The stems are branched and have fine hairs. The leaves are opposite, ovate-oblong, and serrated on the edges. In summer, it produces pale red-purple flowers with four petals.

It produces racemes at the top of the stem, with many beautiful red-purple flowers. It can form large colonies after forest fires.
