Geranium Johnsons Blue ground cover is a fantastic variety, bearing masses of large, dark-veined, lavender-blue flowers from May to August that fade to soft pearl grey as they mature. A slightly sprawling plant that looks best when allowed to spread freely, rising from vibrant green foliage. These hardy plants are ideal for suppressing weeds at the front of a mixed or herbaceous border and will keep your bees and other pollinators happy for months!
Geranium Johnsons Blue are vigorous plants with a spreading habit and tolerate heat better when in part shade. They make superb ground cover but are incredibly versatile and are equally happy in pots, troughs or trailing over tubs. Perfect for planting in rose gardens and wildflower planting schemes, or in perennial borders in cottage gardens. Try planting in a mixed border with Salvia, Eryngium and Agapanthus.

Super low maintenance, as a ground cover plant Geranium Johnsons Blue (Cranesbill) will tolerate any soil other than waterlogged areas and will be happy in full sun or partial shade. In midsummer rejuvenate plants that are beginning to look jaded, by removing old, flowered stems and leaves, and split the clumps in spring if they are getting too large.
As a rough guide when planting Geranium Johnsons Blue as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
