My Golden Celebration (shrub, Austin, 1992) is a four-year old own-root rose, now easily 10 ft tall.
It is gorgeous in spring, with a profusion of huge, perfectly shaped orangey-yellow blooms with a strong citrus fragrance. They last up to a week in a vase (very long for an Austin) retaining their fragrance for a long time.
I am trying to grow mine as a climber on an arbor, and it does well this way except for about 4 ft of naked canes at the bottom. I prune it as a climber too, cutting back flowering laterals in winter and leaving the main basal canes alone (there aren't that many of them yet).
It has no mildew or rust in my climate, and only a bit of blackspot most springs. Unfortunately, repeat is not spectacular although I have heard from several people that older specimens do repeat reliably. I'll just have to wait and see :).
