Updated July 2026

Flame is an indeterminate salad tomato that lights up the garden with small, round fruit in a glowing orange, often flushed with a bicolor blush. The vining plant grows tall and produces steadily all season, giving you a generous supply of bright, cheerful tomatoes. The flavor is remarkably sweet and fruity with low acidity, making Flame one of the most refreshing snacking tomatoes you can grow. Its vivid color and easygoing nature make it a standout choice for home gardeners.

This is the quick guide to Flame tomatoes. For the full step-by-step on starting seeds, transplanting, feeding, and troubleshooting tomatoes, see our complete guide to growing tomatoes from seed.

Quick start

Start Flame seeds indoors about 6 to 8 weeks before your last frost, keeping the tray warm at around 70 to 80F for good germination. After frost has passed and the soil reaches at least 60F, transplant seedlings deep, burying about two-thirds of the stem to build a strong root system. Space plants 24 to 36 inches apart and stake or cage this indeterminate vine, which can climb 6 to 8 feet or more. Expect the first small, glowing orange, bicolor-blushed fruit in about 70 to 75 days, ripening steadily until frost.

Best tip

Pick Flame tomatoes once they reach their full orange color and feel slightly soft, which is when their sweet, fruity flavor peaks; harvest regularly to keep new fruit forming. In hot climates the vibrant fruit ripens quickly, so check daily, and in cooler or short-season areas start seeds early indoors and cage the vine to keep it productive.
