Stera, I just typed Helianthemum into the search box and it shows a fair few for sale, especially by Burncoose Nurseries. Hope that helps you!

Thanks Shirley. I did find lots on line but not yellow ones with glossy leaves... I've looked at Burncoose as you suggested but its hard to see the leaves on their webpage. i have sent them an email to see if they can help.

Great ... I would imagine they will be of help before too long.

They weren't - all they said was that they stock the six varieties on their web page - just suggested I enlarge the pics so I could see the leaves. I don't think there is what I wanted at all. Sigh...

How about looking at Helianthemums on here, members own ones and seeing if you can find the one(s) you are looking for. That way, you could ask the member where they sourced theirs. Just a thought .....

google 'yellow helianthemum with glossy leaves' you will find loads are on the web

I did that first Scotsgran but didn't find any. The nearest I got was an orange one but as I wanted it to contrast with a red one I already have I let it go by...If you have found any I'd be interested to see the reference? All the yellow ones I found had soft grey leaves, and its one of those I want to replace.

Off to follow up Shirley's suggestion now.

Thank you both for your interest and suggestions. I do find one I'll try to remember to let you know!

I tried blowing up photos of the plants on the Burncoose site and still could not say what the leaves are really like.

No its a problem with photos from nurseries -they just concentrate on the flower. Its kind of you to go to so much trouble Scotsgran. I'd had a good trawl round Google before I asked on Goy. Ben Fada and The Bride are both beautiful but don't appear to have the glossy leaves. I hadn't seen new Moon - its lovely- but I don't think the leaves are glossy. i will email a supplier and ask - might just give in about the leaves as the flowers are gorgeous!
