Description

Hackelia brevicula is a perennial herb 20 to 60 centimeters tall and coated thinly in stiff hairs. Most of the leaves are located around the base of the plant, reaching up to 18 centimeters long; there are a few smaller leaves on the stem itself.[2]

The inflorescence is an open array of branches, each a coiling panicle of flowers. Each flower is just over a centimeter wide with light blue lobes with white appendages at the bases. The fruit is a cluster of nutlets which are often prickly. The bloom period is July.[2]
