All of my roses have been growing like crazy now that it has finally stopped raining and warmed up. One is growing out of control in the middle of the rose bed. I had thought it was all Vineyard Song. It has a similar form and clustered blooms.Both started blooming today, so I know which is which.

I have one single rose - Heiderlosein - a pink/white single which I planted in a different location. heiderlosen hasn't bloomed yet, but it had a few blooms last year. The appeared singly, had pink edges and were larger. Heiderlosen hasn't bloomed yet this season.

Here is a mediocre picture of the mystery rose.

I didn't take a closeup, but I will take more pictures with a different camera tomorrow.

I think I solved the mystery. While walking Winston the pug, I snipped some branches from the wild white roses growing nearby. I think a bird planted one in my rose garden. They have the same form, same blooms, same leaves. I'll have to get some pictures of them tomorrow also. These things can get monstrously big. In winter, it is hard to distinguish them from the blackberries. They have the same sprawling, thorny form, but different colored bard and different thorns.

I am off to search species and alba roses on helpmefind.

The blooms are white with yellow centers, born in clusters. Each flower is smaller than a dime. Each one has 5 petals.

Here are links to some pretenders on helpmefind. I am sure this is a native plant or a non native that has become naturalized. I like the advanced search option on hmf.....

R, laxa, the semi rose
http://www.helpmefind.com/rose...
The found rose has light green to green foilage, not grey green as per above.

Rosa spinosissima var. altaica
http://www.helpmefind.com/rose...
Similar foliage, but the found rose has much smaller flowers


The blackberry rose, R. Rubus

The best candidate so far, but listed as "not hardy" and "requiring spring freeze protection. This rose is naturalized here, growing in the wild with no care or protection whatsoever.

"The plant suckers WILDLY, helping itself to all the acreage available" - Oh, No Lagerfeld doesn't stand a chance against Olga F.! This one was originally found growing in mountainous regions of Turkey and Russia.

Himalayan Musk Rose, Mrs. Brown's rose, Rosa moschata var. nepalensis Lindl., R. brunonii

Experts seem to be debating the hardiness of this one. Some pictures resemble it, but my specimin has smaller flowers - I think there are others as confused as I am.

Muscadelle

It looks a lot like this Belgian-bred rose. It may be an ancestor, but the lineage wasn't listed on the site.

Dog rose, Briar Rose, Rosa canina L., Rosa sylvestris and others

Could be a white flowered version. Even the buds are white - no hint of pink at all. The found rose has more blooms per cluster and smaller blooms than most pictures. Like the comments, this one is easily spread by birds.

It could just be Rosa Multiflora, which is hardy to zone 4. I have one in my garden that looks just like that. It's a once bloomer and runs rampant in a dark and shady corner of the garden. One part of it is climbing up a black walnut tree.

Have you bought any roses from Canadian nurseries? They use it as the rootstock for grafted roses.

I'm enjoying your research. I think I need a couple of your "candidates".
