Tessaury is a heat-tolerant F1 hybrid cauliflower bred for speed and reliability, ready to harvest in just 58 days. This compact variety thrives in zones 3 through 10, making it accessible to gardeners across most of North America. Unlike many cauliflowers that sulk in warm weather, Tessaury handles heat better than traditional varieties, though it still performs best when grown as a spring or fall crop. Its modest size makes it well-suited to smaller gardens and containers, and its quick maturity means you can succession-plant for multiple harvests through the season.

Tessaury earns its reputation through sheer speed and heat tolerance. At 58 days from transplant to harvest, it's faster than most cauliflower varieties, and its compact growth habit means you're not wrestling with sprawling plants. The real advantage here is flexibility: while cauliflower is notoriously finicky about temperature swings, this hybrid was specifically bred to handle warmer conditions that would cause other varieties to bolt or fail. For gardeners in warmer zones or those with limited space, Tessaury removes two major obstacles.
Like all cauliflowers, Tessaury's edible head is the target. Roast it whole until golden and tender, steam it for a mild, slightly sweet vegetable, or chop it into florets for curries, stir-fries, and grain bowls. Its compact size also makes it manageable for single-pot dinners and smaller household cooking projects. Raw florets work beautifully in crudités or slaws, offering a crisp texture and subtle flavor.

Sow seeds in 72-cell plug flats and maintain soil temperature at 70°F (21°C) until germination occurs, then drop to 60°F (16°C) for healthy seedling development. Seedlings should be ready to transplant outdoors in 4 to 6 weeks. For a spring crop, time your seeding so transplants are no older than 4 to 5 weeks when they go into the ground; older plants become stressed and underperform. Harden off seedlings gradually by increasing their exposure to cold before transplanting.
Transplant 4- to 5-week-old seedlings outdoors when they are actively growing and have been hardened off. Space plants 18 inches apart with 24 to 36 inches between rows. Transplant into soil that has been amended with organic matter and has a pH between 6.5 and 7.5. For spring crops, transplant as soon as soil can be worked; for fall crops, time your transplanting so that heads mature before the first hard frost.
Harvest Tessaury heads at 58 days after transplanting when they reach full size but before they begin to separate or rice (develop a grainy, open texture). Cut the head from the plant at the base with a sharp knife, leaving a few wrapper leaves around the curd to protect it during storage and handling. Harvest in the early morning when heads are still firm and cool from overnight.
