HEIRLOOM. This huge heirloom beefsteak (up to 4 pounds; average 2 ½ pounds) consistently wins taste-tests. Developed in the 1930's by a gardener who planted the four biggest varieties he knew, and crossed one with pollen from the other three. He did this for six seasons and created a variety that produced immense, tasty fruit. He sold the plants for $1 a piece $1,000 a year - and paid off his mortgage in six years!
