Amianthium muscaetoxicum flower

Flowering - May - July.

Habitat - Mesic upland forests, lower slopes of ravines, north-facing slopes. Typically on acid substrates.

Origin - Native to U.S.

Other info. - This striking species can be found mainly in the most southern counties of Missouri but a few disjunct populations are found in counties along the Missouri River.
The plant can be identified by its long, thin basal leaves, and its dense, cylindrical inflorescence of many small, white flowers. The pictures above were taken in a recently burned pine-flatwoods so the basal leaves of the plant were missing. Also, the plant pictured above is shown very early in its flowering stage. The inflorescence gets much longer and more cylindrical with time. The flowers also typically change from white to yellow or even purplish with age.
A. muscaetoxicum is a toxic species which contains many alkaloids. Cattle have been killed from eating the plant.
An alternate spelling is Amianthium muscitoxicum.
