Cranesbill. This plant was awarded RHS Plant of the Century at Chelsea 2013. A favourite of mine as it is easy care and flowers its head off from summer to autumn. Attractive grey-green foliage and loose clusters of long lasting mauve blooms. Likes sun or part shade and well drained soil.

If necessary during the long flowering period of 'Rozanne' you can give the plant a light trim all over to reinvigorate. It bounces back very quickly.
