As the title suggests, I am on a mission to find seeds for these peppers. I am in southeast Michigan and have oodles of varieties of all sorts of crops for trade.
If you have a Rural King nearby you might look there. They carry Livingston seeds. I don't remember seeing that variety of pepper but I wasn't really looking at the peppers so it may be a crapshoot.
I want to think they are called "big red" now. I grow them every year, from saved seeds, most definitely open pollinated, they grow true year after year. Blocky thick fleshed and sweet as can be. I eat them right off the plant. They are awesome, sliced or diced bagged and frozen. and... stuffed red peppers 😋 so versatile to cook with.
Agreed. RK sells Livingston seeds. You could contact them and send them your photo above and see if @HoleySmokes is right. Good luck!
I know that I Just started my sweet pepper seeds this weekend and they take F O R E V ER to sprout.
