Karl Förster. Spin. Good reliable rebloom. Moderate fragrance. Habit [diagram] 2. Kordes, 1931. [Provenance: Hortico]. Rather like a white version of 'Stanwell Perpetual' with larger foliage and little scent, this charming rose blooms for many months of the year, yet is almost unknown among growers of old roses, despite its wide availability in North America.

Karl Förster. A cross between 'Frau Karl Druschki' and Rosa pimpinellifolia 'Grandiflora', with pointed buds opening into double pure white flowers with a slight scent. The growth is vigorous, up to 7ft. in height, with attractive greyish-green foliage showing signs of Pimpinellifolia influence. It should, I suppose, be considered together with the 'Fruhlings' series, but it is rather different in character and is recurrent flowering. Bred by Kordes (Germany), introduced 1931.

Roy Shepherd. The ABC's of Hybridizing.
Undoubtedly rose breeding is somewhat of a gamble.....R. spinosissima altaica, for example, has intrigued hybridists for many years as it possesses several qualities that commend it as a parent. Several well qualified breeders have endeavoured to combine its extreme hardiness and good plant habits with the remontant qualities of our modern roses. To the best of the writer's knowledge the combination has been successfully effected but twice. These two exceptions to the usual failures are the white Karl Forester created by Kordes, ('Frau Karl Druschki' x R. s. altaica) and our 'Golden Wings' ('Sister Therese' x R. s. altaica). Both are hardy and both repeat generously. I'll confess that several hundred similar crosses were made before 'Golden Wings' resulted and I assume that Kordes also failed many times before he achieved success.
