Nola Simpson and John Ford. Breeding for Chocolate Brown Colours in Roses.
.....New greyed orange brown strain. In the 1980s the picture changed with the introduction of this more vigorous strain and a complete new line of breeding. Important cultivars include Mary Sumner, 'Colorbreak ('Brown Velvet') (MACultra) and 'Hot Chocolate (SIMcho). These roses are all noteworthy for their vigour and health and they pass on their attributes to their offspring. 'Mary Sumner' proved very useful in producing brown shadings. It set seed easily but a number of the seedlings grew in an unruly manner and threw long growths, especially in the autumn.....In the mid 1970s the rose 'Mary Sumner' was introduced into the breeding programme to bring more vigour into the offspring and also to set seed readily with different pollens.

....Mary Sumner has proved a fine breeder of healthy roses. What is interesting is that I would call both 'Mary Sumner' and 'Arthur Bell' "unmanageable" because of their tendency to throw over-tall semi-climbing second shoots.

Final Analysis 1983-84.
Mary Summer. McGredy 1976 (Seedling X Seedling) 3" diameter, 15 petals, orange-red, slight fragrance. 20 reports, 7.5 rating. Mary grows, let me say, well, too well for the rose garden, she is a shrub rose. In warm to hot weather she blooms very well, making a grand sight, and the repeat is very good. She is healthy and grows well. Recommended.

Mary Sumner McGredy 1976 [('Orangeade' X 'Margot Fonteyn') x ('Elizabeth of Glamis' x ('Little Darling' x 'Goldilocks'))] 5 reports, 5 years, 5', 5.7 rating. Orange Salmon. This should be grown as a shrub rose these five reporters say, otherwise it falls all over the place and needs staking. It makes a good large healthy shrub. The colour is bright and repeat good. There is a perfume.

Don Sheppard. Review of Newer Roses 1981-82 Season.
Mary Sumner (McGredy '76). Seedling x seedling) Orange-red. 3 reports, 4 years. 5'6". 7.5 rating. This rose two reports say should be classified and used as a shrub, as it's very tall. South Taranaki says lovely bright blooms are a little on the small side, Manawatu finds it healthy and Hastings evidently has a poor bush.
