That looks nice Mark. Maybe it will grow wider than high.
Maggi thanks for that link. `Margaret' is certainly a glorious thing (as is Maggi of course). I was particularly interested because R. x Tridel `Benendon' is one of my most favourite things and also because Bob Gordon's plant is said to be a seedling from `Benendon.' My understanding is that `Benendon' is quite sterile (mine has never looked like having a seed) and it was only because I swore on my life just about, that it IS sterile, that I was able to import it many years ago. It's widespread in NZ gardens now, all cutting grown from my original importation.
