If you live in an area where the last frost is in late April you should be looking for short season tomatoes. The will ripen under 70 days from planting as a plant in your garden. Longer season varieties will take too long to ripen and will go to a green mush if your cool weather arrives too early for the tomatoes to ripen on the vine.
Typically it is the smaller the tomato fruit the shorter it takes for the tomato to develop and ripen. Cherry and Roma tomatoes are among the short season group. Some tomato breeders are now developing even shorter season varieties.
