Stefan, Thank you for the identity of Treehuggers plant! I searched and searched and found Cynanchum (Swallowort) whose bloom looked similar and Calotropis whose bloom also had a resemblance but I just could not find an exact match. I still haven't found a photo of a bloom the same color but it sure resembles Periploca laevigata: http://www.floradecanarias.com...
