Bosque Blue is a striking tomato with fruits shifting from indigo blue to red. This is due to high levels of anthocyanins, which are powerful antioxidants similar to those found in blueberries.
It is a mid-season variety that produces fresh-flavoured tomatoes of 60-90g weight that are nice fresh in, for example, salads or on sandwiches. The flesh is firm and juicy. The flavour is sweet, somewhat complex with a mild tang. Some tasters also notes hints of vanilla in the profile. We find it to be a nice subtle flavoured tomato with a stunning look. It is ideal for a nice presentation.
The growth habit is indeterminate which means that the plant is a climber that will produce until terminated by frost.
Some background
The key parentage line of this tomato is the Indigo line of tomatoes created by a breeding program at Oregon State University (OSU) led by Prof. James Mayers. The Indigo line is the result of crossing wild tomatoes with garden varieties to bring back the anthocyanins and the indigo blue colour.
The indigo line was selected on the basis of the anthocyanin line and some criticised the flavour of the lines as a bit middle-of-the-road. That may be a bit unfair, but the seed saving community took on the challenge to add more flavour and Lee Goodwin and Jan Cunningham of J&L Seeds crossed the OSU Blue with Amy’s Sugar Gem for improved flavour. The result of 5 years work is Bosque Blue. Many say it’s the best tasting tomato of the Indigo line.
There is also an old controversy between private interests and the university breeding programme’s Indigo line. A European large seed company is rumoured to have gotten hold of seeds from the OSU program early on and went on to create their own cross without any reference to the OSU Indigo. They patented and protected DNA sequences from anthocyanin rich tomatoes as their invention. However, the move caused an uproar within the EU and the patent was voluntarily dropped by the seed company. While the case is closed now, growing and saving seeds from Bosque Blue and other Indigo tomatoes strengthens and verifies the commons rights to these seeds which we find important.
