I've done all my seed orders. Found a place with several different sweet potato varieties, ordered 3 varieties. Minimum order is 5/variety, so 15 plants. I know where my extras will find good homes, since unless I get the extra plot I only have space for 12.
Orders included bush and pole beans, peas, tomatoes (lots of tomatoes), peppers, onions, and summer and winter squash, plus buckwheat and forage radish for soil improvement.
Most are open pollinated, so I can save seed, but a few are F1 for disease resistance.
I used to love Lunch Box tomatoes. I ordered some to see if they are still as good as I remember. They are F1s so no seed saving, alas. I could but no guarantees for the next generation. I ordered semi bush squash to take up less space. I ordered Shepherd peppers from Stokes to see how they compare to my "saved from the grocery store and 3 generations later" Shepherd peppers. That will be a fair trial, I will start them the same day the same way, grow the same, transplant to same conditions. Label well, record production, whole bit.
