Frankenia laevis

Sea heath, a low appressed shrub in the family Frankeniaceae. SW Europe, Britain to northwestern Africa, including Macaronesia. A garrigue specialist. Lovely plant with starry bright pink flowers and tiny little leaves. Rare but so hardy. This plant is discussed in the flora of Corsica, in the north at Cap Corse, where it survives on granite rocks sprayed by the sea in the incessant winds.  A bit further up you will find the Balearic eurphorbia, E. Pithyusa which is as tough as old boots. I’m now growing them together now.  Information from “Bring the Mediterraneanin to your garden” by Olivier Filippi. 5-10cm H, spreads happily.

It has been used as a lawn subsitute, although weeds do penetrate it, mind you they do in a normal lawn! Salt resistant. It can of course be planted with erigerons, smaller alliums, centaurea...
