Astrantia ‘Star of Billion’

White Masterwort

USDA Zone: 3-9

Plant number: 1.088.390

Masterwort is a real workhorse in the garden, flowering for a good part of the summer. It features branching umbels of pincushion flowers. This midsized selection has white centres surrounded by white bracts with green tips. Nice in mixed containers or tubs. Flowers may be cut fresh, or dried for winter arrangements. Remove faded flowers to encourage more buds, also to prevent plants from self seeding all over. USPP#20352: unlicensed propagation prohibited.
