I've actually had blackspot and powdery mildew problems with this one,
which surprised the heck out of me.

Fru Dagmar Hastrup is an excellent cultivar (notice the Fru, not Frau --
the selection is Danish, so Frau is incorrect).

It blooms from spring until frost, although usually in cycles.  The
flowers are a large, silvery pink about 3" in diameter, silvery-pink
with 5 petals, and set off by yellow stamens.  The flowers do not need
to be dead-headed, giving way to beautiful 1" wide red rose hips (they
look like little cherry tomatoes).  Bees love the blossoms too.

It tends to get prettty broad-rounded and takes a fair amount of space --
I would say 3' high by 5' wide or so.  It's a difficult plant to work
around because the stalks are so incredibly thorny, but it also grows
low to the ground, shading out a lot of weeds and such.

That was the one that I was going to suggest.  :)
