My first of the season and just as the same time as last year.........
Rhododendron praecox
[attachimg=1]
-
Looks great David.
Seems it has increased a lot since last year?
-
Yes, it's done very well, been fed well too.
-
The last week of mild weather has allowed my Rh. Cilpinense to keep its flowers without reverting to brown kleenex - other paper hankies ARE available. I would rather the weather would cool down a bit - no frost please - as many of my plants look as if they would flower within a week if this mild weather keeps up.
-
I have some in flower now.

R. praecox flowering for a week or so now - a month earlier than last year. David yours is looking really good this year.
[attachimg=3]
R ‘Christmas cheer’ (somewhat past Christmas)
[attachimg=4]
R. ‘Ptarmigan’
[attachimg=5]
Pieris
-
Thanks Graham. I like your R. 'Ptarmigan'. Having lost all my pot growing dwarf Rhodies in last summer's heat wave I swore not to buy any more....but I might just get Ptarmigan.

Lovely photo from Julia Corden- SRGC President and Manager of the Explorer's Garden, Pitlohry today
"Rhododendron sherriffii flowering well at the Explorers Garden, Pitlochry - usually hit by a frost or snow this year so mild the flowers are enjoying the weather!!"
[attachimg=1]
The new foliage of this rhodo is great too - and the indumentum beneath the leaves changes from light lime -green to dark cinnamon as the leaves mature. Fascinating!
-
What a terrific colour Sherrif certainly had a good eye.
-
Rh sutchuenense has started flowering in the garden.
-
Rhododendron sutchuenense also coming into flower here, though not a classic year for flower power due to the long dry Summer last year.

Rhododendron lutescens lights up a dark and dreary corner.

Rhododendron racemosum

Rhododendron 'Snow Lady
[attachimg=1]
-
Looking good, David. My 'Snow Lady' is about the same stage. Temperature dropped just below freezing last night but I think she is ok
-
A present from a generous forumist.
R. 'St Merryn'
-
Beautiful colour.
-
Is it a Rhododendron or an Azalea? Had this one for a lot of years but have never had a label.
[attachimg=1]
-
Yes! All azaleas are rhodos, but not all rhodos are azaleas! It is an Azalea in so far as it would be sold as such.
There is usually a distinct "look" to an azalea especially in the flowers and foliage, whether evergreen or deciduous, which identifies it as an azalea as opposed to a rhodo. Azaleas are flowering shrubs in the genus Rhododendron, particularly the former sections Tsutsuji (evergreen) and Pentanthera (deciduous).
-
Rhododendron concinnum, a very small plant I won as a raffle prize quite a few years ago now and flowering for the first time for me.
[attachimg=1]
Rhododendron keiskei 'Ginny Gee' or at least I think it is but lost label so it might have been R. k. 'Wee Bee'
[attachimg=2]
-
Rhododendron luteum (or Azalea?) had this one for a long time so it might have a cultivar name also.
[attachimg=1]
Not sure where to put this one, Cassiope 'Edinburgh'
[attachimg=2]
-
That would be 'Ginny Gee'.

Rh. ‘Joachim reich’ from the middle of March.
[attachimg=2]
Rh. Elizabeth
[attachimg=3]
Rh. (Lost label) any thoughts anyone?
-
Graham - The yellow could be 'Patty Bee'.
john
-
Thanks John. I have a vague memory that the name began with a W (definitely not Wren) but I don’t know why I think that.
-
[attachimg=1]
[attachimg=2]
Rh. Glischrum ssp. rude
First time flowering for me. I bought it as I liked its bristly leaves and stems. I had some problems with it as the stems are brittle and broke off in the wind. Had to move it twice before I found this place for it.
-
[attachimg=1]
Rh. carolinianum ‘Dora Amateis’
[attachimg=2]
Rh. ‘Night Sky’
-
[attachimg=1]
Rh. megeratum ‘Bodnant form’ and St Merryn’

David - These evergreen azaleas are very difficult - nay impossible - to identify save for a few very distinct ones. I'll stick my neck out and say it might be Diamant Purpur, one of a number of German evergreen azaleas in the Diamant Series bred by Fleischman. They are great performers but are not often seen for sale these days.

Graham - I'm fairly certain it's 'Patty Bee'. Glendoick did 'Widgeon' but it's pink, 'Wren' it's not, that would leave 'Wagtail' which I have here and it's almost prostrate, the flowers are quite reminiscent of lowndesii. It can be deciduous after cold winters. Can't recall any other Ws from Glendoick.

Thanks John. I know that I bought it from Burncoose many years ago, I'll have a look at their current catalogue and see if I can find any clues.

David - I should have asked - Have you pruned it at all and are the flowers smallish or regular sized?
If small then Diamant Purpur, if large and the colour is a wee bit off then maybe 'Blue Danube'?
Diamant Purpur is around 2ft high here. Online colour photos of it are very inaccurate.

Hi John, I don’t doubt you are correct, it is a very common yellow and I remember buying it as I wanted a small yellow one for a certain spot in my previous garden. I have no idea why I should think it may have begun with a W.
Thanks.

John, when I referred to my having obtained it from Burncoose I was referring to R. luteum that I had pictured earlier in the thread. The Azalea I have in a rich pinky shade I have had for quite a few years and was probably garden centre purchased. It's certainly not 'Blue Danube', it's not been pruned, and the flowers are smallish and of a fairly regular size. They tend to be a lighter shade of pink towards the tips of the petals so perhaps could be 'Diamant Purpur'?

Despite the losses from last summer's horrendous drought in Copemhagen things are not looking bad at Jens Birck's, in fact I'd say spectacular!
1. R. cinnabarinum v. blandfordiiflorum
2. R. 'Great Dane'
3. R. 'Lem's Stormcloud' x rex
4. R. thomsonii which lost 70% iof its foliage
Chilly, rain, rain and more rain with a smattering of severe thunder.
Luckily no evergreen azaleas to identify. ;D

Rhododendron 'Gartendirector Glocker'
[attachimg=1]
and Rhododendron 'Wren'
[attachimg=2]
-
David, your photo. of R. luteum reminded me of a time, many years ago, when I was on a track in a forest in Perthshire. I could smell something sweet but could not find where it was coming from. Eventually I found a bush of R. luteum in full flower. The scent was wafting for a long distance in the still air.
-
Ian, it is right beside our front door, smells lovely.

Again from Jens Birck's Copenhagen garden What drought?
Rhododendron 'Golden Princess'
Rhododendron 'Ginny Gee'

Lewsia tweedyi in a peat block!

A hybrid by Mogens R., another wizard of the Rhododendron world, R. 'Gedser Gold'. Jens rates this one highly.

13c, sunny and magnolias are out.
-
Gems!!
-
Following Maggi's guidance (in Rhododendron 2016 replies 173-176) looking good. Only a couple of stems to prune out now.
[attachimg=1]
-
The Pieris is jolly well flowered, David!
-
Yes it is. I've had for a long time, cost 50p from the local market. Grows like Topsy ;D
-
Earlier this week I saw a beautiful rhododendron, about 1.5m tall and almost blue. The owner though it might be a form of R. dauricum.
Is this likely in view of the flowering time and colour, and if so which cultivar(s) might it be?
Thanks for any suggestions.

One man's "pinky violet" is another man's "blue" ....... one of the PJM hybrids ?? :-\
-
Agreed Maggi and normally I'm sceptical of such descriptions ;D, but this really caught the eye as near the blue end of the violet spectrum.
Perhaps the soil and dappled shade contributed.

On Wednesday I had a clinic at Aylsham and took a long lunch break/short detour and quick gallop around Stody Water Gardens - well worth a trip at this time of year if you like azaleas, but I would recommend a slow stroll rather than the quick gallop, it is an amazing example of massed planting and the scent was fantastic...

Yes, it is well worth visiting Gail.
-
Already some years old and still only a few centimetres high... Rhododendron nakaharai from the mountains of Taiwan.
-
Rhododendron platypodum is a superb rhododendron that is finally making its way here. It's a stout and sturdy fellow with a blue tint to the foliage. The leaf petioles are hard to see without looking straight dowm at the tips, they're extremely short, broad and wedge shaped. Surely some fine hybrids will come from this one.

Very nice chunky little chaps, John!

Friend Jack's daughter -in-law has just returned home from a posting in Buryatia in eastern Siberia where she shot these dauricums.
I've just returned from a visit to Wrightman's Alpines in the charming coastal town of St. Andrews, New Brunswick, a good 5.5 hour drive from Halifax. Pix later.

22c & sunny
-
Wow! Has there been an element of low-level burning to the trees, do you think. John? There seems to be something that looks like fire damage to the lower trunks. The flower power of the R. dauricum is spectacular!
-
Maggi - Could it simply be more mature wood rather than fire scorching? I presume it 's Pinus sylvestris but I've never seen new wood such a colour usually a coppery orange.

Very possibly, John - I'll be studying tree trunks more closely in future to learn what I can.
