Indigo Rose Tomatoes
« on: August 02, 2018, 07:37:50 »
We have grown what looks like a possible good crop of the Indigo Rose Tomatoes both in the greenhouse and outside. However, they have been black for a long while now but show no sign of the bottom of the fruit turning red.

Has anyone had experience of growing these tomatoes and if so does it take a very long time for the fruit to ripen and turn red at the bottom of the fruit?

Yes it does take rather a long time for them to ripen.  But you do want them fully ripe.  When the fruit softens and has quite a bit of red is the best guide for ripeness.   :wave:

I'm still growing PSU blue which gave rise to the indigo series.. unless I am mistaken... the last really long into the season, when others have finished so don't grump at them being slow!

Yes Indigo Blue is a tight selection (more uniformity) from OSU Blue, the best being the 20th plant of the cross.  My OSU20s are a little smaller than Indigo Blue (which I also grow), but otherwise very much identical.  Oregon State University did the original cross between a tomato and an edible blue solanum berry that is a distant relative, but obviously capable of being crossed. 

It was bred to contain anthocyanin, which has the same health giving ingredients as blackberries and blueberries.  Now we have quite a number of 'blue' tomatoes that are all derived from this one.
