Solanum physalifolium (Hairy Nightshade)
Family: Solanaceae (Nightshade)
Solanum physalifolium is a white-flowered Nightshade that grows as a weed in disturbed areas on the plains and foothills. Leaves are pubescent and shallowly lobed. In fruit, the calyx covers the base of the berry. The flowers of Solanum spp. arise from the stem in the middle of the internode, which is an unusual characteristic. All Solanum spp. in eastern Colorado are introduced species.

Compare to Solanum americanum, which has glabrous (hairless) leaves and stems and a reflexed calyx that does not cover the fruit.
Compare to Solanum triflorum, which is also white-flowered but has deeply lobed leaves.
