Woolly Dutchman’s Pipevine, is a vigorous, native North American twining vine known for its large, heart-shaped leaves and unique, pipe-shaped, greenish-yellow flowers with dark purple throats. It’s a popular ornamental for trellises and fences, providing dense cover and serving as a crucial larval host plant for the Pipevine Swallowtail butterfly, but it is toxic if ingested and requires moist, rich soil and part shade.
