I should say the Sorbus isnt mine.

[Lesley Cox]

The golden fruit is superb Mark. Is 'Joseph Rock' a hybrid or just a good form of a species (which?) Does the seed come true or fairly true?

[mark smyth]

S. acuparia, Lesley.

[Lesley Cox]

That surprises me a little as I though 'JR' was a plant from China (no, I'm not confusing it with the paeony whereas isn't S. aucuparia the European mountain ash and Scotland too?

[mark smyth]

I asked someone and that was the answer but looking up Plant Finder it is listed without a species name

Re Sorbus  Joseph Rock
According to Hugh McAllister   sorbus expert and author of the Botanical Magazine Monograph on the genus, S.Joseph Rock is likely to be a hybrid of S commixta which it resembles, in being fastigiate with smallish fruits and finely toothed tapered leaflets . The other parent is possibly . he writes,  S monbeigii . It is said to be very susceptible to fireblight  [ Envynia amylovora   a bacterium ] in the south of England. The specimen I grew in Cumbria was at least 30 years old and healthy and huge  so sadly it was too big to transplant when we came north to Ross- shire so we have had to buy a young one and start over again.

Re Ranunculus ficaria   El Dorado   
In answer to Mark's query about sharing this celandine    I have a good stock plant in the open garden and two small potted offsets  . There are seven celandine collectors already recorded as being on the waiting list!!!!!!!    I'm trying hard to cultivate it to its optimum.

[Gwenblack]

More about Sorbus Joseph Rock   Most seedlings from isolated specimens are very similar to the parent according to McAllister but a few that I grew from seed were of a more orangey yellow  not the pale primrose.   Of course the garden was full of other rowans  so my seedlings were likely to be crosses

Am I number 8

[Gwenblack]

Sure Mark   Why not,  if you think you will last that long.  Hope so ! 

[Lesley Cox]

Gwen, thanks for that about Sorbus 'JR.' I think I may be able to buy it at a local tree nursery, so will try for that as I love these plants. Having red, orange, pink and white species, it would be good to have a yellow as well.

I'll swap you for a bit of this one. No name yet and I'm open to suggestions. These photo were taken yesterday

'Top Marks' 

[Lesley Cox]

An excellent suggestion Robin, or just 'Top Mark.'

[Lesley Cox]

Or 'ReMARKable.'
