About
Astrantia 'Berendien Stam' is a robust, clump-forming perennial characterized by its finely cut, mid-green foliage. The plant produces branched stems topped with dense clusters of mallow-pink blooms, which are encircled by white bracts with green tips. This flowering typically occurs in late June, and if pruned after the first bloom, a second wave of flowers can emerge in late summer.
