pineapple broom: Cytisus battandieri
I have a Cytisus battandieri about 3 years old. It is doing well, not over-watered or over-fertilized. However, it has never set flowers, which is one of the main reasons I planted it. A friend also has one that is flourishing, but has never bloomed. I saw one blooming last summer at Portland Nursery, so I know they can bloom here.
Does anyone have any knowledge of or experience with this plant in our region? What could keep it from blooming?
Thanks, as always, for sharing your knowledge.
