I remember a place we bought some years ago that had a bunch morning glory in the backyard. I tried to control it and get rid of it but it just wanted to take over. I came to think that all morning glory was invasive and obnoxious. Then I read how people bought the plants for yard and wondered about it. There seems to be a big variety of types of morning glory. Whatever the answer is the flower is pretty. This one is growing wild in Delta Ponds.

I checked online and learned that there is a wide variety of morning glories and some are considered invasive. But some report that if one knows how to care for it and when to remove the spent vine and seeds it is no more difficult to control than a lot of other flowers. Seems it might be a reasonable assumption, but I have no idea. I probably will never plant it in my yard.
