Bonnie Plants "Black Prince" Russian Heirloom Tomato

Very high yield, has grown like a weed! However, mine tend to be a brownish-red (more red than brownish-purple, as I imagine they're intended to be). Also, I've found that these are prone to cracking easily on the vine and bruise easily. When cut open, they remind me of "tomacco" from The Simpsons :p
