'Mountain Rose' Description
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.

Notes:
Rosa woodsii var. ultramontana (S. Watson) Jeps. (1936)
R. woodsii subsp. ultramontana is native from central British Columbia east to Idaho, western Wyoming and south to California east of the Cascade Mountains, Utah and Nevada. It is the most common rose in the Great Basin of Western North America. See References.

Other subspecies of Rosa woodsii are: R. woodsii subsp. arizonica, R. woodsii subsp. manca, R. woodsii subsp. gratissima and R. woodsii subsp. glabrata. See References for a 2007 article by Walter Lewis and Barbara Ertter.

This rose is noted especially for its hips, which are said to make an outstanding tea. The hips are exceptionally fragrant, especially after a frost or two. Individual flowers last only one day, but each cane can bear several dozen, so there is a long period (about a month) when there will be an enormous amount of flowers. (Contributed by F.
