Astrantia Superstar Also known as Astrantia White Giant, Astrantia Superstar certainly lives up to its name – it’s tall, with really big flowers. It’s a clump-forming herbaceous pe rennial with palmate (like a hand) deeply lobed, deep green, basal leaves, a wonderful foil for the flowers. From June to September, branched, green stems rise above the basal clump bearing large, starry, pincushion-like pure white flowers tipped with green, and touches of crimson in the ‘pincushion’. It is not unlike that excellent old cultivar, Astrantia Shaggy. Deadhead to keep the flowers coming; cut back in late autumn, and mulch in early spring to conserve moisture.
