I planted a Indigo Rose or " blue indigo" too. First time growing it. I am also trying black cherry again. Last year the " black cherry" plant I got was cross pollinated and not true to type. It turned out to be like a brownish red/ pear type. Loads and loads of fruit, but so tough, dry and bitter even my chickens avoided them! I couldn't believe there was actually a tomato that chickens didn't like, LOL. Apparently I wasn't the only one to have problems with the black cherry, about 1/2 of the reviews from the nursery the plant came from reported that their plant wasn't true to variety. I bought my plant this year from a different source
I also planted a Nyagous black tomato. I loved this variety two years ago...yummy, rich, almost smoky flavor with loads of fruit until frost. But, last year my young Nyagous plant was dug up and killed by my dog and I couldn't find another one

hopefully this year I have better luck with my black tomatoes
