This cultivar is listed as triploid in the paper 'Pollen diameter and guard cell length as predictors of ploidy in diverse rose cultivars, species, and breeding lines'

A climbing rose that I kept at 4 foot tall and 8 foot wide. It produces magnificent numerous blooms of powerfully scented flowers.

It gets blackspot and will defoliate without spraying.

Fertile as both a seed and pollen parent.

I had a White Dawn for awhile against old, dark brick, with Single Gaiety pinks and sweet william around its feet. After a year or two to establish itself, it bloomed lavishly, looked fabulous and, at its peak, quite literally stopped traffic. I want another one to put in my community garden.

I don't think you can say New Dawn gives more bang for the buck than White Dawn in this climate (on the zones 5/6 line). I do think White Dawn may be one of those older roses with which one needs to avoid chemical fertilizers and use good ol' composted black cowpoop. That's what their breeders used, after all, and this trick has worked for me with other older roses.

Personally, I wouldn't prune it at all except to get rid of dead, diseased, seriously wimpy or badly damaged canes; it blooms on both old and new wood, but especially on old, which is why it takes a year or two to hit its stride.

Would any of you who have it be willing to part with cuttings? I could trade Cl. America, Kordes Perfecta
and/or The Fairy, or would pay a reasonable amount, plus postage. (Guess I also need to check the cuttings exchange, huh?)
