Ground cherries, also known as husk cherries or cape gooseberries, are an intriguing fruit that belongs to the same family as the tomato. This family is called Solanaceae, and it includes a diverse range of plants, many of which are commonly cultivated for their edible fruits or vegetables.
One of the most well-known members of this family is the tomato itself. While often thought of as a vegetable, botanically speaking, tomatoes are actually classified as a fruit. They possess seeds and develop from the ovary of a flower, which are the defining characteristics of a fruit. So, in a sense, ground cherries and tomatoes are distant relatives in the plant world.
Ground cherries specifically belong to the species Physalis pruinosa. They are closely related to other members of the Physalis genus, such as the tomatillo (Physalis ixocarpa) and ornamental Chinese lanterns (Physalis alkekengi). These plants share similarities in terms of their growth habits, flower structures, and fruit development.
The tomatillo, for example, is a small green fruit enclosed in a papery husk, much like the ground cherry. It is often used in Mexican cuisine, particularly in savory dishes like salsas and sauces. The tomatillo’s tart and tangy flavor adds a unique twist to various recipes.
Ornamental Chinese lanterns, on the other hand, are prized for their bright orange or red papery husks, which resemble small lanterns. These husks enclose small fruit that is not typically consumed. Instead, they are primarily grown for their ornamental value and are popular in dried flower arrangements.
Having personally grown ground cherries in my own garden, I can attest to their distinct flavor and charm. The plants themselves are relatively easy to grow, requiring similar conditions to tomatoes. They prefer full sun, well-draining soil, and regular watering. Like tomatoes, ground cherries are typically started from seeds indoors and then transplanted into the garden once the danger of frost has passed.
The fruit itself is small, about the size of a marble, and is enclosed in a delicate, papery husk that turns from green to a golden-yellow or purple color when ripe. As the fruit matures, it falls to the ground, hence the name “ground cherry.” The husk protects the fruit and helps to prolong its shelf life, making it a convenient and portable snack.
When fully ripe, ground cherries have a unique sweet-tart flavor that is reminiscent of a tropical fruit, with hints of pineapple, citrus, and tomato. The taste can vary slightly depending on the specific variety and growing conditions. Some people enjoy eating ground cherries fresh, while others use them in pies, jams, or preserves. They can also be dried or frozen for later use.
Ground cherries belong to the Solanaceae family, which also includes tomatoes, tomatillos, and ornamental Chinese lanterns. While they may not be as widely recognized as their tomato relatives, ground cherries offer a delightful and versatile addition to any garden or kitchen. Their intriguing flavor and unique husk make them a fun and rewarding fruit to grow and enjoy.
