The number of poisonous plants found in homes and gardens is shocking. House plants like dumbcane and castorbean, and outdoor plants like hollies, irises, and oleanders are toxic and found in many gardens.The North American Guide to Common Poisonous Plants and Mushrooms is a comprehensive, easy-to-use handbook. The book is split into four main categories: mushrooms, wild plants, ornamental and crop plants, and houseplants. Each plant entry includes a clear photograph to aid the task of identification, a description of the plant, notes on where they commonly occur, and a description of their toxic properties. Plants are listed by common name to assist the non-specialist.
