Early summer varieties such as "Early Girl" are small, compact and nicely round, their size and shape indicative of their late May/June harvest. Medium reds follow in July, while the main crop of reds peaks in August. At the peak of their growing season, main crop reds are large, round, juicy, sweet and packed with nutrition. Common varieties include Better Boy, Celebrity, and Burpees's Big Girl. Extra large late season reds, including Supersteak and Beefmaster are the huge, sometimes misshapen or scarred varieties that are awesome on sandwiches or in stacked salads. My husband loves these particularly on BLT's, where one thick slice can cover an entire piece of bread.
