This should be a climbing bourbon. (Climbing I'm sure - 15 feet in 1 year) with bloom form very similar to Boule de Neige but little less formal. Very white petals, musky delicate scent. I'm trying to id it among the seed sisters of Boule de Neige, but I wouldn't like to reduce the field so much. Could you pls. add any name? During its first flush blooms come in small sprays, then in autumn sprays are very big.

I'll post this question in the ID forum also.

Thanks.
