About

Red bartsia is a common plant of roadside verges, railway cuttings, waste ground and other disturbed ground. These areas often have low-fertility soils, so Red Bartsia is actually partly parasitic, gaining extra nutrients from the roots of its nearby host grasses. As its name suggests, the whole plant is tinged with red; its leafy flower spikes appear from June to September.

What to look for

Red bartsia is a straggly, downy plant with narrow, toothed leaves that sit opposite each other along the stems. Pinky-purple flowers appear on the stems in clusters, nestling in the leaf axils (where they join the stem).

Where to find

Widespread.
