Germander speedwell is a perennial plant that grows up to 50 centimetres tall. It has narrow, opposite leaves that are toothed and hairy, and hairy stems. It has a fibrous root system and creeps along the ground, spreading by sending down roots at the stem nodes. The flowers are blue or violet, each with a white eye. The flowers are hermaphrodite (have both male and female reproductive parts) and are pollinated by insects. The mature fruit is a heart-shaped capsule.
Commonly found in grasslands, woods and hedges and on scree slopes, it is widespread throughout Europe with the exception of the far north.
