Beefsteak Tomato
Aunt Ruby's German Green stands as one of the most spectacular green beefsteak tomatoes you can grow, with massive fruits reaching up to 1 pound that display brilliant neon-green flesh with sweet, fruity flavor. This treasured German family heirloom was perfected by Ruby Arnold in Tennessee and now holds a place in Slow Food's Ark of Taste as an endangered variety worth preserving. These indeterminate plants thrive in zones 3-10, taking about 80-89 days from transplant to produce their stunning 12-16 ounce fruits that never turn red but instead ripen to a light green with hints of yellow and pink blush underneath.

What makes Aunt Ruby's German Green extraordinary is its brilliant neon-green flesh that delivers a sweet, spicy, and intensely fruity flavor that many growers claim surpasses most red tomatoes. These massive beefsteaks can exceed 1 pound each, making them perfect conversation starters in the garden and on the dinner table. The variety's inclusion in Slow Food's Ark of Taste underscores its importance as an endangered heirloom worth saving, while its German origins and Tennessee perfection tell a beautiful story of cultural preservation through seed saving.
These substantial beefsteaks excel in fresh applications where their unique color and exceptional flavor can shine. Their 12-16 ounce size makes them perfect for slicing onto sandwiches and burgers, while their sweet, spicy, and fruity flavor adds complexity to fresh tomato salads combined with herbs like basil and parsley. The striking green color creates visually stunning dishes, and their robust flavor holds up beautifully in sauces and soups where you want tomato taste without the typical red color.
Sow seeds 1/4 inch deep in sterile seed-starting mix 7-9 weeks before last spring frost. Maintain soil temperature between 80-90°F for optimal germination, which occurs in 7-14 days. Grow seedlings under bright light to prevent legginess, and consider transplanting once into larger containers before moving outdoors.
Transplant seedlings outdoors after all danger of frost has passed and soil temperature reaches at least 60°F. Bury stems up to the lowest set of leaves to encourage root development from the hairy stems. Space plants 24-30 inches apart in rows 36 inches apart.
Harvest when fruits reach 12-16 ounces and display a light green color with hints of yellow and a pink blush underneath. The key indicator is feel rather than color since these tomatoes never turn red. Gently squeeze the fruit to check for slight softness, which indicates ripeness. The indeterminate nature means continuous harvesting throughout the season, so check plants regularly and twist or cut ripe fruits from the vine carefully to avoid plant damage.
As indeterminate plants, Aunt Ruby's German Green benefits from regular pruning of suckers that form in the crotch between main stems and branches. Remove lower leaves as the season progresses to improve air circulation and reduce disease risk, especially during humid conditions. Some growers prefer minimal pruning and simply let the plants grow vigorously with proper support.

“This remarkable tomato carries the story of immigration and dedication across two continents. Originally from Germany, these seeds traveled with German immigrants to America, where they eventually found their way to Ruby Arnold of Greenville, Tennessee. Ruby perfected this family heirloom, transforming it from its German roots into the exceptional variety we know today. The tomato's journey from German gardens to Tennessee homesteads reflects the rich tradition of seed saving and variety improvement that defines heirloom vegetables, earning it recognition in Slow Food USA's Ark of Taste as one of over 200 delicious foods in danger of extinction.”
