Not what you want to hear, but neither. I prefer that my roses have leaves.

"I prefer that my roses have leaves."

And....why don't they have leaves?

I think the implication is that they suffer badly from black spot and therefore defoliate.

Yes, exactly. Here, Mary Rose blooms, drops all its leaves, and doesn't have leaves until next year. I don't have personal experience with Gertrude Jekyll, but its reputation is bad, and its daddy is one of the absolute worst roses for blackspot I've ever had the displeasure of growing, Comte de Chambord. For some perspective, at the time I was growing Angel Face, and it wasn't in the same league.

Newer Austins as much better in regards to blackspot resistance. They have to be.

"Newer Austins as much better in regards to blackspot resistance. They have to be."

That is helpful. I have two Royal Jubilee and have never seen a single leaf with blackspot. But, I have few non-rugose roses and the neighbors are a ways away so risk of transmission is pretty low in my yard.

Gertrude Jekyll. I used to often visit the local botanical garden where Mary Rose and Gertrude Jekyll were grown close together. Gertrude Jekyll always had a stronger and better fragrance.

^^ Oh, those are lovely blooms!

Mary Rose is great here and GJ probably is too although I don't have her. Less BS pressure here.

Voles love MR.
