I once grew Waltzing Matilda. Between 1968 and 1998 I purchased many roses from Jock Jack. He had a nursery at Wishart and then further out, about ten kms to Rochedale. I liked Gladys Moncrieff. Peter Jack took over the nursery.
The description of 17 -25 petals is a bit at odds with Christian Dior’s petal count of 45 – 50, along with the downloaded image. I agree with WG Treloar’s comment about stripes and pink flecks that there lacks “enough variegations to be distinctive” in the blooms produced by the WM I grow. This rose came from Thomas For Roses.
Jock Jack not John Jack was well known to Morrie Duce. Morrie Duce has been a leading light in roses in Brisbane for a very long time. I would go with his 1996 description. He has been a judge for possibly more than thirty years.
Thanks for your response Bonbon. I don't disagree. I assume the W G Treloar was the founder of Treloar Roses so it is fair to say he was describing the Jock Jack find. The query I have is petal count of only 17-25. MR12 does not list a count and I cannot find a reference to the number. Can you remember if your rose had as few as 17 petals? The second issue is the streaking/flecks and how pronounced this was. Like other roses with streaks and stripes the rose can revert back. How pronounced were the 'flecks' on the rose you grew?
I wouldn't place too much importance to the number of 17-25 petals. MR says "double". This can mean anything from double to very full, unless the number of petals is specifically mentioned. When reflecting "double" in HMF, the standard is 17-25 petals. Possibly this rose is "full". In many cases we have to revise the double designation to a more specific very double, full or very full, when there is additional information on the number of petals.
