I saw these pretty purple flowers in a butterfly garden, but there was no one around who could tell me what they were. It was late in the day, their Zebra Heliconian Butterflies had already gone to roost, so I don't know how good of a nectar plant it is, but they were so pretty that I wanted to get one. I snapped a couple of photos, put one on my site, and got an email from Linda Rippert letting me know that they're Clerodendrum ugandense, blue butterfly bush. Thanks Linda!
