If the rind was dark green and had yellow flesh, it's probably a Black Diamond. I like them better than the red flesh ones but you don't hardly every see them anymore.
hoping the hard frost holds off for us for awhile, but if it frost we will dig the carrots and potatoes, will also pick the last of the watermelons so that they'll still be good to eat, they are soooo sweet, i saved seeds from a yellow one we bought last year at the auction, have no idea what kind it is other than its a yellow flesh with seeds, even husband likes it and he usually doesn't care for watermelon.even got a pink flesh one on the same vine, weird, side by side . keeping seeds again this winter too.
