Fun Facts

🌱 Croton Zanzibar's leaf colors intensify dramatically with increased light exposure; plants grown in low light may appear predominantly green, while the same plant in bright light displays striking reds, oranges, and yellows.
🌱 The name 'Zanzibar' refers to the Zanzibar islands off the coast of Tanzania, though this variety's exact origin is likely hybrid cultivation rather than native Zanzibari provenance.
🌱 Crotons produce a milky sap that can irritate skin and is toxic if ingested; always wear gloves when handling or pruning, and keep away from children and pets.
