As the title says. Some years back I grabbed a few seeds from a Morning Glory that a friend had growing up his back fence as a weed and planted them. Predictably, I am still trying to eliminate the plants from my yard.

They certainly do look like escaped ornamental Morning Glory with "Heavenly" blue, white, or variegated blue and white flowers. I also see these same Morning Glories growing in other places.

Are they, in fact, escaped Ipomoea tricolor? Would trying a few immature seeds hurt me?
