Ground cherries (Physalis pruinosa) are not a very well known fruit, but they are easy to grow in the garden. Their small, yellow-orange fruits have a sweet-tart flavor that is similar to pineapple with a faint background flavor of tomato. In fact, ground cherries are part of the same plant family, Solanaceae, as tomatoes. But despite their common name, they are not closely related to true cherries (Prunus spp.). Ground cherry plants look like small shrubs with bright green leaves that have toothed edges. They sport yellow flowers in the summer before bearing fruit in the late summer to early fall that’s wrapped in a papery husk, much like their relative tomatillos.
