Anemone 'Whirlwind' is a late summer bloomer producing large semi-double white flowers. It is not an aggressive grower in our garden but will spread slowly to form a nice clump. It is best siuated in morning sun in a sheltered location.
Anemone 'Whirlwind' likes sun to partial shade in good soil that has been enriched with a little compost. It is on the edge of hardiness in our area so provide a sheltered spot for it, mulch it well and do not expect rapid growth from it.
