Invasive rose, ID?

Did my app identify this right (see 3rd attachment)? First I thought, ok if this is a rose I'm for sure keeping it. Then I saw another rose variety mentioned on This Old House that looked just like it, they said it was invasive.... course I cannot remember the name they used, but some type of rose. Should I pull it? It's at the base of a black walnut.

    Why would this be any more likely to be some exotic foreign species rose rather than a dead common, everywhere to be found invasive one? There are enough similarities to them morphologically to mislead any plant ID app.

    In the first photo I think I see a bud and it's way too early for multiflora to be budded yet so it must be something else.

    I don't see any buds. But I do see some leaves that have not yet fully unfurled............

    I definitely see a flower bud :-)

    Can you point out where?

    It also doesn't look like a typical synstylae flower production.

    If you say so :-) I'd be hard pressed to call that a bud.

    7 leaflets, or 5, or both?

    Provision out of focus photos by the OP - unintentional?

    Rendering the whole thing more ambiguous than Rorschach inkblot #3

    Looks slightly like Chestnut Rose, Rosa Roxburghii. But that one has distinctive buds and hips. Could you come back and post some more (and clearer) pictures in a few weeks?

    From first glance neither the leaves nor hips look like mulfiflora. Would like a clear picture of the stumbled to check for Fri ging.

    Rosa multiflora has unique fringed stipules. I can't view any in the photos. Key charecter, leaves and hips aren't much help. Need a close-up of a stipule.

    well keep us posted ... as to flower color ...


    but in my experience.. VERY FEW things.. that shoot out of the butt of a bird .. pre-fertilized.. are of any value.. most are near invasive WEEDS that are in such volume in the area.. that the birds spread the seed everywhere ..


    as noted.. if you have the rare.. one in a billion exception.. get naked.. and do the happy dance to gaia.. mother earth.. that she blessed you with such good fortune...

    The wise thing to do is wait until you see flowers open. Even the most skilled rosarian can have difficulty identifying a rose by a few spring leaves alone.

    Im betting its R. multiflora, in which case you should remove it. But wait till it blooms, then report back here with photos, please.

    MR ususually has between 5 and 11 leaflets. It's thorns are curved unlike most other roses. I can't see any thorns or stipules in the photos. It is most often confused with Rosa rugosa and the polyantha roses which are hybrids created using Rosa multiflora. The pics are blurry, out of focus and the grid of 4 pics is hard to see, but there, in the grid, you can see that some of the compound leaves have 11 leaflets. The 'bud' is so blurry that it could easily be unfurled leaves. There are no thorns visible. We need a clearer pic to determine if it has thorns or not. I dont know how much help can be gleaned from the hips pic. I ran them through my app and it suggested the hips were mangosteens. The hips pic is taken too close, so you can't get a clear idea of the arrangment of the hips. In the identification literature the hips of multiflora are never mentioned as a method for IDing. Really a waste of time speculating any further until better photos are provided.


    Rosa multiflora.

    The like is for ” … shoot out of the …”, ken.

    stumbled to check for Fri ginggingShould read stipule to check for fringing.😃

    From what I see it doesn't seem to have many thorns, and the multifloras around here are very thorny... but my yellow (which just opened its first bloom today!) is also quite thorny so that's not much help.

  • 3 years ago

    I'll take some better photos later.

    I think its multirose, I have other singular vines just like it shooting out of the ground in random places, signaling invasive to me.

    I couldnt possibly be so lucky.

    Ive never seen it bloom once, couldve been because of the deer though...

    Many, if not most, roses sold are grafted onto a really boring rootstock, often multiflora rose. If the grafted part dies (quite common in neglected roses), you are left with a rose variety selected for its roots, not its flowers. Since the rootstock is chosen for its hardiness, if any shoots from the rootstock aren't pruned off, eventually, they overwhelm the grafted part and your lovely rose becomes whatever the rootstock was.


    So, the chances are good it's an invasive that was chosen for its roots, not its flowers and, in the shade of a black walnut, you're unlikely to get any flowers from a more attractive rose, so grafting a prettier variety on is not going to work.


    I'd pull it up. You can wait to see what the flowers are like, if you get any, but I would be very surprised if they were anything worth saving.

    I love to see what a surprise plant it. I would let it bloom.

    Ugh multiflora plagues me on my semi-wooded property. So tough and it will spread by seed and runners and bits and pieces so don't let it go to seed. You will have to kill it 100 times but if you are lucky you might be able to wrestle a few of them out of the ground and that is satisfying indeed, even if you get all scratched up. I don't know when mine typically buds up but I've been seeing the foliage all over the place for weeks here in 5b VT. I def wouldn't get hopes up based on one of those ID apps. TBH I have found Google image search to be far more reliable, but even though that gets better by the day it still is often flat out wrong.

    In the event you need to get rid of it (or for anyone who comes across this thread trying to get rid of multiflora): I am a devoted organic gardener but I do selectively use chemicals on a few really aggressive, woody invasives. This works on buckthorn and bittersweet (somewhat) as well. Cut that rose back and back and back all summer, disposing safely of cut canes (like not in your compost pile where it can re-root--I either burn mine or send to town yrad waste pile which is also burned) and then in the fall paint a fresh cut stump with an herbicide. At that point the plant is storing nutrients and the poison will be more effective. I use this ingenius little device called a buckthorn blaster to selectively apply herbicide to my invasives. Good luck getting rid of it.

    I don't know about your zone, but in California, there is a native rose that will slowly spread (I think my gophers chew up parts and re-plant them). Mine is in an area I don't water, so it doesn't really bloom much. I think mine needs a more moist environment. Every once in a while I forget it's there, and reach down to grab a weed and grab a thorny little new growth! Ouch!!!
