The eyecatching colors of these green and yellow berries caught our attention while my friend Alyssa and I were wandering the trails at Hammock Park last month.
The leaf shape and fruit color was slightly reminiscent of some type of citrus but since it was so low-growing I quickly discarded that idea. Instead, with the help of an internet search, I learned that it’s actually a tomato relative, Twoleaf Nightshade (Solanum diphyllum).
As with most of the “poison apple” family, it’s highly toxic. The plants in that family developed their toxicity to prevent being eaten by wildlife. While effective, the bitter taste and poison means that animals don’t help spread the seeds (which is a major force in propagation and plant species survival).
The edible tomato plants evolved a unique solution to this problem. While ripening, the poisonous glycoalkaloids are rendered harmless as the fruit reddens. Scientists still haven’t pinpointed when or exactly how that happened but I’m glad it did, because there’s nothing better than a juicy, vine-ripened tomato! Well, maybe with a little fresh mozzarella, basil, and a drizzle of balsamic vinegar…
