The small size over that period of growth does suggest either Intrifast or even straight fastigiatum... which I have a nice shiny leaved form of, quite like Graham's.
I thought by the initial photo that the plant might be rather larger than it really is.

Hmmm, this is why rhodo lovers go to bed with headaches.

Here's 'Intrifast' ex Glendoick shot #1 and as may be a selected form or a repeat of the cross.  It doesn't have that curved shiny old foliage and has remnants of scales.  Also a shot of fastigiatum #2 and the true impeditum #3.  The last two were identified by Cullen himself.  

Maggi - If you look at the fastgiatum shot you'll see the old leaves have a slight curve so a fastgiatum hybrid Graham's may be.  These are a minefield and we haven't  - and won't - even discussed scales, their distance apart or their colour.

Hi John, Maggi and Diane
I have just been out and photographed the leaves of the blie one if that is any help.

Do you agree the first pinky "camp" is too open-faced?

I think that open faced or not, might not give a hint to if it is "true"
Have found so many variations in cw seed .
Here some photos.

The last one is a hybrid  not flat faced
(campylogynum yellow x Tessa Dane)
The first proberly a hybrid and Tessa Dane is (campylogynum (purple! x brachyanthum)

Actually I have been band access to SRGC www by Internet Explore for several month now.
Then EU come up with new rules (microsorft) so I treid out Google Chrome and every thing
are ok again!!!!!!!!!!

Graham  - From the pictures of the new growth in this last posting this lepidote can't be a Lapponica species, I think Maggi and Jens will agree.

Jens    - What variation in the campylogynum hybrids! Even straightish stigmas.  I don't think Graham's plant labelled Myrtyllloides can be correct do you?

Your Tessa Dane is superb.  Tessa must be very proud.

Here the same plant as in picture #2
almost just before it drop the flowers ( a few years ago)
So I think the variaton can be great.

I think You are right about the myrtilloides.

Last photo very short stigma
on a interclon "hyb" of campylogynum.

Flowering at another friend's garden today - R. calendulaceum, the flame azalea and a selected Enkianthus campanulatus 'Showy Lanterns'.  The latter is a really worthwhile plant as is the azalea for late/mideseason bloom.

John,

what a beauty this R. calendulaceum. Not very often offered by the nursery in this area.

Uli - I was impressed with that calendulaceum too, one of the nicest I've seen.  Why the hybrid azaleas are so popular baffles me but it shouldn't.  Abnother good one which is still tight in bud is bakeri and I'll try to get a photo of it in July.  It's ever bit as good.

John,

we have the R. bakeri. But in my opinion it is a very bad example of this species. The colour is a pale orange-red. Looks like the German version of R. bakeri.

Uli - I can collect seeds for you but you realize the seed, as with even collected wild calendulaceum, is likely to give hybrids.  I can cross two goods ones next year at my friend's.  If you need bakeri let me know as it flowers so late it should come true.  He got the mother plants of both species from the Beasleys in the mountains of Georgia  (http://www.transplant-nursery.com/), they are/were famous for their selected forms of the native azalea species - and these are the best I've seen.  In the past my friend's crossed his best calendulaceums together, also best bakeris so he has another generation coming on.

A few Rhododendrons at the Cruickshank Botanic Garden on Thursday night.  It was cold, the light was poor, I didn't have much time and I was eating a sandwich as I wandered round the garden so did not look for names if not obvious.

Two colour forms of Rhododendron kiusianum
Rhododendron leaf gall
New foliage on large Rhodo
Lovely orange azalea

What a lovely soft colour and variation on the colour forms of Rhododendron Roma....Looks like the orange azalea was planted close by and they must make a striking mix. 
The glimpse of the grounds is rather tantalising :D

Robin,
I do have digital pictures of the gardens taken in the last two years, early May and late October only, when I have been taking in plants for the twice yearly bring and buy sales run by the Friends of the Cruickshank Garden.  I've been meaning to post them sometime.  I can't seem to find the time to go in at other times.

I also have loads of slides and prints going back many years but I don't think I'd ever find the time to digitalise them.
