Hi Richard.
I wanted to post a photo of mine, but I haven't got one handy.
I grew seed from Kelly last year, and harvested small nests of perhaps 20 different lines. Some flowered in the first year, some didn't but all produced nests of bulbs. I have replanted each nest plant-to-row in my current growout. Some clones have every plant flowering, most have none, and a few have only one or two of that clone flowering. I'm leaving the flowers to cross again, to see what happens in the next generation.
To answer your question more directly, in the original generation from Kelly's seed I noticed little difference in size between the nests that flowered, and those that didn't. I didn't test for total yield, bulb size, taste or storage ability, saving such decisions for this year's growout, when I would have multiple clones of each line to compare.
In my opinion, flowering or biennialism aren't important traits for spud onions. If it reduces vigour, or bulb size, then I might eliminate it, but if the bulbs are tasty, store well, and of a decent size, flowering doesn't matter one way or the other. If you want to increase seed of Green Mountain lines, delve further into the combinations of traits within Green Mountain, or cross it back to some other allium, then flowering is important.

Ok ,so treat them more like the tree onions ya reckon ,only thing though could it cross with the Pukehohe Long Keeper red which are growing flower heads now.
My longer plan for the Potato onion was that some gardening friends a few k's down the road were going to start growing it from next year onwards because of the worry of potential crossing.

It's supposed to be Allium cepa, so there is a chance of crossing.

My potato onions grown from green mountain seed this year.  (ignore the weeds  )    Some have divided already. Not sure when to harvest them....it is fall here now and the days are getting shorter but the onions appear to be growing strong. Any suggestions? |

Did you get any seed heads starry

Did you get any seed heads starry No seeds heads this season. Maybe next year. Trouble I'm having is figuring out when to harvest them. They seem to be growing strong even though autumn is well upon us and temperatures are dropping and days are shortening. I tried stomping them but they just grew back. |

I'm officially on the TPOS bandwagon. My yields rival bulb onion (which might just mean I suck at grow bulb onion btw) but anyhow, I'm impressed and am moving toward growing potato onion and walking onion base bulbs as a winter and summer onions respectively.  |

I do get some seed though not much from these common yellows.

Nearly all my F2 Green Mountains are flowering this summer - I should get buckets of seed. I also suck at growing bulb onions, and would love to get anything that big. Well done.

I was pretty surprised by their size but I've noticed, they are often pretty good hence my changing allegiance.

.... Quite a few regular onions will divide and become perennials if allowed to. Now they are usually culled. In fact I'm trying just that ... create a potato onion from regular onions. For me the tricky part is to fix how much they divide to make asexual propagation interesting, without overdoing it an ending with onions that are too small.
[Emphasis above is mine]
Thank you. This is most likely the origin of potato onions a few centuries ago.

Telsing, are those bulbs from straight up Green Mountain seed? (sorry if you've posted it and I missed it...)

Those? No, they are common yellow hence I'm interested in trying Green Mountain too.

Hm, I -just- ordered some Green Mountain and Dakota Mountain, as well as some seeds from Kelly. I don't know why I didn't think to look here about potato onions...
