Rhododendron luteum

"Yellow Azalea" many Azaleas have strong scent, and are all Rhododendrons. However there are not many scented Rhododendrons that are not classed as "Azaleas" is that very confusing. To add further to the confusion there are evergreen Azaleas generally no scent and there are deciduous Azaleas, most of which are scented.
