Salvia somolensis

Sorry no photo.  This is a beautiful salvia from Somalia in East Africa. It had highly aromatic foliage that grows into a large bush up to 2m but most gardeners would keep it trimmed to 1m. It can be slow to flower (as I have found) but when it does the lime green foliage setd off the pale blue flowers to perfection. The bottom lip of the flower is marked with white, Drought resistant and frost hardy with me.
