Leek, Verdonnet (Organic)

Allium ampeloprasum.

Our best leek if you want beautiful, tall, white stalks from the fall through winter. Of the Swiss giant type, Verdonnet is a landrace variety that has been improved by an unknown Swiss farmer/breeder. Swiss giants are typically great summer leeks, but these large, bright-green, tasty leeks stand all winter and into the spring. A very tall shanked leek good for hilling or trenching to blanch the stalk. Given to us by the Irish Seed Savers Association.

Geographical Origin

Sow indoors in flats with good potting soil February through April. Transplant into the garden April through June, once plants are at least the size of a No. 2 pencil lead. Space 6” in rows that are 1’ apart. Leeks benefit from frequent watering and shallow cultivation. Harvest as needed throughout autumn and winter.

Seed Saving

To save seed, leave 20 or more plants in the ground through the second spring and summer. Large, beautiful, globe shaped flowers attract pollinators. Isolate from other leeks by at least ½ mile.

    Where did you grow this variety? Washington

    As with Pancho, which I also grew in 2021-22, this is a hardy, beautiful, tasty leek that, while I don’t think it really produced mature leeks by the fall as stated in the description (mid-March sown, mid-late April transplanted), has delivered wonderful leeks in the late winter and now into spring. We are working are way through them and to date my favorite use has been for cardoon (Argenté de Genéve Inerme, also from Adaptive) and leek pizza. If I had to choose between Pancho and Verdonnet, I slightly lean toward Verdonnet.
