maybe it depends on where this rose is grown, but on the basis of the one exemplar in my garden i would describe it as " spring or summer flushing with scattered later bloom". i´ve known this one for seven years and it has never shown any new growth earlier than three weeks after the last flower has faded in the middle of july.

Charles Austin is a delightful rose in this zone. My plant is on it's own roots and has Wintered very well.  I've not experienced many fungal problems here. There was a small amount of black spot this year, but the Spring was very wet.  Charles Austin blooms in flushes, and I wish rebloom was a bit quicker. When it is in bloom all is forgiven. I've had no nodding or weak stem problems with this variety.
