Status: August 14, 2018: TPS is now starting to trickle back into stock. Wild potato species come first and the mixes will be last, usually available sometime in December.
Having a hard time deciding where to start? I recommend starting with the tetraploid mix, which will give you a lot of variety and tubers that are pretty easy to store and grow again. Once you have some experience with that, either try the more specific tetraploid mixes or try the diploid mix, which is a little more challenging.
