'R. californica florepleno' 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:
See References for questions about this rose which is commonly dated to 1894, the date of Geschwind's 'Theano' and at least 16 years before Willmott published The Genus Rosa.. It is most probably identical to 'Theano', as there seems to be no trace of it in the wild. The rose pictured by Parsons in "The Genus Rosa" looks different however.

One of the Roses that "passed the test" in Longwood Garden's Ten-Year Rose Trials.
