Crotons – Codiaeum variegatum. Among ornamental-foliaged plants, few, if any, are more useful or beautiful than the different varieties of this genus (The British Encyclopedia of Horticulture) (1881) Crotons will grow in almost any well-drained soil but like most ornamentals, they prefer a soil with an acid reaction. It is in this preferred medium that they attain their maxium in leaf size and beautiful colouring. Dr. B Frank Brown (A Codiaeum Ecyclopedia – Crotons of the World).
