My last David Austin rose, Spirit of Freedom, sadly died and last September. My local nursery said that they don't last more than 3–4 years in pots.
I replaced it with a yellow old-fashioned rose called The Pilgrim: a pure yellow rose with quite large and evening shaped blooms with many small petals that open to form a flat flower. The rose has a lovely fragrance which is a balance between Tea scent and English Rose myrrh fragrance.
The bush is in a large tub at the front of my property which is south facing so it is in full sunlight.
