Eupatorium capillifolium, commonly known as dog fennel, is a tall, columnar foliage perennial grown for its intensely feathery leaves — each divided into segments less than 1mm wide — that are strongly aromatic when brushed. By autumn it can reach 2m, making it a striking vertical presence at the back of a mixed border or in a large container. Flowers are tiny and rarely seen before the first frosts cut the plant back, so it is grown entirely for its exceptional foliage.
Slightly tender — hardy down to around -5°C — it benefits from a sheltered position and a little winter protection in colder gardens but is easily propagated from cuttings as insurance. It performs best in moisture-retentive but free-draining soil in sun or partial shade. The intensely tactile foliage makes it a natural choice for a sensory garden.
