Anemone japonica is able to hold its own if combined with other assertive plants like Amsonia hubrichtii, named Perennial Plant of the Year in 2011. And the partnership couldn't be more pleasing, the Amsonia's foliage turning a striking gold in fall and providing the prime example of accessorizing when grown near fall Anemone.
A little more tricky to find partners for, but no less welcome in the late fall garden is Dendranthema 'Sheffield Pink'. The color portion of the moniker is not quite correct, however, as the flowers open in shades of pinkish-apricot. Still, it's gorgeous with the small-flowered asters like 'Little Carlow', a hybrid between cultivars of Aster cordifolius and Aster novi-belgii. I've been growing 'Little Carlow' for several years, and I fall in love with it each time it blooms.
Nonetheless, it's certainly worth seeking out, because those in the know know to grow 'Little Carlow'.
