The translation of the name "UKIGUMO" (Thanks to Yamsi in Tokyo!) "FLOATING CLOUD":

This is Floating cloud, but it is not Rain Cloud. "Uki" means floating, "gumo (kumo)" is the cloud. That are the clouds that are floating in a sky in a fine day happily, not connected cloud, independent one, white, puffy, round ones. We can see these white floating clouds on a beautiful day. Rain Clouds are dark gray for raining, It is not these ones at all. On the Ukigumo, we don't say Rain Cloud.

This vine has beautiful yellow green foilage and light blue flowers with a white throat and lighter blizzard striping. It grows fast and blooms profusely once it gets well established.
