A 1950s heirloom, 'Ace 55' has excellent, fresh tomato flavor and is a lower-acid tomato. An old favorite for canning, 5″–6″ diameter, 6–8 ounce fruits are just the right size to quarter and pack into jars. Yields are exceptional; as a determinate type, the majority of the fruits ripen over a 1 to 2 week period. In areas with a long growing season, sow in succession.
