Castor bean plant - Ricinus communis
The castor bean plant is an amazing annual that grows anywhere from 2 to 5 metres tall. Plants frequently need staking. Castor bean seeds are highly poisonous, so keep children and pets away from seedpods. Sap from seeds and the plant may cause an allergic reaction, so handle seeds with care. Wearing gardening gloves will help prevent any reaction. Wash hands thoroughly after touching the plant. Seeds
Sow castor bean from seed either outdoors directly in the soil after all danger of frost has passed or indoors six to eight weeks before your region's last average frost date. Soak the seed for 24 hours in warm water, then plant it 1 inch deep. Castor bean needs rich, deep, well-drained soil and prefer full sun. Trim faded flowers to promote longer bloom.
The seed pod is composed of three sections or carpels which split apart at maturity. Each section contains a single seed. The seeds have very interesting patterns, with no two the same. At one end is a small, spongy part called a carnucle, which helps the seed absorb water. Print a seed label for castor bean seeds.
