Gardeners' Notes:


On Mar 3, 2016, PaulBo9 from Portland, OR wrote:

I garden in Portland, OR Zone 8b and this has been a very successful Oleander. Several years ago- when it was just a year old it handled 11F with some die back but recovered fully by summer and bloomed. It blooms for me from June to September. I think its best for a hot location- against a south facing wall for instance. Great flower color.

I love oleaders, particularly the hot pinks with strong, spicy scents. Although common in central Florida, I have struggled to keep them thriving. Lost to freezes, yet neighbors' rebound. And as an experienced gardener, it frustrates me that I have never been able to propagate by any method.

Controlling those hideous orange catepillars requires constant eye for eggs on leaves and new batches of hatchlings. They can strip a plant bear in just days. The butterfly resembles a wasp, but has bright markings. Black body with white polka dots and a red bum.
