Ground cherry
Overview
A native relative of the tomatillo that produces small, sweet, tropical-tasting fruits enclosed in papery husks. Ground cherries (Physalis pruinosa) taste like a cross between pineapple, mango, and vanilla — an unexpected flavor from a cold-climate plant. They self-seed enthusiastically and are beginning to gain recognition as a potential commercial fruit crop.
