At least her flowers are lovely, David - they look so awful when frosted to look like teabags.
It was  the  habit of  frost doing that to mine which lead me to  pass it on to someone with a less frosty garden.

 Perhaps  a feed with  Miracid ( do they still make that?) or  Vitax Q 4   to green up the foliage a bit?  Perhaps  a lot of  nutrients are being washed out of your soil  by all that rain?

Here is  our Rhododendron uvariifolium - which will be on the cover of Ian's Bulb Log  tomorrow - with other rhodos included.



This  gem is also featured in this video from Ian Young

Thanks Maggi, Miracid is still going and perhaps I'll run a soil test on the bed too, I noticed today that one of my other Rhodies looked a bit pale.

Over the last couple of years I've built up a collection of around a dozen small Rhodendrons mainly from Hartside Nursery. All are in pots as I don't currently have anywhere to put them in the garden where they might be happy and they might have to stay that way for some time. Here's the first one to flower, Rhododendron 'Artic Tern'.

Ralph, do you grow most of your big 'uns in pots? Is this is a room issue or a soil issue? Nice collection there.

Very nice - a bit like 'Gigha'.

Today's  (fairly) useless information......

'Gigha' is one of  Oban's "grandparents"   
Oban is  R. 'Grouee ' x R. keiskei  Yaku' Fairy

Colours very similar,  'Gigha' flowers are  flat faced, showing its calostrotum blood while the  flowers of 'Oban' are more campanulate.
@Oban was named  for the ARS rhodo conference in Oban in 1996
