Aristolochia tomentosa (Woolly Pipevine)
Also known as Pipevine, Woolly Dutchman's Pipe Dutchman's Pipevine, Common Dutchman's Pipe.
A vigorous, twining perennial vine with large, heart-shaped leaves covered in soft woolly hairs on both sides — giving the foliage a distinctive grayish-green, velvety texture. Features interesting, yellowish-green, pipe-shaped flowers which are typically hidden by foliage The blooms release a faint odor that draws in pollinating flies and gnats.
Woolly Dutchman's Pipe is a larval host plant for the Pipevine Swallowtail butterfly — caterpillars may strip the foliage completely, but plant recovers quickly.
Train it up a trellis, porch post, or fence, where it can climb 20–30 ft. It needs consistent moisture and does not tolerate dry soil, making it a natural fit for moist, part-shade spots along stream banks, in bottomland woods, or other riparian garden settings.
