The Physalis Improvement Project

Welcome to the Physalis Improvement Project!


The genus Physalis is part of the Solanaceae family (also home to the well-known tomato and potato) and is home to the edible species of peruviana, pruinosa, and ixocarpa. These species are commonly known as goldenberry, groundcherry and tomatillo (as well as many other regional names). Groundcherry and goldenberry plants produce small edible fruits that range from sweet to tart with a variety of unique flavors. Tomatillo plants produce small to medium sized fruits and have a mild acidic flavor. This project aims to further explore the cultivation Physalis species by crowdsourcing information from volunteer citizen scientists throughout the United States. The Physalis Improvement Project is led by the Van Eck research group and is made possible through funding from The Triad and National Science Foundations.

Project Goals

  • Gather information from stakeholders involved in the production and consumption of Physalis
  • Use information gathered for crop improvement
  • Heighten the visibility of Physalis as a specialty crop
