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.

This cultivar has a very high vitamin C content, 1200 mg/ 100 g fruit flesh, and has been grown mainly in Germany together with genotypes of R. villosa subsp. pomifera cv. 'Karpatia' from Slovakia (Albrecht, 1993).

Pillnizter Vitamin Rose 'Pi-Ro 3': Not all roses have the same high level vitamin C content. also, a high quantity of usable fruit flesh does not necessarily correlate with a large vitamin content. Therefore, in places such as Russia and the former East Germany, people have for many years sought strenuously to select forms of vitamin roses that combine the two factors, quantity and quality. They have found the group of Pillnizter vitamin roses, from which the selection 'Pi-Ro 3' comes very close to the desired ideal. In free-growing, decorative hedges, this shrub rose, which is produced from the native variety Rosa pendulina, displays a lush burst of flowers in spring and an abundance of hips in the fall.
