The lavender-blue flowers of Geranium pratense \'Plenum Caeruleum\' rise above the lacy foliage in early summer. This hardy Geranium is a reliable variety that makes fabulous ground cover when planted in groups. It’s loose, spread habit and finely-cut leaves will spill from the edge of borders to gently soften path edges and create that lovely cottage garden feel. A superb addition to the garden, which requires very little maintenance. Height: 70cm (28). Spread: 45cm (18).
