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.

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!!"

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!

Rhododendron sutchuenense also coming into flower here, though not a classic year for flower power due to the long dry Summer last year.

Is it a Rhododendron or an Azalea? Had this one for a lot of years but have never had a label.

[attachimg=1]
Title: Re: Rhododendron 2019
Post by: Maggi Young on April 09, 2019, 10:06:34 AM
 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.

Rhododendron keiskei 'Ginny Gee' or at least I think it is but lost label so it might have been R. k. 'Wee Bee'

Rhododendron luteum (or Azalea?) had this one for a long time so it might have a cultivar name also.

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.

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

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.

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.

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...

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.

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.
