ResumoAbstract ‘Henry Kelsey’ rose combines winter hardiness with free and recurrent flowering, high levels of resistance to mildew [ Sphaerotheca pannosa (Wallr. ex Fr.) Lév.], and a field resistance to blackspot ( Diplocarpon rosae Wolf). ‘Henry Kelsey’ is the 3rd winter-hardy climber derived from this breeding program. It is an addition to ‘John Cabot’ (4) and ‘William Baffin’ (5) to which it compares well in winter survival, flower production, and mildew resistance. It is comparable to ‘John Cabot’ in blackspot resistance and length of flowering period, but ‘William Baffin’ is more resistant to blackspot and flowers one week longer. The bright red flowers of ‘Henry Kelsey’ are more attractive than the magenta flowers of ‘John Cabot’ and ‘William Baffin’. Another distinctive feature of ‘Henry Kelsey’ is the trailing growth habit. ‘John Cabot’ and ‘William Baffin’ have arching branches.
