The ‘Indigo Rose’ tomato is a cocktail-type variety: it produce bunches of small round fruits that are a deep violet-blue color, nearly black, that lightens to a brown-red hue when ripe. The surprising dark color comes from a particular pigment in its fruits called anthocyane. It’s the same pigment that also gives their color to blueberries and grapes.
The flesh ranges in color from pink to dark purple. It tastes soft and has a strong fragrance. This tomato is known to contain lots of antioxydants. A hardy tomato to the cold that is a vigorous grower, the ‘Indigo Rose’ variety is an easy variety to grow, and you can harvest it over a long span of time.
Sowing for ‘Indigo Rose’ starts in February in warm temperatures, such as a heated germination bed. Another good set-up is a series of nursery pots, which you can start anytime from March to April. In both cases, you should aim for a constant temperature of about 68°F (20°C).
When your new ‘Indigo Rose’ tomato seedlings reach about 6 inches (15 cm), the time has come to transplant them. If you’re aiming to transfer them directly to the growing bed, make sure all risk of freezing is over.
Choose a place for it that is in full sun, if possible with a wall that faces towards the midday sun to lean on.Amend the soil at the bottom of the hole with a little bit of compost and bury the seedling all the way up to the first pair of leaves. Backfill, then stake the plants and water abundantly (but without getting the leaves wet).
The ‘Indigo Rose’ tomato variety is a particularly vigorous one, and it resists the cold better than most other varieties. This makes it quite an easy variety to grow, even in simple, ordinary soil – though of course rich soil that drains well will truly lead it to thrive.
