Morning glories are popular annual garden vines because they grow in a variety of soil conditions and in container gardens. The flowers usually last for a single morning and die in the afternoon, although on cloudy days, the flowers may last well into the early evening or night.Collecting and saving morning glory seeds from a vine in your garden, or one you may admire in another garden, is just as easy as growing them in your garden. Morning glories require very little attention in the garden and collecting seeds from a morning glory doesn't take any special knowledge.

If the flower has been pollinated, soon after the petals fade, you'll notice the seed pods begin to swell. These two seed pods are ripe and pulling them from the vine at this time will not yield good results.
If you want to harvest morning glory seeds to plant next year wait until the seed pods turn brown, and begin to shrivel and resemble the seeds pods pictured above.
Ripe seeds are black and hard, you may find some that are tan or white-these I'll usually discard and keep just the black seeds. If you squeeze a seed pod and it is ready to release the seeds it will crumble in your hands. If you apply pressure to a seed pod that isn't quite ready it may be soft or pliable and won't break apart. If you fail to harvest these seeds before winter approaches, you may have a second chance in the spring because they remain on the vine unless disturbed.
