A comprehensive introduction section explains their botany and classification to help the reader distinguish between the many classifications and families. Each variety featured in the directory is provided with information about growth, spread, size, flowering and habitat. With over 1000 colour photographs, this is a useful reference for gardeners to the world of cacti and succulents.
