Geranium espresso from Sarah Raven.
The flower is 1/2 in = 12mm across. Tiny.
Fine sunny day with great progress on the dyke CK and rocks / shifting rockery me.
The gardener slaved on all round magnificently and heroically as usual such progress in a short time will be able to open to the public next year at this rate.
Many thanks to loisbiz for hosting Tiny Tuesday.
