Datura stramonium

Southern Illinois University

Jimsonweed is a common plant found in gardens, fields, roadsides, and waste places.

It was introduced from Asia, but has spread rapidly.

Jimsonweed can be recognized by its purplish-green stems and its large toothed leaves.

The flowers of this plant smell sweet, but otherwise Jimsonweed has a general bad odor.

Jimsonweed is an annual, which means it lives for one season, then dies.

The flowers of Jimsonweed are long, tube-shaped, and pale lavender in color. They can be up to four inches long.

Each flower opens wide at night, then drops off the plant in the morning. Flowers attract bees, moths, and butterflies.

Jimsonweed fruits are spiny capsules filled with many black seeds.

These plants often fall over from their own weight.

Jimsonweed is not eaten by mammals, because it is poisonous. Some insects will eat leaves, and moths will visit flowers frequently at night for nectar. Hummingbirds also drink nectar from flowers.
