why does myLem's 45 rhododendron not flower

Some rhododendrons are difficult to flower - specifically some of the species, but they usually have incredible foliage. I've never heard of the roddy you are asking about and can find no info by googling or checking our heavy tombs of roddy books. I suspect it is a hybrid and that there is another problem causing the lack of flowering.

Are you growing it in acid soil? God humus rich acidic soil? How much light is it getting? A close of of the shrub and a shot showing its surrounds might help.
