Because in some parts of the United States, there are invasive species like Calystegia sepium, Ipomoea purpurea, and Ipomoea indica.
As of 2021, it is illegal to cultivate, possess, and sell most non-native species of Ipomoea in the U.S. state of Arizona, and before January 4, 2020, this ban also applied to native species.
