Donna, We have tried only two heirlooms, Brandywine and Kellogg's Breakfast, and wouldn't waste garden space on either again. Very low yields and the Kellogg's didn't taste all that great, either. I don't think it was the growing conditions or weather, since our Celebrities and Romas pumped out tomatoes like little factories while the heirlooms sat there sucking up nutrients. I know this isn't what you asked, but consider it the process of elimination!
