I grew Black Krim one year here in no-rain-in-the-summer land. For me, it produced a whole bunch at once, the first half of the (long) season. The fruit was more perishable than almost any other one I've grown -- it had to be eaten or processed within a day or two iirc. The flavor was pretty good to great, but after I ran out of people to give them to, I cooked some and they were incredibly rich and luscious. So if you can sell your chefs on a fabulous cooking tomato, and you can get a dry summer
, this is a great choice.
On the other hand, I grew it only one year. Does it split a lot in rainy summers?
