A distinguishing property of groundcherries and glodenberries is the calyx (or husk) that covers the fruit. The calyx collectively refers to the sepals that surround the flower, that protect the bud and support the petals. As the flower matures into fruit the calyx surrounds the berry, creating a protective shield that can help deter pests. This mechanism also plays a role in elongating the shelf of the berry. Husked berries may last 5-7 days whereas berries still encased can last a month or longer. An extensive study conducted by Olivares-Tenorio et al 2017 evaluated the factors that determined shelf-life based on consumer preference. One of their main findings was that fruit with the husk significantly outperformed fruit without husks, and that the limiting factor in husked fruit performance was mold presence. Fruits that no longer had their husks experienced rapid fungus growth after 10 days whereas unhusked fruits saw little to no difference in fungus presence.
