My final mention is something I would like to have seen but must be selected purely from photographs. Some years ago, I attempted to buy 'Isobel', a single red HT raised by McGredy, but it was unavailable from the only supplier listed in Find that Rose, and has never appeared in their catalogue since.  I've never seen it growing anywhere either so if anyone out there knows of a source of supply perhaps they'd let me know.

Every now and again a single arises in the highly evolved modern strains of roses; early in the twentieth century we had the Irish group of single hybrid teas, including the exquisite ‘Irish Fire-flame’, Isobel, and others, in which the rolled petal of the Hybrid Tea was revealed in a new beauty from the opening of the fluted bud to the starry flower.
