Leaves and stem
This is a perennial plant that has creeping stems. These send out roots at regular intervals, and upright flowering stems. The leaves and stems are hairy, giving the plant are ‘soft / gentle’ feel.
The leaves are roughly rounded or kidney shaped, with a toothed margin. They are a dull, dark green colour. They may be up to 4 cm in width. Each leaf has a distinct (and often long) leaf stalk or petiole. The plant has a pungent smell - especially if the leaves are crushed.
Flowers and Fruits
The flowers are purple / blue / violet in colour and form in the axils of the leaves. The calyx (sepals) is toothed, and the corolla (petals) is in the form of a tube - with ‘lips’.
The lower lip has three lobes (see adjacent image). Four stamens are present, and white hairs are visible on the lower lip. Flowers are formed from March through to June (generally).
