Description

Hempnettle is an annual up to 4-8 dm tall with hirsute square stems. Multicellular hairs cover the stem and become mixed with glandular hairs below each node. The nodes are widely spaced and swollen. The opposite leaves are petiolate with ovate to lanceolate blades that are hirsute above and pubescent below. The white-to-pink flowers are sessile in dense verticels. The corolla is strongly two-lipped, the upper lip being erect, entire, and the lower lip being three-lobed and bearing two protuberances at its base. The fruit is a brown nutlet with tan mottling.

Interesting facts

Hempnettle is found in fields, gardens, roadsides, waste places, forests, and moist places along streams.

Hempnettle seeds germinate and grow rapidly under warm conditions, thus they may be a serious problem in crops requiring similar conditions for germination and growth.
