A hairy annual (the other Woundworts are not annual) growing to 25cm, much shorter than most other Woundworts. Stems are weak and spreading, but sometimes erect.

Leaf teeth are crenate (half-rounded)

The lower lip is much shorter, perhaps because it is a younger specimen? Although the leaf teeth are rounded, some have a point at the tip.

Stem is square with sometimes downwardly angled hairs. Flowers in single-layer whorls around the stem with only up to 6 flowers in a whorl. Upper leaves narrower than lower leaves. [The parachute seed of different plant has caught itself in this hairy plant]

Sepal teeth are long. The corolla is a dull purplish-pink and with ostensibly 4 petals, an upper petal, and 2 side lobes adjoining a longer lower lobe, which may or may not have a slight nick at the end (which might make '5' petals). The lower petal does get slightly longer than in these specimens, but it is never on a par with the length of those on Hedge Woundwort or Marsh Woundwort.

You can just espy two cream-coloured sexual organs peeping from the top petal.

The books say that Field Woundwort is without glandular hairs, but there are some on the sepal teeth of this one (unless it's dirt?). However, most hairs are just plain.

Lower leaves are wider and more oval to olanceolate to cordate (heart-shaped), with more rounded teeth.


Some similarities to : Marsh Woundwort (Stachys palustris) but the corolla of that is pinkish purple rather than dullish-pink. And to Corn Mint (Mentha arvensis) which also grows in arable land but that has whorls which are in several stacked layers and a slightly minty odour.

Slight resemblance to : Hedge Woundwort (Stachys sylvatica) but that has petals of a much deeper red-purple.

It grows in arable fields on either acidic or neutral soils but not on calcareous soils. The flowers, at 6-8mm, are about half as long as those of other Woundworts. Also, it does not have an objectional smell, if any aroma it has(?).
