Dutchman’s Pipevine, or Woolly Dutchman’s Pipe, is a vigorous, deciduous climbing vine native to the central and southeastern United States. The Dutchman's Pipevine produces 1-2" hairy yellow flowers in mid to late spring that resemble a smoking pipe, giving this plant its most common name. 
The large, heart-shaped, velvety leaves provide dense foliage, making it an excellent choice for covering arbors, fences, and trellises.

Host Insect:
•Pipevine Swallowtail (Battus philenor) – The caterpillars of this butterfly feed exclusively on Aristolochia species, absorbing its toxic compounds for protection against predators. All parts of this plant contain aristolochic acid, which is toxic to humans and most animals.

Interesting Info:
        •      The flowers of this pipevine emit an odor that's not detectable by humans in order to draw in pollinators (small flies) - the flowers are usually obscured by its foliage and not easily seen. The pollination process is complex. Flies are drawn to the flowers, get trapped in the flowers, become covered with pollen, and then are "released" by the flowers after pollination has occurred. After the pollinator escapes, they move on to the next flower, and the process goes on.

Companion Plants:
•Clematis virginiana (Virgin’s Bower) – Another native vine that pairs well on trellises.
•Lonicera sempervirens (Coral Honeysuckle) – Provides complementary tubular flowers for hummingbirds.
•Asarum canadense (Wild Ginger) – A shade-loving ground cover that thrives in similar conditions.
•Rudbeckia triloba (Brown-Eyed Susan) – Adds late-season color and attracts pollinators.

Ecological Importance:
•Butterfly Host Plant: Essential for the Pipevine Swallowtail’s life cycle, supporting its larvae.
•Pollinator Attraction: Flowers attract small insects, particularly flies, which aid in pollination.
•Wildlife Shelter: Dense foliage offers nesting cover for birds and refuge for small wildlife.
•Erosion Control: Thrives in woodland edges, stabilizing soil with its extensive root system.
