as individual specimen plants. Each plant grows very rapidly with little care or insect pests and produces a mass of lush tropical foliage. A great accent plant for any garden. 5 seeds/pkt.
