Anemone tomentosa ‘Robustissima’;This is the easiest to grow, and hardiest of all the fall-blooming Anemone, with a vigorous, spreading habit and reliable late-summer display. Plants form a low mound of grape-like green leaves, with taller branching stems of soft-pink cup-shaped flowers. Divide in spring every couple of years to maintain control. Loves a rich, moist site. The fluffy seedheads have interesting winter effect.
