Best seeds and best gardening youtube channel, especially if you live in Mid West.
These germinated great and were all off to a good start, but they ended up getting potted up into too heavy of dirt and became stressed and got killed off by spider mites shortly after. Will be trying to grow again but will be taking better care of them while young.
Asclepias (Milkweeds) are very important to me, and especially this species! I often get my milkweed seeds from different companies, for a few reasons, but I noticed that my Swamp Milkweed seeds from a different well-known company were significantly smaller, and overall pretty scraggly-looking, compare those to these?- complete 180! These are massive, healthy looking seeds!
These germinated in no time and are thriving very well
Grew these for the past three years and I will keep growing them for many more. I highly recommend them. Great germination rate. Every onion grew to the size of baseballs and others a bit bigger and they store very well.Best long day onion I have ever grow.
I am very happy with my heirloom seeds. I cannot wait to germinate them.
Started my seeds on 12/31/25. I’ve had almost 100% germination and the onion seedlings are a couple of inches tall at this point (1/9/26). Looking forward to a great harvest!
Grew these last year, so I bought more seeds! they were awesome, very prolific and tasted great!!
I started them early....did waterjug winter seed starts .. they did very well....grew up to be nice sturdy plants, bearing lots of fruit! Thank You!!
