Geranium malviflorum is a broadleaf deciduous perennial with green foliage. In spring purple flowers emerge. Grows well with sun and regular water. Does well in average and well-drained soil.
We acquired this incredibly tough, tuberous, summer dormant Geranium in the 80's from East Lambrook in southern England which was home to Margery Fish and the original English Cottage Garden. Provenance alone is merit enough but good lavender blue flowers and drought tolerance carries the day.
