Boy after reading my own post I see that some of it was messed up and didn't make much since in places. I'm wondring if the blue or purple coloring is do to the genetic make up of the tomato because of the concentration of the anthocyanins, which is transfered to the fruit or berry of the tomato as it developes and if it changes the flavor in anyway other than tasting like a tomato? I know its from a wild cross in the first place, which from what I read awhile back the fruit had a off taste which was one of the reasons it has been crossed with different varieties to improve the flavor. I hope that this post is better than my last, I have to take some pretty strong medication evey day, so some times I'm a bit off the mark. George w. Z5-6 MO

I think your asking if the anthocyanins are produced and then moved around in the plant like hormones or nutrients do.
the anthocyanins are produced where they express. It is largely a genetic response to light but can also occur from wounding.

Thanks Kctomato, the more I read about it, the more questions I have, and the more photos of it I see the more I want to try one. I guess I will have to try and get a couple of seeds at some point and grow my own. That would at least answer a couple unasked questions. I hope that some one still has a few seeds, I know that the color of the fruit would be enough to blow most people's minds. George W. Z5-6 MO

So far I have five of the OSU standard sprout and three of the OSU large sprout although one of them don't look like it will make it. and if they survive my care I hope to have some seeds for next year. Attachments:

I'm growing out about 50 standard OSU plants for seed this year and then four of my OSU crosses. There should be plenty of seed circulating by this fall if all goes well.

Hi alan, i think i will most likely be looking for some of the true Blu tomato seeds this fall as I'm hooked now and can't get them out of my mind. We got hit hard by hail today and 3/4 of my garden plants now lay in broken pieces(SOB!) It could have been much worse as some got hit by a tornado in some parts. I will have to start over and hope that I have enough seeds. It looks like I will have a late garden this year at best. George

They will not turn very blue in the greenhouse. Plant one plant outside, you will see the difference. If you grow them in a sunny spot, they will be really dark blue

It's high light and cool temps which make the foliage express.
At 39°N lat, once the summer heat kicks in the foliage color disappears.

Hi-Angel, it is far too late to sow any seeds of them for this year , but if you contact me at the end of the season I can send you a bunch of seeds to get you started,
Barely any of the OSU Blue seedlings will show their blue colour if they are grown in a greenhouse-in fact right through until almost the end of July before any colour shows on the fruit-however if the seedlings and young plants are exposed to cold temps the colour comes to the stem and leaves fairly quickly.
At times on a really good bunch of seedlings of it, about two to three weeks old even in a greenhouse -(cold greenhouse) the best ones in the bunch will show a violet to purplish stem and also purplish colour to the underside of some leaves, these are usually the ones to pick out to work with and cultivate, but not all the seedlings will show this early colour and yet they still go on and produce blue fruit just the same at the end of the season.
For the average person the best coloured ones becomes more apparent after you have potted them up into their final pots and when planting out date arrives-stand the pots outside for about a week to (chill out) so to speak, the bluest ones will then show off their true colours and the stems and undersides of the leaves will darken and become a deep purplish colour and if you are really lucky you might get one or two with the blue on the tops of the leaves as well-its actually quite a tricky plant to learn how to get the best out of it.
I am not quite sure how (Cortona) will fair with this blue colour business, as he lives in a much warmer country than most of us do, and might not have cool enough nights to bring out the best of the blues, so barring late frosts it may be best if he stands them outside in the cool air when there is going to be no frost forcast.
