Great germination
I got 90% germination on these seeds. I have Patterson onions in storage in mid-February that I grew last Summer, so yes, Patterson's are long-keepers.

Loves these Onions!
Patterson onions have become my go-to for long day onions here in MA. They grow great, and store for months, even when storage temps are maybe a bit warmer than they ought to be.

Finally Found!
Finally found what had been "Copra" in looking through Seeds n Such! We were sad we couldn't find this long keeper for a long time. Just found one last one down in the pumphouse and it's still good and firm from last fall! "Patterson" is a great, long lasting onion!
