Book excerpt: If people knew how many poisonous plants are commonly found in homes and gardens, they'd be shocked. Plants as common as monkshood, castorbean, and oleander are not just dangerous, they're deadly. 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.
