Foeniculum vulgare 'Purpureum' - Bronze-leaved Fennel - Cotswolds Grown Culinary Herbs

From midsummer, it produces flat heads of yellow flowers that contrast strikingly with the dark stems. Both ornamental and edible, this variety brings height, movement, and a rich colour palette to borders while attracting a wide range of pollinators.

Foeniculum vulgare ‘Purpureum’, commonly known as Bronze Fennel, is prized for its soft texture, architectural shape, and culinary uses. It’s equally at home in wildlife gardens, herb beds, or modern borders.
