Egyptian Onion or Walking Onion

For many years this was my favorite all purpose onion.  Always just outside my kitchen door, the patch of walking onions (Allium cepa var. proliferum) was there in summer and in winter to quickly grab a handful of greens that I could toss into omelets, burgers or salads.  Even the little topsets I could use like garlic cloves in my cooking.  There are a few different varieties, all old time selections.  In my parents garden they were real tall (or maybe it's because I was so short), the strain I have from the old Pilgrim State Hospital Farm which was in Brentwood and is a strain also from the 1950's was shorter but more aggressive spreaders.  I have seen some kinds that even produce a few usually sterile flowers in among the topset bulbs.  The in-ground bulb divides to produce clumps on onion greens.  In late spring they send up their "seed" 2 foot high stalks which bear a cluster of small bulbils which will send out shoots as well.  The top-heavy mass topples to the ground where the top set "bulbils" root and help to form an ever expanding patch.

Some folks find the onions a bit hot for their taste but not me and like any onion, once used in cooking they become more mild and sweet.



Leeks are versatile in use and easier for us to store and raise seed crops than bulb onions.  They are very pleasant used in salads, minced for their mild flavoring or on the barbeque during the summer when they are still small.  A row of leeks nicely tended and hilled to blanche those beautiful thick stems really pays off big in the fall and winter when those frosty days call for a bowl of hearty potato leek soup. Leeks find their way into many of the winter dishes I prepare. Often I'll use them like a mild onion as a flavoring or when I am doing a stir-fry or tossing a massive stem into the roasting pan to make a great gravy or in winter stews.  One doesn't use the large leafy part on the leek because it is tough.

For a seed crop we have a mass cross of the hardiest of a dozen or so varieties that winter over here in the field. The summer leeks are too tender to survive the lowest temperatures, which can dip down to 10 degrees F. in early to mid January or even below 0.  We expect to maintain as much diversity in this mix as we can to get leeks that serve a number of culinary purposes for us.

Leek seed is sown in late winter or early spring indoors in seed flats and later transplanted to the garden.  They respond well to good garden soil rich in organic material.  To produce long white shanks you can begin to hill the plants early on.  The hilling will also protect the leek during the winter.

We also save the seed and continue to improve Saint Victor, an ancient European Leek which performs well for us and always yields quality leeks for the table, beautiful lavender flowers and a bountiful seed crop without any fuss.  Saint Victor is an odd kind of leek in that the normally gray-green foliage develops a pronounced purple cast after frost which is maintained during the winter.
We noticed that St. Victor can produce in the second season a cluster of very large and pleasant tasting garlic-like cloves at the base of the stalk as the shank of the leek breaks down and just before the flower stalk is produced. We discovered the bulbs when we pulled about 70% of our overwintered St. Victor crop out (selecting for the best purple foliage) in April. The cloves are a lot like the huge elephant garlic that you see in produce markets which is, interesting enough, in the leek family, not a garlic. I wonder if this is the "bulbing" characteristic that has been selected against by modern leek breeders? Heirloom leeks are looking better and better to me. Another very old kind that I obtained from friends in Europe produced a head with only a few flowers but hundreds of tiny bulbil topsets. Very neat. Chance discoveries like this will often send me into a new direction of selection and my breeding objectives change. I never imagined that I would have so much fun with leeks of all vegetables.


Bulb Onion

I really ought to specialize in a particular crop, maybe that would allow more time to produce significant breeding accomplishments, but the truth is; that in growing each diverse batch of vegetable seed, especially the less modern varieties, there is so much to discover and it is just so fascinating. We haven't done much with saving seed to produce bulb onion (Allium cepa).  I would like to, perhaps in the future we will.   At latitudes of 40° and higher we grow long day onions or day neutral types.  Long Island is at 40° N which is about the same as much of Spain and Italy.  We have successfully grown onion seed; in fact, from Spain, Italy, Japan, England and Austrailia.  There are also really fine kinds that were developed in the 19th century in Connecticut and Massachusetts and New York Early is a variety from the mid 1900's which is a good keeping variety still worth growing We managed to produce a small seed crop.  Our local onions tend to be selected for fertile river valley soils or muck soils and don't always perform well on the sandy soils in our gardens.  Grow onions fast on rich soils with ample moisture.  We sow seed early (late winter) to obtain nice sized transplants which go into the garden in spring.  That allows the onion to produce early green onions in late spring and then begin to bulb up in the early summer during the long days for the fall harvest.  Young onion seedlings and transplants require care.  They do not compete well with weeds.  The best storage kinds are the "hard " onions which are good all-purpose cooking kinds.  The large sweet kinds such as the Spanish Onion and the many developed from this line tend to be poorer keepers.  Most bulb onions tend to winter over poorly in the fields for us although the Italian "Torpedo Onion or Bottle Onion" from Florence in both red and brown skin forms seems rather hardy and have produced seed here.

Hard onions properly cured and dry after harvest will usually last the winter in a cool but above freezing location.  In the spring they can be planted outdoors for a seed crop which ripens in July usually.


Scallions or Green Bunching Onions

 Scallions are used for the tender greens.  In some cases they are produced from young bulb onions (Allium cepa) and there are some kinds of bulb onions that can be used for both the green scallions and later on, the developing bulbs.  The mild White Spanish Onion is a nice dual use onion. In fact, there are a few beautiful related white onions that produce nice green scallions that can be marketed with their white bulbs. I would like to look closely at these summer onions someday.

One of the easiest sustainable bunching onions is the true scallion or Welsh Onion (Allium fistulosum) which is actually Russian, I am told.  Some of the nicest Welsh Onions have been developed in Japan and are essentially perennial.  They are winter hardy (maybe because of Siberian ancestry) and the roots although never bulbing, produce new green onions by division.  The Welsh Onion can also produce copious seed.  We grew several strains and found variation in flavor and texture.  We are now growing a very mild crisp selection which seems to just get better each year. Home produced onion seed. What can I say? You can't get fresher seed.
