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.

How easy is the r. acicularis to grow from seed?
Reply #1 posted 25 AUG 16 by Wilhelm
Well, I have grown it from seeds collected in Mongolia. The seeds may take two winters before they germinate. It does well and has nice flowers even in a much warmer climate in Germany. In Mongolia it hardly grows over a foot high. And my German plants are not much higher. Thus I am not sure if the Mongolian/Siberian rosa acicularis is really the same as the American variety. There is also some confusion with rosa davurica. I am in Mongolia frequently and today I have checked again the pine-larch-birch forests at 2000-2500m altitude.Plenty of rosa acicularis here. Nice colouring of the leaves and nice hips. Morning temperatures at the moment around freezing, though today was exceptionally cold. Seems to grow everywhere in undergrowth under the pine trees. Doesn't like so much dry meadows. Pressure from other shrubs or trees does no harm. In winter temperature drops to minus 40 degrees Celsius and below regularly.
