Thanks Zuzu ... I never know what's what with plant names anymore so it was a bit confusing when I came across Yellow Oleander now listed as C. thevetia. And geesh, I always preview my posts before hitting send but I must have gone back too far when I hit send earlier because that wording was a mess! I went back and edited my post so that it should make somewhat more sense now if anyone comes along and reads it ... except for the last paragraph with T. peruviana now being replaced by C. thevetia.
