9 cm sized pot.  Potentilla nepalensis "Ron McBeath" is a hardy perennial with bright pink flowers with a dark centre held on long stems above green textured, soft strawberry-like foliage.  Likes a sunny position in well-drained soil.  Loved by bees.  Flowers reaching 40-50cm tall.  A cut back in late summer may provide you with another flush of flowers in late autumn.
