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.
Is 'Assiniboine' a Parkland series rose? It was hybridized by Henry Marshall (of the Research Station in Morden, Manitoba) in 1962 and introduced by Agriculture Canada at Morden. Does that make it a Parkland rose? Thanks for any light you can shed on this question.
RHA Newsletter 8(4): 13-14 (1977) Excerpt Canadian Rose Annual, 1976 BREEDING for WINTER HARDINESS and COLOR in ROSES H. H. Marshall Canada Department of Agriculture, Research Station, Morden Manitoba. The main reason R. arkansana has not been used more often as a parent is probably because of difficulty in obtaining the first cross. There are strong interspecific sterility barriers between R. arkansana and cultivated roses but a few Floribunda roses such as 'Donald Prior' will accept R. arkansana pollen. First generation hybrids are often moderately fertile and may be crossed to sister plants or back to either parent. ... 'Assiniboine' is first generation 'Donald Prior x R. arkansana (red form), It has been backcrossed to both parental types and also to several hybrid teas and numerous combinations of the resulting hybrids have been made.
The Canadian Rose Annual (1967) pp. 102-104 Progress in Hardy Everblooming Roses PERCY H. WRIGHT Saskatoon, Sask.
The prairie tetraploid species, suffulta, easier to blend with Hybrid Teas to produce fertile or partly fertile hybrids than rugosa just because it is a tetraploid, has recently been used in crosses with both Hybrid Teas and Floribundas, crosses which seem to be easy enough to achieve if suffulta is used as the pollen parent. One of the most interesting of the Suffulta Hybrids, Assiniboine, was originated when H. Marshall of the Brandon Experimental Farm put pollen of suffulta on the pistils of Donald Prior. Assiniboine is of very different character from the rugosa hybrids, and better in several important characters. It is, however, less hardy than Hansa. When moisture is sufficient, it re-blooms profusely in August, at least in the latitude of northern Saskatchewan. Since its male parent Donald Prior is only a semidouble, Assiniboine is semidouble too. This defect will almost certainly be remedied in future breeding.
Hello, I thought that I should let you know that Birch Creek Nursery no longer has a retail division. They have become only a wholesale business as of 2009. I was looking up the shrub rose 'Assiniboine', and this nusery came up as one of the mail order companies that carry this rose. Sorry. No longer. Just wanted to let you know. Sincerely,
