Hi (Please see attached pics) I bought a Rhododendron last year from a local garden centre, but have no idea what species it is. Can anybody help please? Also, I bought a Golden Gate this year, and when it had finished flowering (was in flower when I bought it), it appears that there is some sort of disease affecting the leaves. Does anybody know what this is? (Thankfully it has a guarantee so I can return it). Thanks for your help.
