Keep an eye out for weeds that have purple-spotted stems and white, umbrella-like flowers:

Poison hemlock has made its way to all 50 states, including Rhode Island, except for Alaska, Florida, Hawaii, and Mississippi, so it’s something we’ll all likely deal with at some time or another.

Commonly found in yards and fields, on the sides of roads, and near waterways, poison hemlock is easy to spot. Towering between six and 10 feet, the deadly weed sports purple spots on the stem and white flowers that resemble a tiny umbrella.
