Arresting pop-poms of dark crimson cover this delightful plant for months.
It spreads out from a central rootstock into a many branched bush, each shoot keeps branching to form a wiry network of stems. Every shoot and side-shoot produces a flower.
Rather than deadhead, cut down old stems allowing newer stems some room.
They do have a tendency to sprawl so staking will improve their appearance.
In common with all plants of the Scabious genus they are an important nectar source for pollinators. Leave the seed heads on throughout winter for small birds to feed on.
