For Siberian and Russian types, Black from Tula has done well for me for a black tomato, but the standout this year among several Siberian, Russian and Ukrainian tomatoes I’m trialing was Biskaya Roza. This large pink tomato has had great production and was one of my earliest, plus great taste.
In Virginia 7A, most of the darks have been just okay for production, but Barlow’s Best Black has been my most productive dark tomato this year, followed by Brad’s Dark Heart. Even though I’ve grown several darks and many varieties, this is my first year trying Cherokee Purple and it has actually been a relatively low producer and had several tomatoes with rot issues. I’ll have to try it again, since it is just one plant and it could be other variables effecting it.
