Seeds cardoon - Cynara Cardunculus

White Cardoon – Cynara cardunculus

Traditional vegetable with artichoke flavour, ornamental and hardy, ideal for winter dishes. A beautiful and useful plant for every garden.

A giant in the garden with silver leaves and edible stems. The white cardoon is tasty, decorative and steeped in Mediterranean tradition.

A generous and ornamental heirloom
