While the foliage of snakeroots can be stunning, many gardens do not have enough space for them to extend their sprawling flower stems. Now that rich burgundy-cocoa sheen is available in a tidy package, “Chocolate Shogun” Astilbe. Diminutive even by astilbe standards, its foliage reaches a mere 15″ above which it sends creamy pink plumes of bloom. Grows in all of the standard astilbe locations.
