'Shonosuke-Bara' rose Reviews & Comments
HelpMeFind's future is in your hands - Please do not take this unique resource for granted.
Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.
We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.
Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..
We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.
As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

Some of the references say this is a small bush and one says it needs a bit of pampering.. In Western Australia this grows with long canes and today the bush is about five and a half feet high and the canes are probably about six feet in length. I know I have pruned it back twice since I planted it in 1997. It has only ever had rainfall but I have thrown a bit of blood and bone at it some years. I have never seen it affecting any nearby roses with virus or distorted leaves.

I also have hips forming on 'Bullseye' this season using 'Watsoniana's pollen. No symptoms on the seed parent.

I recall reading that this form is suspected of being the result of a viral infection. If anyone has any information or references that confirms or denies this suspicion, I would appreciate hearing from you.

Hi Cass
In my opinion this phenotype is probably just virus induced. Tens of years ago I saw this distortion along a row of a botanical collection at Frejus, french Riviera. Clearly starting from watsoniana, up and down the row all plants were with very narrow distorted foliage, often much more than watsoniana. I remember laevigata had very distorted narrow quite freaky foliage.. All collection was burnt. Proving virus induction shouldn't be so difficult. Contamination was from insects, nematodes or more likely from pruning tools. Root grafts are less likely as these plants origin were diverse?

Journal de la Société Nazionale d'Horticulture de France 1896. Pag. 489-490.
2° Par M. Maurice de Vilmorin, un rameau de Rosa Watsoniana Crépin, espèce qui a été décrite et figurée dans le Journal Garden and Forest, en 1890, vol. IV, p. 477, fig. 59. Cet arbrisseau, dit le présentateur, a été importé il y a une dizaine d'années du Japon, son pays d'origine, à Albany (Etat de New-York), d'où il se répandit dans les collections américaines. On l'avait d'abord rattaché au Rosa muliflora; mais, M, Crépin qui s'est attaché spécialement à l'étude des Roses, la classa comme espèce distinte près du R. anemonaeflora. Quoique très rustique et fleurissant abondamment, elle ne produit pas de graines, ce qui peut faire supposer que c'est une forme anormale depuis longtemps cultivée, ce qui est d'autant plus probable qu'on ne l'a jamais rencontrée à l'état spontané. Le Rosa Watsoniana est une plante à rameaux grêles, demicouchés ; il est d'un très grand intérêt comme curiosité scientifique, mais n'a qu'une faible valeur au point de vue horticole. Les fleurs, d'un rose pâle, sont réunies en nombre considérable en inflorescences pyramidales ; elles sont très odorantes, mais de dimensions si réduites qu'elles mesurent à peine 1 centimètre et demi de diamètre. La plante est plutôt intéressante par son feuillage constitué par des folioles espacées, longues, très étroites et divergentes. Des remerciements sont adressés à M. Maurice de Vilmorin.

Wonderful, we have added this reference to HMF. Would you be interested in adding other plant references directly - we would appreciate the help.

If you let me know how to do, I will certainly be happy to contribute the references I found!
