You can buy seeds -- they are readily available in late winter - early spring or on line. You can get a variety of mixed colors or solid colors, usually bright blue or red, or bi-colors - solids striped with white or white a white picote edge. The seeds are really hard... when I plant them, I use a piece of sandpaper to rough up one end of a seed and sprout them on a soggy paper towel in a saucer of water. It can take 2-3 days or longer, and weeks if you don't roughen an edge. When you plant, don't fertilize or you'll end up with elephant-sized leaves and no blooms. Another similar plant to consider is moonflower (Ipomoea alba) which has fragrant white blooms in the evening that last all night. I plant the two together - morning glories bloom during the day and moonflowers bloom open in the evening. It's a nice combination.

It is in northeastern pa in my garden. We live in the woods, zone 5a. All of it is on the ground with its roots in a hole left behind by a dead butterfly bush. I didn't plant it. It radiates in a circle approximately 10 feet in each direction. It is in full sun. I also see tiny white blossoms.

Virginia Creeper.... If you enjoy your Strawberries, this vine should be removed as it will quickly choke them out. Yes, it's a native plant, but it is an absolute bully and if it takes over an area, it takes years to get rid of it.

I didn't get a photo when I tried your link.
