Groundcherry (Physalis spp.)

Perennial broadleaf

A perennial from rhizomes (creeping roots), 8 inches to several feet in height. Mature plants develop a papery case over the berry. Leaves are alternate, ovate in outline, and may be either hairless or hairy depending on the species. Stems are erect and branching and have hairs. Yellow flowers with purple centers are produced singly on the ends of flower stalks. A distinctive papery case (calyx) surrounds the single, round berries. The berries of smooth groundcherry are orange, red, or purple when mature while those of clammy groundcherry are yellow when mature.
