I inherited a Gymnocarpa (Little Woods Rose) with my property. Do you know the best way to get rid of it. It's a real beast!
Yes, I could see where this rose could be a problem in more fertile ground. It appears to sucker off it's own roots when given the right conditions. I noticed it didn't seem to grow much above 4,000 ft.
Unlike most other wild roses it doesn't necessarily do well on more fertile ground. Most other wild roses do also sucker, some patches in Whatcom County for instance are quite large. The more typically behaved and vigorous species like RR. nutkana, pisocarpa are the ones that may have produced single clones covering fair patches of ground here, thorny thickets impossible to negotiate.
