About Flame Seedless
Flame Seedless delivers crunchy, sweet red grapes that kids devour — seedless, early-ripening, and beautiful in clusters. It's the red table grape of choice for warm-climate home gardens.
Flame Seedless requires 100 chill hours — the number of hours between 32°F and 45°F during winter dormancy. Without enough chill, the tree may fail to flower properly or produce poor fruit.
Common Challenges
Prone to bunch rot in humid conditions; needs careful canopy management for air circulation; requires hot summers.
Common Misconception
Will Flame Seedless produce more fruit in colder climates?
Not necessarily. Flame Seedless only needs 100 chill hours. Planting in very cold zones (6 or colder) risks winter damage without improving fruit production. The ideal zones are 7-10 where the tree gets enough chill without excessive cold stress.
