Among several varieties of japanese anemones that I have, 'Whirlwind' is easily the most vigorous performer. Grew over 4 feet already in the first year, with fantastic semi-double white flowers. Grown in semi-shade in my garden (zone 5b/6a), it's much taller than usually listed. This is one of rare cultivars among the most popular japanese anemones that originated in the US. An heirloom hybrid dating from 1887, bred by James Vick and Sons from Rochester (NY).
