This gorgeous plant makes wonderful tropical-looking foliage that absolutely solidly covers what it's growing on. This is fine in the right place. HOWEVER, be very careful where you plant it. Ten years ago I foolishly planted it within six feet of other perennial climbers, and failed to keep a close enough eye on it. It romped right over its neighbors and killed them, and started to eat a six-foot shrub rose. Now I'm struggling to get rid of it. We never saw pipevine swallowtails on ours, or I'd find a way to live with it. It is lovely, with its overlapping heart-shaped leaves, and worth growing if you have a good spot for it. The bottom line: Think twice, even three times, about siting before you plant this.

This particular Pipevine, Aristolochia macrophylla, is commonly found in semi-wooded areas growing up trees here in the midwest and east.
Aristolochia macrophylla serves as one of two pipevine host plants for the Pipevine Swallotail, Battus philenor, in our midwest region. (The other is Aristolochia serpentaria, Virginia Snakewort.)
According to some sources, the Pipevine swallowtail population has diminished since much of the naturally growing aristolochias have been destroyed by development. Thus an effort has been launched to encourage planting of pipevine host plants to forestall continued depletion.
We have this vine in our woods and it is easy to grow. It's a pleasure to have the pv swallowtails visiting our flower garden in the summer.

A. macrophylla is generally grown for its ability to grow fast, climb, and create shade or privacy to an area. It dies down each winter and returns in spring. The leaves are heart-shaped with a rough texture. The flowers are insignifcant, a brownish and cream color, and resemble a Meerschaum pipe. They have a strange, but not unpleasant odor and are attractive to the Pipe Vine Swallow. This plant can grow up to 18 inches per year, and a strong trellis is needed.
