Aristolochia macrophylla (durior)

I’ve always thought of this vigorous vine as an old-fashioned plant because I’ve mostly seen it growing around the porches of old brick houses in small rural towns in southern Ontario (where it is native), probably because it quickly creates a thick screen of large, rich green, heart-shaped leaves. Aristolochia macrophylla (syn. A. durior), the Dutchman’s pipe, also has a peculiar but interesting green and purple flower shaped like a small pipe that offers an unusual, but not offensive, fragrance. Plants are a larval host for the beautiful pipevine swallowtail butterfly which gets as far north as Ontario and Oregon. If you plant it, maybe they will come! Full sun to part shade in moist, well drained soil.
