Stachys recta, commonly known as stiff hedgenettle or perennial yellow-woundwort, is herbaceous perennial plant of the family Lamiaceae.
The biological form of S. recta is hemicryptophyte scapose, as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect with a few leaves.
The plant reaches on average 20–40 centimetres (7.9–15.7 in) in height. It has thick, woody roots. The stems are strong, simple or branched, with slightly rough glandular hairs. The leaves are ovate-spatulate to oblong-lanceolate, with toothed edges and a long petiole. The length of the leaves is 3–5 centimetres (1.2–2.0 in) and the width 0.5 to 2 cm. 5–20 millimetres (0.20–0.79 in).

How to get rid of:
The fibrous root system of perennial plants can be several times the size of the aboveground plant, and may require more digging to get as much of the root system as possible. If you can return to the site, you can allow resprouts to reveal the position of any surviving roots. They will likely be easier to pull then and it could save a lot of digging and sorting through the ground.
