We are dealing with two completely different species here.

Ipomoea purpurea is the common weedy "morning glory".

'Heavenly Blue' is a selection of Ipomoea tricolor.

They can be told apart at a glance. I.purpurea has hairy stems and flower
buds while for I.tricolor they are smooth.

Check out the Ipomoea homepage.

Thanks for the ID.

Heavenly Blue is a named cultivar. I've got the regular wild ones, they
grow everywhere. They don't hurt trees and bushes. If they come up
where you don't want them, just pull them.

We have a wild abandon of purple and pink ones, they are absolutely
gorgeous in the mornings. They bloom from July through frost for me.
