Potato onions: Throwing up seed heads

First, I want to thank the permie community for previous threads on this topic, especially Potato onions - the easy-to-grow "perennial' crop

Now I want to announce that I got seed heads on my very first try with potato onions. I'm told this is a rarity, so I thought I'd share with you all.

Seed heads:



I don't have an indoor space to start seeds that my cat won't dig up, but a friend is partnering with me to try this in her greenhouse. Wish us luck!

Lisa, could you post a follow-up?  How did the seeds do over the past 9 months?

I'm intrigued by the idea of getting potato onions to produce seeds and then new varieties, but I have not found any information on how to trigger potato onions into making seeds.

Cathy,

My friend w/ the greenhouse was going to grow the onion seeds as starts this year, but I haven't heard the results yet from her. The bulbs I planted in the fall are shooting up flower heads again this year.

Mine are growing here in very southern new mexico arid region, and all are flowering.  It's very interesting!  The ones I shared with others are reportedly blooming, as well.

It's been an exceptionally hot May.  We are also in the short day latitude, and that could also be the case. I haven't been growing them long enough this far south (previously was in north), so I don't know if this is normal for them in short day or hot areas.

Thanks for posting this, I'm very curious as to other's results.
