Physalis viscosa var. cinerascens is a self‐incompatible, herbaceous perennial which occurs in disturbed or open habitats in the south‐central United States and eastern Mexico. The plants are low‐growing and the pendant blossoms are often obscured by the foliage. In Oklahoma the species blooms from April through October. The flowers are yellow with dark purple or brown maculations in the center and a mat of white hairs in the throat. Nectar is produced in small quantities at the base of the ovary and pollen is present in copious amounts. The pollinators are solitary bees which visit the flowers for nectar and pollen. Perdita halictoides is the primary pollinator and is oligolectic on Physalis.
