Swiss Giant - Zermatt

The earliest in our series of open pollinated varieties. This is in great demand for the baby leek market. Long shank, with erect leaves and a good base.


Tozer Seeds bred. Medium green leaves with long shanks. Ideal for late autumn production before the serious frosts set in.

Conway F1

First/second early hybrid variety. Can be sown in modules in January, giving an early, heavy crop when prices are often at a premium.

Tornado (Autumn Mammoth)

Tozer bred open pollinated variety maturing after Zermatt. Excellent for full size production, can also be used as a baby leek.

Oarsman F1

Mid-season maturity cropping from mid October. Terrific vigour and uniformity with a medium shank and dark erect leaves.

Neptune (Blue Green Autumn)

Hardy, dark blue-green plants with a good shaft length. Has some rust resistance and peels well for a quick pack out.


Toledo has dark blue-green erect leaves with an excellent long shank for this time of year. Will follow on from Neptune giving good quality leeks into March.

TZ 0233 F1

Second early variety that bulks quickly. Good dark blue-green foliage which contrasts well with the lengthy white shank. Trials have shown this variety to be a consistent performer with good uniformity, bulbing resistance and field resistance to rust.

Cambridge F1

Maincrop variety that also performs well in earlier and later plantings. Our heaviest yielder in trials. Dark blue-green erect foliage showing good field resistance to rust. Bulky, well filled shanks which are easy to strip and peel. A strong root structure suggests this variety will perform well in organic situations.
