onion, leek, scallion


Family: Alliaceae (Onion Family)

Genus: Allium

Hardy/Half hardy biennial. Allium seed should be sown early indoors and transplanted into the garden in spring. They are slow growers initially and do not compete well with weeds. Most alliums are tolerant of a light frost. Leek and some scallions can over-winter (with protection in severe winter climates) to provide seeds the following year. Some scallions are perennial/dividing kinds and can produce multiple seed crops. While some bulbing onions can survive mild winters mulched, most should be over-wintered in a frost-free location to be replanted in the next spring. Leeks can be root-cellared. Flowers are insect pollinated. 

Leek (Allium ampeloprasum)

BLEND-Leek Blend 

We searched for leeks and found many distinct cultivars. Some of these are rapid growers and just great for summer greens; others are winter hardy and are nice winter storage varieties. There are more than a dozen varieties here. As a generalization, tall slender summer kinds tend to be bright green, thick winter kinds are often blue-green. Long white shanks blanched when hilled or mulched as they grow in the field. You will find some nice variation here including rare “bulbing” kinds and crosses from our grow-out in 2008. Pkt.

HEIRLOOM CV-Saint Victor

This is a traditional French leek which is very hardy and produces a nice thick base. The winter "greens" takes on a purple tinge in cold weather.  We grew this seed crop in isolation and continue to select for purple foliage. One of the best and most beautiful overwintering leeks.  Similar to Bleu de Solaise.  Pkt. (100 seeds)

BLEND-Onion Blend

This is a mixture of bulbing onions, sweet and storage kinds, white, yellow and red colors. Small and large bulbs. These are mostly day neutral or long day kinds suited for northern latitudes (north of 38° latitude in the U.S.). More than a dozen cultivars from US, Australia, Japan, Great Britain and Italy. Check out the diversity to discover your best performer and then overwinter the bulbs to produce your own seeds.  Some of these will produce nice scallions and pearl onions or large bulbs depending on season.

BLEND-Scallion Mix

Mixture of green onions or scallions; some with a red blush at the lower part of the stem. Summer kinds as well as perennials that may prove very winter hardy. Some may reseed for you, some will keep dividing. From our production and many other sources. Depending on latitude and season, the A. cepa kinds in this blend may produce bulbs. Pkt. (100 seeds)

SELECTION-Welsh Onion: “Mild and Crisp”

A selection from LI Seed Project which in our taste tests were considered more pleasing than other selections of a mass cross Pkt. (100 seeds)

Our objective with alliums has been to grow dozens of varieties of leek, onion and scallions and then select for those that are useful as well as sustainable (easy to produce a seed crop or become perennial in the garden) for us.  Plant vigor is important for us as well as performance in organically managed sandy soil.

Some of the allium projects in the future include making selections of heirloom onions developed in New York and Connecticut and well adapted to our climate but dropped by commercial seed sources.  These were “hard” onions which stored well over the winter.
