    Sorry friend. You imply it has yellow flowers. Try a search under Rhododendron luteau.

    There are 1000's of species of Rhododendrons and many many man made cultivars and hybrids.
    Even with flowers it might be impossible to provide an accurate id.
    Even experts in Rhodos struggle to id plants with the plant in front of them.
    Time of flowering, hairs or lack of hairs, size and shape of leaves, inudendum or not, shape and size of flowers,...all are needed to attempt an id.

    Without flowers...not a hope. Sorry.

    I can say very confidently that your Rhodo is evergreen, which rules out the deciduous Rhodo luteum... known by the common name Azalea luteum.
    Quote wiki.....
    "Rhododendron luteum, the yellow azalea or honeysuckle azalea, is a species of flowering plant in the heath family Ericaceae, native to southeastern Europe and southwest Asia. In Europe, it occurs from southern Poland and Austria south through the Balkans and east to southern Russia; and in Asia, east to the Caucasus.

    It is a shrub growing 3–4 m (9.8–13.1 ft). The leaves are deciduous, 5–10 cm long and 2–4 cm broad. The flowers are 3–4 cm in diameter, bright yellow, and strongly perfumed, produced in trusses of 5-25 together. The fruit is a dry capsule 15–25 mm long, containing numerous small seeds."

        I bow to my Hon. friend's vast and valuable experience. My previous comment related to the Latin quotation, lutea, meaning yellow.
        Yes. the rhodos also include what we call azaleas. If I may. Perhaps anb instant idententifier might be the leaf shape. Our friends photo was that IMO of a rhodo. The Azaleas have a more softer and totally different shape and appearance. Never mind SS, I totally agree. Even expert growers can't tell the difference. Best wishes SS.

        If it was only as easy as that.
        Apologies my knowledge is very low on the subject.
        All Azaleas are Rhododendrons.
        But not all Rhododendrons are Azaleas.

        I know Azaleas with evergreen leaves that look exactly like a Rhodo.
        Flowers that look like Rhodo but are Azalea.
        It is all to do with the number of stamen.
        Rhodo's have 10.
        Azaleas have 5......but are still to be called Rhodo.

        1. Rhodo Kathleen..5 stamen..red blobs....an Azalea.
        2. Rhodo megeratum Bodnant...10stamen..Rhodo.
        3. Rhodo lipidostylum 10 stamen..a Rhodo.
