'Complicata' 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.

If the parentage is correct, wouldn't that make Complicata a (seemingly fertile) triploid, with A, C and D septets?

Has this rose been genetically tested?

There is an article "Rosa Complicata" in Curtis's Botanical Magazine, January 14, 2004, by Barbara Jellett, Maurice Jay and Olivier Raymond, which seems to include DNA test results. Unfortunately this article is not freely accessible.

Thanks Jedmar.
The RHS Encyclopedia of Roses says it was genetically tested and it is a canina hybrid.

I think that statement of RHS is too simplistic: If you look at the 2017 reference which is based on the Jellett et al article. 'Complicata' is closer to R. gallica than to R. canina. Unfortunately, I haven't seen the original article.

Thanks, yes I see. Suzanne Verrier says gallica x macrantha hybrid but canina and setigera have been suggested. It always reminds me a lot of Rosa canina.

Not a rose to cut for an evening function, because it closes up for the night.
