Re: Rhododendron Sinogrande
Mo - for you - here it is a while back with the two hybrid Rhododendron (one is R 'Fulbrook') planted for their flowers doing their bit.

In addition to R sinogrande (here in flower)

and the hybrids are R macabeanum

and
R pachysanthum

Already the two hybrids are swamping the others and I think will have to come out.

Re: Rhododendron Sinogrande
The pachysanthum is awesome. No bureavii? Don't worry you don't need to answer that. You can disappear and skulk in the background now. I'll just have to love you from afar

Re: Rhododendron Sinogrande
Rothschildii is an excellent alternative. Easier to grow. Leaves are large not as big obviously but still give a good affect. The Plant is more suited for a smaller space. It stays a lot more compact. There is a macbeanum alpine form that does not get big in height and also give you large leaves.

Re: Rhododendron Sinogrande
Very interesting post Steve. My larger one's leaves are progressively getting a thinner proportion as each new set is formed, but they're not the same shape yet, as the pic you posted. Time will tell. In my pic, there's another smaller Sinogrande in the top left. This was bought from a specialist who said it was grown from seed collected on a SBEC expedition. This too, is producing slightly less oval leaves with each set. Interesting to see what happens. When I Google Sinogrande, leaf shape does seem to vary, even on the same plant. Flowering before 20 years on a Sinogrande does seem to send out alarm signals. Great thread. Any more pics welcome

Re: Rhododendron Sinogrande
Interesting, Steve, you seem to be 100% right, regarding sinogrande. A nursery in northern Germany (where I got my Rh. rex rex from) sells sinograndes, that are field grown there. They state they have survived -18°C, the agency for agriculture of that specific federal state does the same. So I guess, they have a hybrid, at least the plants look like this. Early flowering is simply made possible by grafting. There are grafts on lime tolerant roots sold as the INKARHO version. Makes raised beds, peat and such superfluous.

Re: Rhododendron Sinogrande
Interesting comments. I got mine from Hardy Exotics in Cornwall. I have looked at the image they use on their site but I am not good at spotting subtle leaf differences. Mine has been in a pot for about 4 years so has not really grown much. Here is a picture:

Re: Rhododendron Sinogrande
Really sad, that the big leaved Rhododendrons are so seldomly seen, Rh. kesangiae hodgsonii, sinofalconeri, rothschildii, macabeanum, preptum, pudorosum, watsonii and preastans should all be reasonably hardy. But sadly enough they are hard to get.
Glendoick's seems to be the best source in Europe.

Re: Rhododendron Sinogrande
Mo - excellent photos - looks exotic and very intriguing. Sinogrande is another I must add to my wish list.

Rhododendron Sinogrande
Mo - thank you for the two threads posted on 5/30/16 - both very interesting. I am still learning the ropes on this blog and just found your post today. Anne

Rhododendron Sinogrande
Well . . . way back on 5/30/16 I wrote here that I was going to add Rhododendron sinogrande to my wish list. This morning I ordered a 1-gallon size specimen from Gossler Farms Nursery. Here is a photo from the Plant Lust site showing sinogrande at Gossler Farms Nursery. How likely do you think it is that these are true sinogrande?
Will post a photo of the one I receive upon arrival.
