Seeds from this Ipomoea leptophylla Bush Morning Glory or Man Root. These large very deep mauve rose 3 inch blossoms cover this perennial vine off and on all summer. Six hours of sunshine and letting this dry out occasionally seemed to be the key to the success of this plant. The top of the plant dies off at the first frost, the root is very cold resistant. The root can get up to a foot in diameter and several feet long.
