Do you want Orange Hat micro tomatoes? They fruit at about 6 to 12 inches tall. Cherry sized fruit.
I heard that Baker Creek Heirloom Seeds/rareseeds.com might be a bit problematic*. I have several little tomatoes maturing (still tiny) and instead of eating these, they will all go to seed saving. If you want a few, let me know and I will set them aside
*They were going to have a white supremacist speak at an event. Cancelled them due to outcry, gave no apology or acknowledgement.
