Ipomea macrorhiza is an extremely rare species of tuberous, night-blooming morning glory native to the Southeastern United States.[2][1]
This is a vigorous vine with stems growing up to 20 feet long. It has large, tuberous roots and white-and-pink flowers that bloom at night.[2] The leaf shape is highly variable, ranging from triangular to palmate.[3][2] The seed capsules contain 3-5 pubescent seeds.[2]
This plant is rare and so is not widely cultivated. However, its roots are edible and the plant was cultivated by Native Americans as a food source.[4] I. macrorhiza is also of ornamental value due to its attractive flowers.
