Good germination rate!
Started germinating in about 48 hours, looking forward to a good harvest!

Great germination.
I'm successfully growing in the ground and in a pot. Doing well and am harvesting. Reminds me more of a chive because mine are very slender, but they may be way too closely planted. It's not easy spreading those tiny seeds! Even being slender, they have great flavor. Will grow again for fall. 😊

Buy it, buy it, buy it!!!!
I never write reviews but I just had to. I’ve ordered several different seed packets from different brands just to see which ones I’m going to stick with for my 2025 garden. I’m starting my seedlings indoors in trays and I got about 800 cells full of different ones. Let me tell you.. when I dumped this little packet out, by far, I was shocked of how much you get! It’s a great price, they look like healthy seeds and again.. you get A LOT!!! I’ll come back to let you know how germination went.. happy gardening yall!!

Good germination and healthy plants, but takes patience
I planted these Seed Needs Walla Walla long day onion seeds and overall I’m happy with the results. Germination was good, and the seedlings that came up look healthy and strong. The plants grew well once established, and the onions developed nicely. The only downside is that germination was a bit slower than I expected, and a few seeds didn’t sprout at all. It wasn’t a major problem, but it did require some patience and careful watering at the beginning. Once they got going, though, the plants performed well and produced good-quality onions with a mild, pleasant flavor. Overall, a solid product and I would buy these seeds again, just keeping in mind that they may take a little longer to get started.

Total waste!
I tried to start some of these seeds indoors in March. Not one seed germinated out of over 100 seeds sown. In April I planted the remaining seeds outside and not a single seed came up! A total waste of time and money.

Good germination and the transplants are doing good.
Bulk seeded these and got great germination. The transplants have thrived so far.

limited success growing the onions
We had limited success growing the onions. The germination rate seems low. We are gardeners for all kinds of veggies and flowers, so I doubt that it was something we did wrong with planting and care of the seeds.

Huge and sweet!
We had great success with these seeds. Almost all came up. Massive and super sweet onions. Very light paper on them though. So they don't store for very long. But that's just the type of onion.
