Geranium x pyrenaicum (Mountain Cranesbill)
Dainty little geranium which is useful for gravelled or paved areas as it likes to be in a dry situation and lends itself well to softening edges. Will seed itself around if it's happy. Small vivid purple blue flowers throughout the summer on this sprawling plant which rabbits and slugs avoid, are delightful. A bonus is that this plant is drought-resistant too. Ht 25-30mm spread indefinite.
