Sub Arctic Plenty breaks every rule about tomato growing, delivering ripe red fruits in just 50 days from transplant even in the harsh conditions of the Canadian Yukon. This remarkable determinate variety was specifically developed in Canada for the shortest growing seasons, producing 2-ounce round red tomatoes on compact 18-36 inch plants that thrive in zones 2-9. With its incredible cold tolerance and container-friendly size, this tomato proves that even gardeners in the most challenging climates can enjoy homegrown tomatoes.

Born from Canadian breeding programs, Sub Arctic Plenty stands as one of the earliest fruiting tomatoes ever developed, maturing faster than any other heirloom variety. The compact determinate plants require no staking or caging yet produce high yields of all-purpose 2-ounce fruits perfect for fresh eating. Its exceptional cold tolerance allows successful cultivation in regions where other tomatoes fail, including areas bordering Alaska, while still performing beautifully in warmer climates where its short season helps avoid pest and disease pressure.
These medium-sized round tomatoes excel as versatile all-purpose fruits, perfect for fresh eating in salads, sandwiches, and everyday cooking. Their 2-ounce size makes them ideal for slicing while their determinate habit provides concentrated harvests perfect for preserving and canning projects.
No timeline data available yet for this variety.
Start seeds indoors 6-8 weeks before the last expected frost, sowing 1/4 inch deep in quality seed starting mix. Maintain soil temperature around 70-75°F for optimal germination and strong growth, providing bright light or grow lights once seedlings emerge.
Harden off seedlings over 1-2 weeks by gradually increasing outdoor exposure, then transplant after all frost danger has passed. Bury seedlings up to their first true leaves to encourage stronger root development, as tomatoes can develop roots along buried stems.
Harvest tomatoes when they reach full 2-ounce size and develop deep, even red color throughout, typically 50-59 days after transplanting. Ripe fruits will yield slightly to gentle pressure. Twist and pull ripe tomatoes from the vine, or use garden shears to cut the stem if fruits resist easy removal.
As a determinate variety, Sub Arctic Plenty requires minimal pruning beyond removing any suckers that develop below the first flower cluster and maintaining good air circulation by removing lower leaves that touch the ground.

“Sub Arctic Plenty emerged from Canadian agricultural research focused on extending tomato cultivation into the country's harshest growing regions. Bred specifically for extremely short growing seasons, this variety represents a breakthrough in cold-climate agriculture, enabling successful tomato production in areas as challenging as the southern Yukon territory. The development of this cultivar opened new possibilities for northern gardeners who had previously been unable to grow tomatoes reliably.”
