I'm trilled after 4 years of searching to have found the name of this very beautiful morning glory. It must be very rare. I bought a package of mixed morning glory seeds back in 2000 and I was graced to have this beautiful plant with the extra small petals at the bottom of the flower emerge. I was just in awe of the flower and its special petals. I tell everyone it is special. Through the years in moving a lot, I have saved seeds and planted this plant each year in a new location. I'm now at a permanent location and these flowers will adorn my fence lines always. It grows very well in East Texas and Dallas areas. Also grows well even in a pot if you have no where to plant one.

This is one I think everyone should grow at least once, they are just sooo pretty, they stay open all day here for me, and even longer into the evening on an overcast day, not a delicate bloom either, it is tough!

This flower looks like double. But new uneven petals grow on outside of original petals to make it look like doubles. Their stamens and pistil are normal. This plant can produce seeds though not in great profusion. All flowers don't have feathered corolla and some flowers are normal 'singles'.
