There are two roses named Canary Bird.
This Canary Bird, which is in commerce, is a hybrid of Rosa xanthina or Rosa hugonis. See References.
The Canary Bird bred by W. Paul & Son is a Sweet Briar and appears to grow only in Sangerhausen.
Modern Roses and other references confuse the two Canary Birds, showing Paul as the breeder of the Hybrid Xanthina. Paul's rose is a Sweet Briar with apple-scented foliage and only 5-7 leaflets.
Nigel Pratt of Tasman Bay Roses says this is an early rose with arching branches of bright yellow single flowers...
Harkness Roses says this rose has very distinctive ferny foliage and blood red spines.
