Moulden, President of the National Rose Society of South Australia, expresses a high opinion of three new climbing sports which have originated in South Australia. ‘Climbing Mabel Morse’ – A very strong climber, with brilliant custard yellow flowers of exhibition form, and of delightful texture.

New Roses 1931.  Clb. Mabel Morse  (Per.  Moulden 1931) F. 5. A reliable, very free blooming climber of the well-known dwarf variety. Although not so strong a grower as 'Climbing Golden Emblem', the brilliant golden yellow colour and beautiful exhibition form of the blooms should ensure its place as the best yellow climbing rose. It may also be treated like 'Climbing Belle Siebrecht' as a strong growing bush rose, making a very fine specimen. Recommended for dry inland areas as it is liable to lose its foliage and die back under moist coastal conditions. 2/- each.
