A pretty vigorous, perennial that forms a matt of bright green leaves, which are hay scented when dry. Clusters of small white flowers are produced in Spring. I cut mine back after flowering to encourage another burst of blooms.
Likes any moist well drained soil in partial shade.
Great for underplanting in borders and wildlife gardens. Good for pollinators.
Height 10cm-50cm x Spread 1-1.5m
