Marlene mine is doing the same it must have been that very humid summer we had ...
Yours is looking very well.
Very pretty the red and white I do that too with the white bougainvillea and the single red poinsettia.
Gwen that is Euphorbia leucocephala commonly known as Snowflake, same family as the poinsettia.
No good if its windy where you live like I did north of Townsville the branches were always breaking
