Measured against each other

These two have never been grown in the same trial AMSeed holds. Every difference in the table above is a difference between what each variety's own sources say about it, which is not the same as a difference between the varieties. Two catalogs counting days from different starting points, or reporting fruit weight from different seasons and soils, can differ by more than the seed does.

Disease resistance

Green Zebra

No documented resistance, typical of older open-pollinated varieties.

Aunt Ruby's German Green

Origins

Green Zebra

Bred by Tom Wagner of Tater-Mater Seeds and released in 1983, not an antique, but a modern open-pollinated classic. Chartreuse fruit with darker green stripes and a sharp, bright tang; a chef favorite since Alice Waters put it on the Chez Panisse menu.

Aunt Ruby's German Green

A Tennessee family heirloom from Ruby Arnold of Greeneville, released through Seed Savers Exchange. The definitive green-when-ripe beefsteak: sweet, spicy, and ripe when the shoulders blush amber.
