Very pretty, but are you sure it's Clitoria ternatea? The flower shape is significantly different
http://toptropicals.com/cgi-bi... and they aren't in clusters. The leaves are not the same from what I can see from your photo.
Are you sure it isn't Lathyrus latifolius, the Perennial Sweet Pea?

Just wondering as my Clitorea ternatea doesn't look at all like yours.
