A low growing perennial Geranium 'Rozanne' is excellent as a front of border plant and as a spiller for the edge of pathways - like most perennial Geraniums once it goes past flowering, give it a good trim back and you'll get a secondary flush of fresh foliage - making the whole thing a tidier plant.
And after all...its nice to have an award winning Chelsea Flower Show plant in your own back garden!!
