Geranium ‘Summer Skies’ is a clump forming perennial that is hardy in the UK. The flowers are pastel coloured doubles with yellow centres . Tiny central petals form a distinctive, open bowl shape. You’ll see the base colour described as sky blue (sky-blue pink is, for once, more accurate); the colour tends to deepen as the flowers age. Dissected foliage and branching stems complete the picture.
The overall effect is ethereal – if fairies were cavorting in and around geraniums, these would be the ones they’d choose.
I love the hardy double geraniums, but have found the ones I’ve grown to be less resilient than their single cousins, with more of a tendency to be swamped by something. I’ve never grown this one, but it might be wise to keep it away from anything particularly invasive.
