Botanical name: Eupatorium cannabinum
Folk names: Raspberries and cream

Type: Perennial

Wildlife: Accessible nectar for a range of insects including hoverflies, and butterflies including the small tortoiseshell and red admiral. (Kate Bradbury finds this plant more popular with butterflies than buddleja.) Two species of hornet mimic hoverfly spotted foraging on it in Richard James’ Oxfordshire garden in July 2026.

Flowers: July to September

Decorative merit: Frothy pink-mauve flowerheads made up of tiny tubular florets, on reddish stems with trifoliate leaves. Forms a bushy plant up to 1.5m tall.

Where: Marginal area next to a pond / bog garden, moisture-retaining border in shade or part-shade. Deadhead to main flowerhead to prolong flowering and do a part ‘Chelsea Chop’ before that (thanks for the tip, Richard!).
