Anne,
I was going to post this in the Plant I.D. forum eventually, but seeing your photo of I. carnea - Bush/Tree Morning Glory has caused me to sneak it in here. I saw this growing in Arenal, Costa Rica. The size of the plant and bloom made me think first of Hibiscus, but the actual look of the blooms and foliage recalled Ipomoea. Do you think this might be the same? I need to check out the growing requirements for carnea.....
