Astilbe 'Carminea' is a robust, clump-forming perennial that can reach heights of up to 90 cm. This variety features dark stems and deeply divided, dark to mid-green foliage. In late July and August, it produces elongated, narrow plumes of raspberry red flowers that can grow to 25 cm in length, rising above the leaves for an extended display.
