|Green Mountain Multiplier onion|
Green Mountain Multiplier onion : (Allium cepa) Large variety recently selected by Kelly Winterton. I find that it doesn't cure out as reliably as the yellow potato onion it was bred from, and it has more tendency to bolt. Once cured though, it keeps very well, into spring, and it is most definitely larger, at least twice as large on average.
This is the old school type of shallot that does not tend to go to seed, but reproduces like a potato onion from planted bulbs. For each bulb planted, a cluster of new bulbs forms. Usually the reproduction rate is somewhere around 6 to every one planted. These form hard bulbs that store like a rock once cured. Some losses are always incurred during curing and storage, but most will easily keep until spring in fine eating and planting condition. It is still better to plant this fall if you can, because they may not all make it till spring. I have no idea how hardy this variety is in very cold climates. The person I got this from said" Here I can grow it all winter through temps down to 20 degrees and it won't bolt if fall planted. The bulbs are nice, with fewer divisions under the skin than the yellow potato onions I grow. This is a great variety of french shallot that you can grow indefinitely without ever having to buy seed! The modern varieties are bred to grow from seed and will bolt if a bulb is planted"
I'itoi onions This is a very rare multiplying onion that make little bulbs that are a lot like a tiny shallot. It is very small, but very productive. It was supposedly introduced by the Spanish centuries ago and has been grown by the O'odam people of the southwest ever since. It can also be grown and harvested as a scallion or as chives if left to grow without dividing. A single bulb can turn into over 100 at the end of the season
Re-growth begins again in July and prosper for about 10-11 months annually. As a hardy onion, they require about a third less water than most, since they
seldom get water more than twice a month in Arizona type weather
Plant 12 inches apart about 2 inches deep.
When they are young (green onions) they should be dug up with a spade or garden fork and not pulled like regular onions. Fibrous roots go down about six inches, which is why many end up pulling off the tops and leaving the bulbs in the earth.
|Yellow potato onion|
The Yellow potato onion small to medium multiplier. Extremely good keeper once cured out. It is a hardy heirloom multiplying onion once popular in home gardens, but now uncommon. When one bulb is planted in fall, winter or spring, a cluster of onions is produced. The ratio of reproduction is around 6 produced for every one planted. The number of bulbs in a half pound will vary, but it’s usually 10 or more. Generally, if a small bulb is planted, a few large onions will be produced. If a large bulb is planted, more, but smaller, onions will be produced. The bulbs are planted between fall and spring. If fall or winter planting in cold areas, the onions may need to be hilled up with dirt for the winter and the dirt pulled away from the bulbs in the spring. Yellow potato onions are similar to traditional shallots. The flavor is generally somewhat mild and sweet. They grow to about 2 to 2.5 inches in diameter if well cared for. The flesh is yellow. They can keep extremely well, into and past the following spring. They mature in late summer from either fall or spring planting, with earlier plantings ripening slightly earlier. The average multiplication is around 6 bulbs per one planted. So, if 10 bulbs are planted, survive and reproduce and all the offspring are planted, the math works out to, 60 in year one, 360 in year two, 2,160 in year three and 12,960 in year four. So, consider these bulbs an investment that you can start to share with other gardeners in a couple of years. Be warned that someone on ebay has been selling small commercial onion starts as potato onions for years. Potato onions do not produce perfect, round, clean, small uniform bulbs. These are the traditional yellow potato onion.
The potato onions and shallots usually produce about 6 bulbs for each one planted. The math works out to 6 = 36= 216= 1296 in year three! and the I'itoi can produce large clusters of small onions in one season.
