Clammy Groundcherry: Physallis heterophylla
Roots: Deeply buried thick rhizomes.
Flowers: Occur singularly on flower stalks (pedicels) in the region between the stem and leaf, or the region between the stem and branch (axils of the branches and leaves). Petals are yellow with a purple center.
Fruit: A round berry, surrounded by a papery case (the calyx). The berry is yellow when mature.
Identifying Characteristics: Perennial from rhizomes, yellow and purple flowers, stems and leaves hairy, papery case surrounding the berry. Smooth groundcherry (Physalis subglabrata) is similar but does not have the dense (clammy) hairs that are typical of clammy groundcherry. Additionally, the berries of smooth groundcherry are orange, red, or purple when mature, unlike the yellow berries of clammy groundcherry.
