'Frühlingsschnee'. Kordes, Germany, 1954. 'Golden Glow' x Rosa pimpinellifolia 'Grandiflora'. This has not developed strongly for me; the foliage is of a slightly greyish tinge, borne freely on an arching branches. Beautifully scrolled buds of creamy yellow open to large, loosely semi-double, nearly white flowers. Fragrant. 5 feet
You might want to take a look at the REFERENCES on the rose page. Some of them indicate that the rose is at least six meters tall. Others say six feet. Another says 150 cm.
It could be that the rose is quite variable, or there are several roses in commerce using the same name.
