This is a truly unique heirloom tomato that is green when ripe, although it will develop a blush colour as it softens further. The key is to feel for ripeness, rather than look.

The variety came from Germany but was cultivated in the U.S. by Ruby Arnold in Tennessee. Her relatives always called it Aunt Ruby’s tomato, and the name stuck.
