Rampion Seeds – Campanula rapunculus | Edible Herb & Perennial Vegetable

Rampion (Campanula rapunculus) is a fascinating dual-purpose plant — grown for both its edible roots and leaves, and its ornamental lilac-blue bell-shaped flowers. Once widely cultivated across Europe as a kitchen-garden staple, rampion offers spinach-like leaves and a parsnip-flavored white root that is harvested from October onward. A rewarding heirloom for edible landscapers and heritage gardeners alike.

Culinary Uses

• Roots: Harvest from October; used raw or cooked like radish or parsnip
