Gordon Rowley opens the doors on what he calls "Teratopia" - a new name to cover the world of vegetable wonders and shockers such as fasciation, cockscombs and brain-like crests, and variegation in multi-coloured, striped and dappled forms. Cacti and succulents are more prone than others to sport into these weird forms. Gordon Rowley gives in-depth information on how to grow them and how to form a collection. The book is superbly illustrated with nearly 600 colour photographs. The main genera covered are Aeonium, Agave, Aloe, Ariocarpus, Astrophytum, Cereus, Cleistocactus, Copiapoa, Cotyledon, Crassula, Echeveria, Echinocereus, Echinopsis, Eriosyce, Euphorbia, Gasteria, Gymnocalycium, Haworthia, Kalanchoe, Lithops, Mammillaria, Opuntia, Pachypodium, Parodia, Rebutia, Sansevieria, Sedum, Sempervivum, Senecio & Turbinicarpus.
