How to Grow Korean Angelica
Angelica gigas
Korean Angelica is a dramatic biennial ornamental reaching 1.2-1.8m with deep purple stems and striking dark burgundy flower umbels in late summer. It forms a rosette of bold divided leaves in year one, then sends up dark purple-red stems topped with dome-shaped flower heads in year two before dying. Self-seeds freely in moist, partially shaded positions. Sow fresh seed in autumn as viability drops rapidly. An architectural statement plant for woodland edges and shaded borders.
When to Start
Direct sow outdoors as soon as soil reaches 5°C — typically early to mid spring. Hardy enough to tolerate light frosts.

Care Essentials
- A striking biennial ornamental grown for its deep purple stems and dark burgundy flower umbels. Unlike its culinary cousin A. archangelica, Korean Angelica is purely ornamental. It thrives in the same conditions, partial shade and moist rich soil, but brings dramatic colour to shaded borders. Let it self-seed to maintain a permanent colony despite its biennial lifecycle.
