Hello Maggi
I've never had mildew in my Rd cinnabarinum I sowed them about 20 years ago. I have had the pleasure to see them in Edinburgh Botanic street and Benmore Botanic street.

I'm glad to hear of your good fortune, Thorkild. It must simply be that the climate here favours the disease.

[ian mcenery]

Your cinnabarinums look very healthy, Thorkild.  I abandoned mine because of powdery mildew attack  some years ago - they never looked as good as yours.

Maggi

I have had similar experiences with these cinnarbarinums but some do survive though most are poor here.

I had heard that Cox's had stopped selling these for the same reason but when I visited the Glendoick garden last week the Trewithen Orange was absolutely magnificent. This is a plant I had never seen growing well particularly at Trewithem where it is a miffy thing. There  were also a few for sale also full of flowers

That is really super, Ian - makes me hungry it's so orange!

Lovely garden Thorkild and superb cinnabarinums and hybrids thereof everyone.

Ian, that Trewithen Orange is unbelievable!

We had powdery mildew on them when we wintered them in the greenhouse - same with thomsonii - but once outdoors during the winter the pm disappeared.

Thorkild,

I wish I could even grow R. cinnabarinum here - too hot! I keep trying and do have some seedlings coming on - wishful thinking.

Some variations of R. alabamense.

'Narcissiflora' may be the first azalea I ever planted. It must be at least 40 years old now and puts on a great show every season.

Last, a good golden yellow R. calendulaceum.

[Robert]

Another R. calendulaceum. Most of the seedlings are good, with lots of variation in flower color.

R. Trude Webster must be close to 40 years old too. It a giant, even after being cut back twice during its lifetime.

Some of the Rh. in flower in my garden just now.  As usual the names of some are missing due to the labels becoming unreadable

Tom,

Thanks for sharing the rhodo photographs.

I'm familiar with the rhododendrons in my garden - for me, that is about as far as it gets.

I like Alison Johnstone. The color appears to be a cream-pink. Is this so? It also looks compact?

[TC]

The colour picture is reasonably accurate.  It is described as peachy amber on the label but it seems to fade to cream pink and is described as hardy.  It has a cinnabarinum in it's parentage and was obtained from Glendoick.  The web site below gives the full details.

Tom  - Is that 'Elizabeth' left mid in the above post and the picture labelled "garden-plants-013"?

New glasses and can't see a thing for 4 weeks now.

[TC]

Yes, that is Elizabeth.  Thanks to the lack of frost, it has flowered profusely this year.  This is Elizabeth 15 minutes ago.....fading but still colourful.  She started flowering 5 weeks ago and the cool moist weather seems to suit her.
A few others in flower or NOT.
The cinnabarinum has been in for 8 years, produces healthy growth but refuses to flower.
The Johnstonianum is JUST hardy here but is susceptible to frost which kills the buds.  Also, to my disappointment, has no fragrance.  I must have got a "dud "clone.
There are highly scented varieties both at Culzean and Logan, both have creamy yellow flowers whereas mine is white.
Tinkerbird is hardy and produces highly scented blooms.
I moved "Winsome" from the back garden round to the exposed front and it seems to have enjoyed the move.  When I bought it the description said that it was a small rh.
It is growing at the rate of at least 6 inches a year and was already taking over twice the space I had allocated for it !

I have not noticed the season has gone on and will have to get to Benmore, Crarae, Arduiane and Logan before the season is over,
I still have to do something with my pictures of the large leaved varieties taken at Benmore and Culzean about 3 weeks ago.
