Lycopersicon lycopersicum: The first ripe, juicy tomato of summer is a delicious milestone of the season for gardeners. Each year we test and evaluate more than 250 tomato varieties to bring you the most flavorful, best performing selections, for every desired use. An array of nutrients and antioxidants including the especially potent lycopene, found in its highest concentration in tomatoes, supports healthy eyesight, cardiovascular health, cancer-fighting capacity, and more.
Our heirloom selections carry the heritage of the many generations who carefully collected seed from their favorite tomatoes to preserve these historic, colorful delights. As they selected the most flavorful fruit, and as gardeners have maintained these classics for generations, they have also preserved the high nutritional value, which is lacking in modern supermarket cultivars. We have trialed hundreds of these old varieties over the years and selected our offerings after evaluation of their performance at our London Springs research farm and, of course, for the quality of their fruit. From early performers to long-season treats, our heirlooms are full of character, with incomparable flavors and textures. By saving seed from your best plants, you can keep tradition alive by making it your own heirloom, perfectly naturalized to your garden after several seasons.

CULTURE: Sow seeds indoors into sterile seedling mix 6-8 weeks before your last spring frost. Plant, water lightly, and cover with plastic or a Propagation Dome to keep the seeds from drying out. When the first set of true leaves has emerged, up-pot into 3-4 inch pots and place in an area with full light and cooler temperatures (60-70°F). This will help prevent legginess. Water carefully, allowing the soil to dry on the surface between watering, but don't let the plants wilt. Fertilize with fish emulsion every 10-14 days. Seven to ten days before you want to transplant outside, set the plants in a sheltered area outdoors to harden off. Bring in or cover at night to protect from frost. After the danger of frost has passed, transplant into well worked garden soil. Blend 1/4 cup of our complete fertilizer into the soil around each plant. If you have acid soils or have been bothered by blossom end rot, a handful of bone meal should also be added. Space determinate varieties 18-24 inches apart and indeterminate varieties 20-30 inches apart. Allow 3-4 feet between rows. If your plants have become leggy, plant them deeper; the stems will actually sprout roots. Water very lightly at first, allowing the stems to adapt. To promote early growth and better yields use season extending products such as Wallo' Waters, Kozy Coats, Victorian Bell Cloches, or Red Plastic Mulch.
DETERMINATE/INDETERMINATE: Determinate varieties spread laterally and therefore do not require staking. Determinate varieties ripen at once so are a good choice for gardeners who love to can. Indeterminate varieties grow vertically until the bitter end and need to be staked or trellised for best production. They produce fruit until frost, leaving you some green tomatoes at the end of the season.
INSECTS/PESTS: Use Pyrethrin or crop row covers to discourage flea beetles early in the season, when they can be most destructive. Tomato hornworms can be controlled with Bacillus thuringienses (a bacteria also known as B.t.) sold as Monterey B.t. (ZIN503).
DISEASES: Natural genetic plant resistance is the best form of disease control. For diseases like early and late blight, a strict 3 year rotation and a sanitation program that includes destroying all the vines at the end of the year are your best defenses. Contact your local county extension agent for more information.
SEED SPECS: Minimum germination standard: 80%. Usual seed life: 3 years. Days to maturity are calculated from date of transplanting; add 30-35 days if direct seeding.

Started several of these from seed. They grow vigorously with substantial root development until they set fruit and then slow down. Growing them in containers and raised beds. Some of the earliest fruit set and ripening of any of my heirloom varieties. Not overly productive plants. The fruit is large, firm, sweet, and meaty. A great slicing tomato. One of the best heirlooms as far as taste and quality for my PNW location.

Plant started out fine and grew to about 4.5 feet. Set few tomatoes and then turned a pale yellow and died about mid-July. It was in the same raised bed as 5 other tomato plants which were, and still are, healthy and productive.
not worth the space

purchased as a plant. very healthy at first. Nearly every tomato cracked and had to be thrown away before they even turned color. Got 2 all season (SE PA). also got septoria leaf spot badly...picked off the diseased leaves and in mid august only has leaves at the top of the plant. not worth the space sadly.
