The flowerheads are enhanced by a central boss of yellow stamens, creating a delicate contrast against the plant's handsomely lobed foliage.

How to care for Anemone × hybrida Whirlwind:
Cut back the stalks after the flowers have faded, and tidy up old dead leaves in March. Apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant in spring. Avoid moving the plant since it resents disturbance. Where necessary lift and divide congested clumps in early spring.
