We seem to be about mid-season for very early tomato varieties. The Indigo Rose I posted elsewhere earlier are possibly just past their peak. My Damsel tomatoes, plants bought live and shipped UPS from Ohio, are loaded with tomatoes. About one hundred medium to medium-small (right now) on an F1 hybrid that is indeterminate so they should keep going.
Meanwhile I've been buying tomato seeds, lots of seeds, exotic heirloom varieties and state of the art hybrids. I've actually had to create a Google Docs spreadsheet to keep track of all the varietals and their details.
Tomato gardening is nearly addictive.
