Quick answer
If you want a large, sweet, green-when-ripe tomato with outstanding flavor, choose organic 'Aunt Ruby's German Green' seeds. This heirloom variety suits gardeners who enjoy watching fruit change color and want something truly different from red tomatoes.
What makes 'Aunt Ruby's German Green' special?
Despite its German name, this tomato was actually cultivated by Aunt Ruby Arnold in Tennessee and became a beloved American heirloom. The large green fruits are prized for their complex, sweet flavor – often described as tasting like a mild, fruity tomato with a hint of spice. Because the fruit stays green when fully ripe, you must learn to judge ripeness by feel (slight softness) rather than color.
Trade-offs to consider
The main challenge with green-when-ripe tomatoes is knowing when to harvest – they don't turn red, so beginners may pick them too early or too late. The plant can be vigorous and may need staking or caging. Flavor is best in full sun with consistent watering; stress can make the fruit tough or bland. Seeds are organic, which may require slightly more care in germination than coated conventional seed.
Key decisions for buying and growing
- Choose this variety if...: You want a unique, sweet green tomato that stands out in salads and salsas, and you appreciate the story behind an heirloom. It's also great if you enjoy sharing unusual produce with friends.
- Planting timing: Sow seeds indoors 6-8 weeks before your last frost date. In most Australian climates, this means starting in late winter (August) for spring transplanting. Mark your calendar – starting too late reduces harvest window.
- Judging ripeness: When the fruit yields slightly to gentle pressure and the skin takes on a slightly yellowish or amber blush, it's ready. Do not wait for red – you'll miss the prime flavor. The first fruit might be a test; pick early and taste to learn your preferred ripeness level.
