Well this thread made me go clerodendrum nuts. I had to buy 2 kinds last week. One is the variegated Clerodendrum bungei 'Pink Diamond' and I got a huge Clerodendrum thomsoniae 'Delectum' and now am looking for a Clerodendrum quadriloculare var. brandonii.

Are they all a strict zone 10 plant?

Gosh Rj, your garden journal is amazing. Truly amazing. What an organized soul you are. Now I am on the hunt for lava sand. LOL. I have bought everything lava but that.
