About Castor bean
Ricinus communis, commonly known as Castor Bean or Castor Oil Plant, is a fast-growing annual or perennial plant, valued for its exotic foliage and striking seeds. Its large, palmate leaves, often in shades of red or purple, give it a tropical appearance that looks spectacular as a focal point in large gardens or as an accent plant in big pots.

Care tips
It requires full sun exposure for optimal growth and intense leaf coloration. Watering should be regular, keeping the substrate moist but not waterlogged, especially during dry periods. It prefers rich, well-drained, and slightly acidic soils. A common mistake is underestimating its toxicity; all parts of the plant, especially the seeds, are poisonous if ingested, so it must be handled with caution, especially around children and pets.
