I planted some Green Mountain seed in SH autumn 2013, and held some back to plant in SH spring 2013. Both batches did well, but the autumn planted ones were larger and more productive. This is the autumn planted set. The spring planted ones are smaller, and a little bit later to mature - but it might just be the bed they are in.

It seems that you have some behaviors like green mountain (the bulb divides) and some gives a unique big bulb that will divide in numerous small bulbs, that will give each a big bulb again, like gold mountain.
Anyone got true seed of potato onion? Specifically one that is shade tolerant. I usually will only do trades.
Kevin, do you know of a shade tolerant one? or hoping? Kelly Winterton sells seeds out of Utah (google him or Green mountain Potato onion). I'm about to harvest some, progeny of his, but my seed is promised. T

I just asked since I plan on planting them in a raised bed in the back which is trellised over by a passion fruit vine. Onions did do pretty well there but the vine wasn't that big. But from what I read, there should be enough genetic diversity for it to adapt.
Zone 10a, Garden year round but too hot in the summer for many things. Focusing on breeding my own landraces for drought tolerance and heat tolerance.

I split a sample I got from Kelly between two pots because I wasn't sure. Stratified one and left the other alone. The stratified one germinated very poorly (10% germination), whereas the other did much better for emergence (speed and number; 50%+ germination).
Wow. All of my overwintered yellow potato onions are putting up flower stalks. Normally I wouldn't expect to see that for a few months yet. Interestingly, none of the overwintered KW potato onions are doing this.
Growing where temperate rainforest meets the sea (WA coast): Jan avg low temp ~34*F, Aug avg high temp ~69*F, ~111 annual inches of rain, but only about 15 inches May-Sep, salt air, lots of wind.
