Morning glories provide abundant, colorful cover to outdoor areas, and they will re-seed themselves and return the following spring without help from a gardener. You can, however, propagate morning glories by seed if you wish to grow them in another location. Harvest morning glory seeds in autumn, and store them through the winter for spring planting. Different species of morning glory will cross-pollinate—separate the seeds and plants of various species if you want them to retain their inherent colors and characteristics.
Gather clusters of morning glory seed pods from the plant. The round pods typically appear once the plant stops flowering and begins to die off for the season, and they are ready for harvest when they turn brown. Pull brown pods from the plant by hand, or clip stems full of pod clusters from the plant with a pair of scissors.
Roll each pod between your thumb and forefinger to loosen the brittle pod casing. Small brownish-black seeds will fall from the pod as you do this.
Remove any leftover pod pieces from the seeds by plucking them off with your fingers, and discard the pods and stems.
Place a single layer of seeds on a cookie sheet or in a flat, shallow container.
Store the shallow container of seeds in a dry area for approximately 1 week. Allow them more time to dry if they still feel damp to the touch after 1 week.
Pour the dried seeds into a freezer bag, and close the seal.
Store the seed packages in a dry, cool area that is not within direct sunlight.
