You sure did get a good second crop. I love the variety of plants you planted and the colors of the different spuds. We also grow potatoes, but our zone has a shorter growing season so it's impossible to plant twice.
I like the idea of growing in containers which I've never done. We grow directly into a raised bed and this year was the best one we've ever had, growing 110 pounds.
When growing tubers

you never know what you've got until you unearth them and that day is very exciting.
