Blue Fire Vine Tomato

Description

We have explored glamorous pinks, rugged reds, tangy greens, moody purples, and sweet oranges. Now it’s time for some real drama. Blue Fire (sometimes known as Indigo Fire) is a modern marvel of tomato breeding, bringing a stunning, almost unbelievable colour combination to your greenhouse that looks as good as it tastes. No blue tomatoes taste as good as the other colours but this one is about the best flavoured blue tomato.

Blue Fire is part of the exciting new wave of “indigo” tomatoes, bred to contain high levels of anthocyanins—the same healthy antioxidants found in blueberries. The fruits are small, elongated, and often feature a distinct pointed end. They start life green with purple tops, but as they ripen, the bottom half turns a blazing red, creating a stark contrast with the deep blue-black shoulders. Unlike some earlier blue varieties which were all looks and no taste, Blue Fire has a sweet complex flavour.

UK Growing Tips

To get the most out of Blue Fire’s incredible colors and flavour in the UK, you need to understand how sunlight affects it.

• Sunlight Equals Colour: The blue pigment (anthocyanin) only develops where direct UV sunlight hits the fruit skin. For the most dramatic indigo shoulders, position the plant in your sunniest spot. If a leaf shades the fruit, that patch will remain red.

• The Ripeness Trap: This is the most important tip: Do not pick them just because they are blue! The blue colour appears early. You must wait until the green bottom half of the fruit turns a deep, vibrant red and feels slightly soft before harvesting. If you pick them when the bottom is still green, they will be tart.

• Greenhouse vs. Outdoors: Like most indeterminate varieties, they thrive best in a UK greenhouse, which helps ripen them fully. However, due to their smaller fruit size, they can be grown successfully outdoors on a sunny patio against a warm wall.

• Standard Cordon Care: As a vigorous vine, it needs stout cane support. Keep on top of pinching out the side shoots regularly to keep the plant tidy and focus energy on those stunning fruits.

Usage & Culinary Notes

• Eat Them Raw: To preserve that incredible blue color, these are best eaten raw. Cooking destroys the anthocyanins, turning the vibrant blue into a muddy brown.

• The Salad Star: Halve them lengthwise to show off the internal red flesh against the external blue skin. They make a standard green salad look incredibly gourmet.

• The Snack Bowl: Their small size and balanced sweetness make them perfect for grazing on straight from the fruit bowl.
