Thanks for the kind words everyone ! It will encourage me when we start deadheading them ....

Yes John - the one next to Yakushimanum is indeed Percy Wiseman.

I'm afraid the Yak isn't scented Robin but it does have other assets doesn't it ?

It is my favourite, and going by the reactions here, I'm not alone with that point of view. I've put you on the wrong foot with the captions 'Tuinzichten' which is Dutch for "Garden views" - a caption I use for the more general pictures. And I agree with you that the Rhoddies fit in well as background for a rock garden. The lavender one and the magenta one are some 20 odd years old and I've never known their names, they were pretty 'common' but they build a nice corner I think.

Luc - Might be English Roseum, Roseum Elegans (the "pinker" of the two) and Catawbiense Boursault, and the red perhaps Nova Zembla. All are grown here but you have access to so many others I am most likely mistaken.

Catawbiense is the one John ! Now I remember - the name Nova Zembla does ring a bell as well, but as I wrote it's over 20 year ago...

Wow Luc, gorgeous. Is your soil very acidic?

Leuke tuinzichten, Luc!

A mere flicker of time in the life of a rhododendron.

It's not all that acidic David - it's a sandy/loam - more sand than loam actually - I tend to add some peat in the planting holes for Rhoddies but I doubt it there's any peat left in the soil now...
Anyway, they seem to like it !

David Nicholson · « **Reply #217 on:** May 17, 2009, 07:18:15 PM »

They certainly do.

Rhododendron quinquefolium fall colour.

First photo after using a brush cutter for four hours non stop. Second taken when the shaking hand syndrome had calmed down.

John, that bark colour is really great - I love the way Betula shows its colours too - but altogether i think the bark and trunks of trees are fascinating - thanks for showing - I would love to more about the rhododendron quinquefolium, whose fall colour is so intense

Robin - R. quinquefolium is very slow to set flower buds. From seed it takes at least 10 years or more. I got my plant from the Rhododendron Species Foundation, it was a good size but took forever to have a flower. Someone asked the planstman Hideo Suzuki when it would flower and he said "corky bark, corky bark". Sure enough when the base of mine started to go corky I had the first flower. This species has dramatic bark in old age, corky and peeling. It would seem to need a bit more heat than we can cupply, still it grows on and the autumn colour is indeed exceptional. It will become almost tree like in its native Japan. The new foliage is spectacular, green with a red edging - just visible in this poor shot.

John, your Rhododendron quinquefolium is beautiful, such a brilliant red. The trunk and bark remind me of some gum trees, just wonderful.

Helen - Not many gum trees down this way!

... there are black gums and sweetgums around town but I guess they don't count.

The colour of quinquefolium in the fall is hard to define, sort of a smokey or matte red/pink, I think of crushed raspberries soaked into a white shirt.

Thanks John for your full description of R.quinquefolium - it sounds a wonderful Rhododendron and such an interesting story behind its flowering.
