Introduced or Not Present

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.

Description & Identification

An annual vine that climbs by twining around supporting vegetation or other structures. Leaf shape is highly variable, often heart-shaped but also often variably-lobed, sometimes with abrupt corners, particularly near the base of the leaf, which usually extends well behind the point of attachment to the stem.

Flowers are deep orangish-red, with an orangeish-yellow center and accents, trumpet-shaped, consisting of five fused petals, coming to neat angles creating a neat pentagonal shape.

In North America, mostly found in anthropogenic habiats, including along roads, railroads, fencerows, old fields, and industrial areas.

Faunal Associations

The bright red, trumpet-shaped flowers attract hummingbirds, and are also visited by some butterflies.

There are numerous insects, including several beetles and moths, that feed broadly on plants of the Ipomoea genus; as there are many native species in this genus throughout North America, these insects are found throughout much of this species' introduced range as well.
