You won't have any issues with Territorial - they have some fun varieties and their packets are generously portioned.
If you are looking for more varieties than you will EVER know what to do with, I very strongly
recommend Tatiana's TomatoBase
. She is out of Canada, so shipping can take a few weeks to the U.S., especially right now, but her selection is completely out of this world and she is a lovely individual to do business with. I doubt most people have even heard of 98% of the varieties she offers. I have spent weeks perusing her site to narrow down what I wanted.. but, of course, I want them all. Fantastic.
