Ipomoea carnea

This flowering plant has heart-shaped leaves that are a rich green and 6–9 inches (15–23 cm) long.

[4] A glycosidic saponin has also been purified from I. carnea with anticarcinogenic and oxytocic properties.

[5] Another common name is "bush morning glory", but particularly in temperate North America, that usually refers to I. leptophylla.

In Brazil, I. carnea (in addition to other common names) is known as canudo-de-pito, literally "pipe-cane", as its hollow stems were used to make tubes for tobacco pipes.
