Also known as Pricklyburr, Recurved Thorn-Apple, Toloache, Indian Apple
Downy thorn-apple unfurls large, trumpet-shaped white blossoms that open at dusk and emit a sweet scent to attract hawkmoths. Soft, velvety hairs cover its grayish-green stems and foliage, giving the plant its signature downy texture and distinguishing it from smoother nightshades. Its nodding, spiky seed pods mature in late summer, eventually splitting open to drop hundreds of flat seeds into the surrounding soil.
