Common ground-cherry

Physalis longifolia, commonly called long-leaved ground-cherry or common ground-cherry, is a rhizomatous perennial herb in the Solanaceae family, native to much of central and eastern North America, where it grows in prairies, open woodlands, fields, roadsides and disturbed ground. The plant produces erect to ascending, branching stems 30 to 90 centimetres tall, ridged or angular and glabrous to sparsely pubescent. The alternate leaves are lanceolate to narrowly ovate, 5 to 12 centimetres long, with entire to shallowly and irregularly toothed margins and slender petioles. Solitary, nodding flowers arise from the leaf axils on slender pedicels; each flower has a broadly bell-shaped, pale yellow corolla 1 to 2 centimetres across, marked centrally with five purplish-brown blotches surrounding bluish to yellowish anthers. After flowering, the calyx enlarges dramatically and becomes ten-ribbed, papery, lantern-like, fully enclosing a smooth, globose berry that ripens from green to yellow inside the husk. Unripe fruit and foliage contain toxic solanaceous alkaloids.
