Just thought I would note that I purchased two oleanders last summer ('07) and that they over wintered without protection in Abbotsford on Sumas Mountain. This winter, I intend to burlap them though. I got a little busy in December and didn't do that last year and was scared I would lose them. Because of our excessive rains this year ('08), I did get yellow leaves with black spot, but took those off the plant. Let me know if you are growing oleander in Zone 8 or lower and what your experience has been. I love this plant. It is very showy. I have it pruned like a lollipop at the start of my driveway and it has a twisty trunk, too.
