Took a long time to grow. Started in a pot in May. Earthed it Late June. Vine finally took off in July. Began blooming early Aug. one or 2 blooms a day. Now it has 50 or more a day. Huge vine and so colorful. Walker-byers love this one! Last week I had 2 pink ones bloom in the midst of the blues. Will attach pics soon. Similar to pic. posted here.

With light blue to dark blue star spoked blooms this is a pretty morning glory to grow. Blossms are around 4-5 inches across and the folige is a solid dark green. Fast to come up and begin vining. I am told this is a good one for hanging baskets but my vines were pretty long and I didn't think it would have been suitable for baskets.
