Alba Semiplena does, until late winter, when the birds get hungry enough to eat them

Thanks, Malcolm.

What coincidence. I planted a semi-plena last year! I suppose I'll see some hips next winter. That's great.

Actually, I was looking for an excuse to plant another rose :-) i I was wondering if Rosa eglanteria kept it's hip through winter?

I don't see any hips on the eglanteria. My guess is that somebody ate them. Squirrels can do an amazingly thorough job of stripping some roses. They are much more efficient than birds, which usually manage to miss some to find later.
