Poisonous Plants and Their Look-alikes: Tell Dangerous Plants from the Ones They Imitate. United States & Canada

The plants that hurt people are rarely exotic.

They grow in ditches, along fence lines, and in the bed beside the back door. At a glance, they look like something you already know. That resemblance is where the trouble starts.

Poison hemlock and wild carrot share the same lacy leaves and the same flat white flower cluster. Death camas comes up in the same meadow as wild onion. Every spring, people fill a bag with what they believe are ramps.

This is a field guide built around that specific problem.

Hazel Whitaker has spent more than thirty years learning which plants are worth knowing and which ones will put someone in the hospital. What she offers here is a method you can run on a living plant, in order, before you decide anything.

Inside: eighteen chapters in four parts:

Emergency routing first: what to do if someone has already eaten, touched, or burned something, with poison-centre numbers for the United States and Canada Twelve high-consequence confusions, compared side by side: poison hemlock and wild carrot, the water hemlocks and the angelicas, death camas and wild onion, pokeweed and American elderberry, giant hogweed and cow parsnip, poison ivy and the plants mistaken for it An eight-character identification check you can run on an intact plant, with nothing to crush, taste, smell, or dig up Twelve more dangerous plants that have no convincing look-alike and still end up in the wrong hands: yew, oleander, castor bean, rosary pea, rhododendron, mayapple, and more Side-by-side character tables that mark every field mark as deciding, supporting, or not reliable alone Sixty licensed photographs and diagrams , placed where the comparison is actually being made Chapters on children, pets, and livestock , on removing or reporting a plant without making the exposure worse, and quick-reference decision tables for the field Written for the United States and Canada , with range and season noted for every comparison, because a plant that cannot occur where you are standing is not a candidate.

Naming a plant and being cleared to eat it are two different things. This book gives you a disciplined way to reach the first conclusion, and it is honest about where the evidence stops.

If you forage, garden, manage land, care for children or animals, or simply want to know what is growing around your home, put this guide where you can reach it before a familiar-looking plant becomes an emergency.
