Gardeners' Notes:

My favorite astilbe, too. The extra height gives it more garden presence than most, and the deep color is great. The inflorescences are well branched and need no staking. I like the way they look even after they've finished flowering.

Like other A. chinensis forms, this is somewhat less drought sensitive than other astilbes---not that I'd ever plant it in a dry or sunny spot, but it's a little less inclined to get brown foliage in the heat of summer. Like all astilbes, this needs consistently moist soil and protection from hot afternoon sun---I wouldn't grow it here in eastern Massachusetts without irrigation.

This is by far my favorite astilbe, and I have at least a dozen different types planted in my yard. I have a cluster tucked slightly under my deck, receiving bright light but no direct sun. This area receives runoff from the house and deck but has good drainage - the soil stays fairly moist, but is not wet. The foliage is deep green, arching, and very fern-like. The flower stalks are about 24" and stay in color for weeks. They are quite dramatic!
