This variety was bred by Minnie Zaccaria, a home gardener who crossed two heirloom tomatoes to create Big Zac. True to its name, it bears enormous 4 to 6 lb. fruit, and is a high quality tomato in every respect - meaty and delicious as well as disease resistant. We are proud to offer this legendary heirloom-hybrid so you can enjoy its luscious flavor and maybe even win some bragging rights of your own. Indeterminate. 80 days.
