Can you post a pic? This is a variety of Ipomoea I've not come across before.

It can get quite rampant if it likes where it's growing - even here in the Central Valley. If you want it to cover an arbor it probably will, but if that leads to a roof just watch so the tendrils don't start lifting your roof tiles. My daughter used it quite successfully as a privacy fence against the snoopy neighbors... but had to chop it back regularly to keep it from taking over the porch and stairway.
