Plant details

Highly effective at the front of a border where its floppy, trailing stems make good ground cover the 'Arc-en-ciel' stands out thanks to the large, dark red flowers with a flash of yellow at the edge. The main flowering period is June, July and August, but the moment it stops, cut it right back to get a second flush of leaves and buds. The ground must be free-draining or it won't survive winters in damp, cold soil. Can also be grown in rock or gravel gardens or containers.
