Beefsteak tomatoes (Solanum lycopersicum) are meaty, juicy fruits perfect for summer sandwiches or as sliced snacks with a sprinkle of sea salt. Large, thickly fleshed beefsteaks are the biggest type of tomatoes, weighing 1 pound or more. Growing quickly to at least 6 feet tall, the late-maturing tomato plant will produce a bountiful harvest in about 85 days. It needs a sturdy cage, trellis, or stake to support its fruit.  (www.thespruce.com)
