About plant names...

Northern willowherb is named for the lacy tuft of white hairs that surrounds its seeds. It is native throughout most of North America, along with eastern Asia. It also prospers in Eurasia and Australia, where it was introduced as has become naturalized.

Identification: Plants are between 4-6' (1.2-1.8 m) in height. Leaves are up 6" (15 cm) long at the base, narrow, dark green or reddish, with deep sunken veins. Flowers are pink, trumpet-shaped, with four petals, each separated into two lobes. Petals are often darker pink at the edges. Sometimes the flowers are white or cream-colored. They are about 1-4" (3-10 cm) long.
