I grow this in Zone 9, Palo Alto, CA. Grows on its own roots, espaliered on a north facing wooden fence. Very vigorous in growth and blooms. It covered a 12' wide space in two seasons and canes are arching over the 6' high fence. Main flush of blooms starting at the beginning of May and lasting two months into the 1st week of July. Blooms are as described. I can't detect any fragrance. Some rebloom in the fall, not as strong as the initial flush. It looks nice with Baby Blanket (a combo recommended by Vintage).
