It's a difficult thing sometimes to single out a specific cultivar. It's not one I stock, but suggest a search on the RHS Plantfinder.

Thanks Worthy1 for your message. I have just been through the plantfinder again to no avail. I can only hope that one of our kind members somewhere can help me out on this one.

Have you tryed to type into google as there are lots of pictures of them and also nursery. hope this helps.

Hi Blue moon1 thank you for your message. I have tried googling for this plant I have even tried to obtain it via the RHSnursery Wisley. I have to agree there are many mentions of the plant on google but none available to buy. I guess I will just have to give up my quest for wanting to own this plant.

I have just googled this, came up with norwell nurseries, they seem to have a good few varieties, lewis palmer included, at £4-50 a pot, Derek.

Many thanks Derekm for that information. I will contact them and let you know if I am successful.
