Cossack Pineapple Ground Cherry (Physalis pubescens) is an annual plant from Eastern Europe, distantly related to the Mexican tomatillo. This particular variety was brought to the National Germplasm collection from Poland and was further selected, named and introduced to US gardeners by seed saver and breeder Will Bonsall.
The taste of the fruit is different to that of Cape gooseberry. The ripe ground cherry tastes more like pineapple with hints of cherry tomato and vanilla. Their sweet flavor is what earns them the nicknames “strawberry tomato” and “Cossack pineapple.”
This is a fun and easy crop to grow, with the low, bushy, spreading plants reaching a height of about 30-60 cm. The plant is vigorous producer of marble-sized yellow berries (the size of cape gooseberries) in a husk from midsummer until well into autumn. The fruits drop from the plants when they are ripe, hence the name ground cherry. They are firm fruits, even when ripe, with very small seeds.
