Cossack Pineapple ground cherry will traditionally ripen later than all other varieties, yet it is a heavy producer of dark gold large-sized fruits that are flavorful and sweet. In fact, these ground cherries taste like a cross between a pineapple, a blackberry and a tomato. In herbal medicine, ground cherries have been used to treat asthma, dermatitis, hepatitis, malaria and rheumatism. They also have been found to have some melatonin, which helps improve and regulate sleep and prevents migraines. If you want to enjoy the flavor and nutrition ground cherries offer, you can simply (once they are fully ripened) harvest them, remove their papery calyx, wash them, and pop them right into your mouth.
