Summer Plants
These seasonal plants pose the most severe hazard to your health if consumed in certain quantities:
Larkspur—A garden staple, these cheerful perennials can cause adverse neurological and cardiac effects.
Foxglove—Beloved for its bell-shaped flowers, these tall plants can slow your heart rate and cause confusion.
Cotoneaster—A popular groundcover, the seeds and berries break down into cyanide when consumed.
Other plants are only harmful if consumed in large quantities:
Allium—Also known as wild onion or garlic, large amounts of this bulbous plant can upset your stomach.
Tomato and Potato—If consumed before proper ripeness, these plants can lead to nausea and vomiting, as can the leaves (regardless of ripeness).
Pokeweed—The berries on this shrub resembles blueberries, but consuming too much can cause significant gastrointestinal problems.
Black-eyed Susans—This common prairie plant can irritate the skin upon contact.
IPC suggests admiring all plants from afar if you aren’t sure of a plant’s identity.
