'Margaret McGredy' received the RNRS Gold Medal at the autumn show, in the Royal Botanic Garden, Regent's Park, London, on 17 September, 1925. It was described in the Rose Annual 1926 as "probably the sensation of the year. It is quite a new break; although undoubtedly of Pernetiana origin, the Pernetiana blood has been quite eliminated... The foliage is dark olive green, quite free of mildew"... red on the inner surface, yellow on the outer... It could be called "quite a new break" because its leaves were dark, rather thick, firm; whereas Pernetianas more usually had bright green leaves, somewhat thin and flaccid... [Jack Harkness remembers] 'Margaret McGredy' very well, as a definite bicolour, clearly showing its yellow as well as its red colour... the origin of 'Margaret McGredy' [has been traced] to crosses of Rugosa and Cinnamomea... In the American Rose Annual 1935, page 136, [Dr. J.H.] Nicolas gives another detail: "It is not generally known, but some McGredy roses have a trickle of Rugosa blood. I would not have known it myself had not Margaret McGredy sported an almost pure Rugosa branch, curiously enough with a yellow bloom!"
