Harperella - Endangered Species

Harperella (Ptilimnium nodosum)

Harperella (Ptilimnium nodosum)


Harperella (Ptilimnium nodsoum) is a rare and endangered perennial herb that grows to a height of 6 - 36 inches. It is also known as Bishops Weed. It comes from the carrot family. It smells similar to dill weed. This plant is found in the rocky swift waters of Little River.

The leaves are hollow, quill-like structures. The small, white flowers have five regular parts. The small white flowers grow on top of the stems and bloom from May until frost. They reproduce when the water is low; the seeds fall into the crevices of the rocks and germinate. The roots take hold and stay underwater or at least wet until the plants bloom in late May.
