I recieved the multiplier onions I purchased.

 This is from the order I bought from.. I paid $13.00 including shipping.

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.

Copper Shallot

Copper Shallot..pink tint to the flesh   Info from person I bought this from.
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

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.

Multiplier Onion's and shallots order recieved.

 I received an order I purchased  for real multiplier onions.

 The red white and yellow sets I received on another post may be just onion sets. I paid allot of money for. But will not know till next summer if I was cheated. 

What I have now you can tell by looking at them. They are real!

Green Mountain Multiplier:   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.

Copper Shallot:  This is an old school shallot that has a very low tendency to flower.  Newer shallots are almost all grown from seed and will blot if planted.  This one is a beautiful coppery color and makes firm little bulbs and store very well.

I'itoi:Multiplier Onion  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.

Latin Name: Allium cepa var. aggregatum. Synonym: Allium cepa Aggregatum Group.  

Details from the seller. 

2 bulbs each of the classic heirloom






Yellow Potato Onion:  small to medium multiplier.  Extremely good keeper once cured out.

Yellow Potato Onion,  The newer Green Mountain Multiplier potato onion, Copper Shallot and I'itoi  All of these reproduce from bulbs, so you plant one and harvest many.  Small bulbs of Yellow potato onion, copper shallot and green mountain produce large bulbs if small bulbs are planted, or they produce many smaller bulbs if a large bulb is planted.  The collection contains two of each bulb.  In many areas, these can be fall planted and should be.  The yellow potato onion is very hardy, and I believe the Green Mountain is too, but I can't be positive about that.  Copper shallot can easily survive temps down to 20 where I live, beyond that I'm not sure.  I'itoi may be more cold sensitive, but should survive temps above 20 degrees if fall or winter planted.  Fall is a traditional time to plant potato onions in the south.  Since these reproduce by bulbs, there is no need to ever buy seed again.  Consider this an investment and a great way to test several varieties without spending a lot.  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.

Growing potato onions

This year I ordered red, white and yellow potato onions from Canada. The look like small onion sets. I will plant them in different areas of the yard. They are perennial onions the divide, One onion will tun into many onions. Like planting potato tubers one grows more. Except these are not planted deep like potatoes. They are planted near the surface and mulched over a bit to go thew winter.
This video I will show you what received. It includes  The Egyptian walking onion and some hard neck garlic to.

I also ordered (TOPS) True onion potato seeds  I will start them indoors this Jan or Feb. Then plant outside in Spring. They will become the seed stock for the following year.

What I ordered is an open pollinated mix of Coral mountain, White Mountain and Green Mountain potato onions. These varieties are known to produce on average tennis ball size onions.
