Alchemilla mollis 'Thriller' (Large Plant)

Lady's Mantle

This well loved perennial is a stalwart of cottage garden borders, with soft green, fan-shaped foliage that catches raindrops like twinkling jewels. Alchemilla mollis 'Thriller' is a more upright form than the species, with larger foliage and a clump forming, spreading habit. The clusters of lime green blooms are honey scented, attracting pollinating insects to their nectar rich, flowers. Commonly known as Lady’s Mantle, this low growing perennial makes a lovely border edging or a useful addition to wildlife areas and cut flower gardens. Height and spread: 50cm (20"). More info
