The grafted part - top - will usually be inferior in hardiness and other aspects to the rootstock so the top dies - the roots send up shoots and then you have a Multiflora rose ready to go! You can obtain roses on their own roots - hardy roses that is - but not at the local store! Enjoy the rain - it will help the roses.

See = versicolor.ca/multiflorarose <http://versicolor.ca/multiflorarose> =20 =20 We might keep in mind that about 1/3 of our flora is of exotic origin = at least in recent centuries, and mostl of these species are plants of = disturbed habitats, perhaps all (except (glossy buckthorn?) are not = shade tolerant; their introduction since European colonizations reflects = the greater abundance of ruderal species in Europe & Asia because of a = longer history of extensive human disturbance than in NA. On the whole = these immigrants perform important ecological functions and do not = seriously threaten native plant communities.

Perhaps where they do threaten = native plant communities in NS that is a transient process as it likely = was for many of the exotic species for a period after they first = arrived. =20 =20 NS is likely species depauperate because of the short time since the = glaciers retreated and our relative isolation as a peninsula on the = Atlantic coast, so in a sense we are "open for business" when it comes = to immigration of new plant species. I think we should be very actively = conducting Assisted Migration, particularly for forest species, to = increase species diversity and resilience in the face of climate change. = Anyway, a few thoughts for the mix. =20 =20 PS: I have spent some time cutting back multiflora rose near The Bluff = Trail trailhead, as it is still not abundant along the rails to trail = BLT, and so far there are no exotics once you get 5 m into the trail, so = it takes little effort at this point to keep it out. I do not have R = multiflora in my back yard but if I could obtain a non-invasive type, I = would welcome it both as an ornamental and as bird food.
