A note on seed longevity ... have some beans (Burpee “Gold Mine”, if it makes a difference) that I bought a lot of in 2019.
Just left them on the shelf (rather than the freezer), planted more last year, and more this year.
They’re still germinating.
I’m using 2019 bean seed this season, too. Good germination on all, with the exception of ‘Saychelles’ green pole bean, which needs to be re-seeded in 4 spots around my bean pole.
Larger seeds such as pumpkin, beans and such don’t last as long as smaller seed, but sometimes you get lucky. ;)
I had some Top Crop bush beans from 2015 that I tried. About half germinated. (Ferry Morse)
I now realize I got packets mixed up and planted Kentucky Wonder pole beans in the raised bed gardens (where I wanted bush beans) and bush beans where I wanted the other.
Oh, well ... we’ll figure something out.
