I believe the name "Edna Walling" when used, should carry the "double quotes" of a foundling.

This name has been applied to two roses:
1. a vigorous rambler - whitish pink with green tints,
2. a polyantha - pink.

Here is some information on the pink poly.

BERT MULLEY

Polyantha.

Sport of ‘Spring Song’ (A. G. Mulley Pre 1990) ? or ‘Spring Song’ (Riethmuller Poly. 1955) ?

.....The new commercially available Edna Walling Rose differs from it [the climber] in many ways – flowers, leaves, stems and vigour. Propagating was provided by the late Bert Mulley for this new one. The Mulleys had bought a plant of the Ralph Moore rose Renae from Rumsey’s nursery, which when it came into flower, differed from the original. The question remains, was the different one a sport of Renae, or the long lost Edna Walling Rose? ...... When the Mulleys showed this new one to the Rumseys, they said it was not anything they grow or had grown, and suggested that if it was in bloom at the time of the 1988 Conference, they take some to show Ralph Moore who was visiting at the time. He and the Rumseys expressed the opinion that this rose was a sport of Renae. There are enough differences to say it isn’t Renae, and enough similarities to believe it is a sport. The growth, foliage and stems appear identical to the original, but the flowers are smaller and deeper in colour, more double and carry more blooms per head.

p16. Robert Peace: I was very concerned to read in December ‘Your Garden’ an article introducing a new rose called The Edna Walling Rose. I don’t usually buy the magazine so I read the one page article in the newsagency. It was claimed the name for the rose was decided over a few drinks with the author and gardening personality Don Bourke. I suggest you read the article rather than have me paraphrase it here. . Suffice it to say, an ‘name lost’ old rose has been introduced by a Sydney nurseryman under the name The Edna Walling Rose. There is however published precedent of the use of this name for a rose which was a genuine association with the gardens created by Edna Walling in Victoria. The Sydney rose seems not to have any connection with Edna Walling.

P18, Robert Peace ........It is quite easy to imagine what confusion will arise by the introduction of what appears to be a double bright pink flowering, Wichuriana Hybrid with the same name as the lovely late flowering, grey-leafed Edna Walling Rose. I can only suggest the later named rose be renamed or withdrawn pending further research............

P2. We reproduce here a letter written to Mr. R. Engall of Dural, Weona Nursery, N.S.W. from Mr. Peter Cox, which will relieve those people who have been concerned about it.

Dear Mr. Engall, You recently released onto the market a rose called The Edna Walling Rose and this rose and its history was reported in an issue of the magazine ‘Your Garden’. I purchased a plant of Edna Walling at a local garden centre early this year and the rose now stands around 1.3 metres tall, It is not as described, a climbing rose, although it appears that it can be trained as a pillar rose, as it does not put out climbing shoots. I have also in my garden a plant of a registered polyantha rose called ‘Spring Song’, produced by the rose breeder Mr. Frank Riethmuller of Sydney around twenty years ago. [note - ‘Spring Song’ was reported as being registered in the Australian Rose Annual, 1955, page 128 - Patricia] A close comparison of the Edna Walling Rose and Spring Song has shown these two roses to be identical. In the description accompanying the photographs in ‘Your Garden’ magazine, the Edna Walling Rose was described as a climbing sport of the hybrid multiflora rambling rose ‘Renae’. This [polyantha?] rose was purchased by the late Mr. Bert Mulley from the Roy Rumsey rose nursery at Dural. It seems to have been overlooked that the rose ‘Spring Song’ has appeared in the Rumsey rose catalogue for several years. The rose that you have named the Edna Walling Rose in conjunction with Mr. Don Burke would appear to be an already registered rose, ‘Spring Song’. Further, there is a rose currently produced by some growers in Victoria registered under the name of Edna Walling. [In my indexing of The Australian Rose Annual I have never seen notice of any such registration. – Patricia] This rose is a semi-double pale pink rambling rose. As it appears that the name Edna Walling is already registered for a rose produced by Victorian growers and the rose that you have called Edna Walling is in fact an already registered rose, ‘Spring Song’, it is suggested that your rose should be marketed under its already registered name of Spring Song, in order to prevent confusion. In addition to the article appearing in ‘Your Garden’ magazine, there have been articles and letters published in other journals concerning your rose called The Edna Walling Rose: The NSW Rose, Heritage Roses in Australia journal, the Australian Garden Journal, and the Greenleaf Garden series Colourful and Fragrant Gardens. It is proposed to send this letter to the editors of all five of the above journals, asking that either a copy of this letter be published or that a statement be made to the effect that, the recently released Edna Walling Rose is, in fact, Riethmuller’s rose ‘Spring Song’. The rose names ‘Edna Walling’ and ‘Spring Song’ would appear to have been registered and described by the then Registrar of Rose Cultivars, the late Dr. A. S. Thomas. It was in response to a request by the editor of Heritage Roses in Australia that the undersigned has written this letter.

p31. Philip Sutherland, Golden Vale Nursery. The Edna Walling which was named in New South Wales and is often grown as a feature standard is also known as Bert Mulley. This latter rose is a bright pink polyantha type which bears such a strong resemblance to Frank Riethmuller’s Spring Song and its German parent, the not-as-difficult-to-say-as-it-looks Gartendirektor Otto Linne, that its supposed relationship to Renae must be seriously questioned.

1998 Botanica’s Roses p114 Bert Mulley. [incorrectly] Syn ‘Edna Walling’. Modern, polyantha, medium pink. repeat flowering. This shrub rose grows to 5 ft (1.5m) in height and width and produces airy clusters consisting of 5-20 rose pink flowers freely for many months of the year. The foliage is small, abundant and soft green in color and the bush is absolutely free from disease. ‘Bert Mulley’ makes an excellent hedge and is good for planting in groups; it is one of the best Australian raised roses. The plant always looks neat as the foliage is very close joined on the stems. It was named after a great rose grower and exhibitor and judge who lived at Camden in New South Wales, Australia.
