White Tomesol is a rare heirloom tomato that delivers both visual intrigue and remarkable flavor. Its cream-colored fruits weigh around 170 grams (about 6 ounces) each and arrive at full ripeness in just 80 days, making it one of the fastest heirlooms to produce a harvest. The vines grow indeterminate, meaning they'll keep producing all season long, and they're known for setting heavy yields of these smooth, beautiful fruits. What truly sets White Tomesol apart is its combination of sweetness and richness, with a fragrance that announces itself in the garden. This is a tomato that serious growers seek out.

Few heirloom tomatoes balance speed with flavor the way White Tomesol does. Its cream-colored fruits are visually distinctive, smooth-skinned, and consistently sweet with a depth that makes them exceptional fresh. The vines are productive powerhouses, setting heavy crops throughout the season on an indeterminate plant that thrives in full sun. At 80 days to maturity, it beats many other heirlooms to the table without sacrificing the complex flavor that makes heirlooms worth growing in the first place.
White Tomesol is grown primarily for fresh eating, where its sweet, rich flavor and creamy color shine on the plate. The smooth skin and medium size make it excellent for slicing into salads, serving alongside cheese and herbs, or simply enjoying fresh off the vine. Its flavor profile also suits fresh sauces and gazpacho, though many gardeners grow it specifically to showcase its distinctive appearance and taste as a conversation piece at the table.

Start seeds indoors 6 to 8 weeks before your last spring frost. Seeds germinate best at 68 to 82 degrees Fahrenheit and typically sprout in 7 to 14 days. Sow at a depth of 1/8 inch and keep soil consistently moist but not waterlogged. Once seedlings develop true leaves, thin to one plant per cell or pot.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Transplant outdoors only after all danger of frost has passed and nighttime temperatures reliably stay above 50 degrees Fahrenheit. Space plants 24 inches apart in full-sun locations with well-draining soil.
Harvest White Tomesol fruits when they reach their full cream color and yield slightly to gentle pressure at the blossom end. The skin should be smooth and glossy, not dull. Pick fruits at this peak stage for the best flavor and fragrance. On an indeterminate plant, you'll be harvesting continuously throughout the season once fruiting begins around day 80. Morning harvests are ideal, as fruits picked in cool temperatures store better and taste fresher.
As an indeterminate variety, White Tomesol benefits from selective pruning to improve air circulation and fruit quality. Remove lower leaves once the plant is established to reduce soil-borne disease spread and allow air to flow near the base. Pinch or prune suckers (shoots that grow in the fork between the main stem and branches) throughout the season, but avoid excessive pruning that removes too much foliage and sunlight exposure. Stop pruning about 4 weeks before your first expected frost to allow remaining green fruits time to mature.
