Description

The Thessaloniki Tomato is a Greek heirloom. A tomato so epic that Homer could have written an ode to its plump round fruits that ripen from golden yellow to vivid red, high yields in high temps, and a rich, earthy flavor that’s well-balanced between sweet and acidic. This one’s a keeper, both in the garden and on the countertop. By the time you eat a few of these, you may even be able to pronounce it.

These Indeterminate Thessaloniki Tomato Seeds produce Greek heirloom tomatoes known for their high yields, rich flavor, and adaptability to warm climates. This variety is characterized by its vigorous, indeterminate growth habit, requiring trellis support and regular pruning to manage its vigorous vine. The tomatoes are medium-sized, ripening from golden yellow to bright red, and are valued for their well-balanced flavor, combining sweetness and acidity.

Recognized for heat tolerance, these seeds are suitable for planting in full sun environments during spring and summer, with a germination period of 7-14 days at soil temperatures between 75°F-95°F. The plants require soil with a pH level of 6.0-6.5 and should be spaced approximately 24 inches apart within rows spaced 36-48 inches apart for optimal growth. 

Indeterminate Thessaloniki Tomato Seeds are ideal for gardeners seeking a heat-tolerant, high-yielding tomato variety that matures in about 75-80 days, suitable for fresh eating, canning, and storage. This heirloom Greek variety is well-suited for home gardens and small-scale commercial growers aiming to produce versatile, flavorful tomatoes.

    Customer Feedback:

    Planted two seeds, one came up and is moving along well. Germinated in the expected time and has already sprouted it's first set of true leaves. Wish both would have sprouted but if I don't see any action on the second one by next week I'll plant another. Sometimes one seed is a little behind the other, so we'll see. I'm planting at least 50 varieties of tomatoes to taste so as long as I get something out of each plant, I'm happy. It's when all the seeds are duds that I get upset.

Safe Seed Pledge

 

OUR PLEDGE TO YOU

Agriculture and seeds provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations.

For the benefit of all farmers, gardeners and consumers who want an alternative. We pledge to you that we do not knowingly buy or sell genetically engineered seeds or plants.  The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats.

We wish to support agricultural progress that leads to healthier soils, genetically diverse agricultural ecosystems and ultimately healthy people and communities.

We do not buy - OR - grow any seed from large corporations that make Genetically Engineered seeds.  We don't touch that stuff and we never will.

The seeds we offer aren't like varieties you'd typically find at a garden center. 

Every variety we offer is 100% OP (open-pollinated).  Open-pollination means that you can safely save the seed after harvest and preserve a collection of heirloom seed for many generations to come.

To make it perfectly clear ... Our seeds do not contain any exogenously inserted embryogenesis deactivator genes caused by human intervention.
