Isn't it a rose?

Yes it is.

OP: Does it have Flowers in the summer.

I really can’t remember any. But these are the buds so far, I will keep you informed.

Those are rose buds. Could be the invasive R multiflora.

It doesn't look quite like multiflora to me. Something about the bud arrangement looks off for multiflora to me.

Take some pictures when it starts blooming. Make sure to include good photos of the canes and leaves.

I will do, see you when they bloom.

Yes. Multiflora was just a guess. It does seem a bit too tame for that one.

It feels like an OGR to me. Mad Gallica is the ideal rosarian to ID this ;)

OGR? Not plant savvy!

OGR= old garden rose (an acronym for antique rose). Mad Gallica has a lovely collection of hardy OGRs and generously shares her knowledge.

OK, can’t wait to see what the blossoms look like.

I got the “Picture This” app, and it shows this:

Multi flora

I wouldn’t trust any app over some of the rose people here (that does not include me. 😉) Post the flowers and you’ll get an answer.

OK, was just saying what the app said, it said my crab apple tree and my neighbour’s apple tree was a paradise apple, so???

These are the flowers.

A close-up.

Looks like a multiflora.

Please hold a coin next to a bloom for size - is an individual flower the size of a dime, nickel or quarter?

Multiflora rose or Wild Blackberry.

No, the foliage is rose. I'm wondering if it might be alba semi plena.

Yes, it’s well established that this is a rose. The only question is which one?

I wish the OP would post photos of the bloom, foliage (including stipule) and whole bush on the Roses forum for ID so Paul Barden and Mad Gallica will be sure to see it.

Inches and cm for those across the pond from each other.

Okay, I can see fringed stipules and the bloom size is appropriate for multiflora but I don't get why the previous homeowner would plant that and prune it as a landscape shrub. Perhaps it was rootstock from a grafted hybrid tea. Thank you for providing so many photos, Connie, you've been a great sport.

I am not well versed in plants/botany, so are you saying that this is a weed?

Multiflora rose was imported from Japan a century ago to use as a natural hedging material for livestock. It spread widely across the US because birds eat the hips and poop out the seeds in random locations. It has formed thickets in the wild where it crowds out native species. Therefore it's classified as invasive across the US.

If you choose to keep it as an ornamental plant, it has wicked thorns and a rampant growth habit - it will need frequent trimming to avoid a "bad hair day" appearance. Plus it only blooms once a year. I would remove it.

This looks like an older home, and I would guess that over the years at some point this rose seeded in and was just left to grow. The fragrance probably fills the yard when it's in bloom.

Hi Cecily 7A - Thanks for the “history lesson”, It grows crazily, like I said before, I prune it back regularly thoughout summer, so it’s not a problem. This one does not have thorns though. Thanks for the thanks earlier.

Katob - I can’t remember if it smells, I currently have a bad bout of hayfever. I do think it seeded, because I don’t think the gardener who looked after the garden before we purchased it would have bought it.

No thorns ? That certainly doesn't sound like multiflora roses, they have thorns everywhere.

Yes, I am in the Maritimes.

I guess I was a bit confused when Cecily 7A said I should get rid of it, because apart from growing like crazy in the summer, it has not spread anywhere, or rooted in other places and I have 1/3 acre of land, and a barren area behind our land. So, I guess with the 5b hardiness zone, it seems non-invasive.

Thanks Mad-Gallica, (My plant bloomed just a few days ago) this plant is very Hardy and quite disease and drought resistant. I have never watered or given it and fertiliser, and it’s still doing okay, I guess.

If you prune your multiflora after it flowers and snip off the old faded blooms, it can't form hips and won't seed around. Since you like it, just deadhead the spent blooms and enjoy it in good conscience.

Cecily 7A - This plant does not spread here in the Maritimes, we went to -38 this last winter, only the hardiest of plants spread here. Invasive species possibly where you live, are annuals here and can be bought in garden centres.

I would double check the invasiveness of R multiflora in your part of Canada. Some sources say it is invasive all over. That said, it is widely grown in the British Isles and, although occasionally escaping gardens, it is not invasive here.
