could this wild rose be Rosa adenocarpa Greene?
It was found growing on a hill side in Douglas county Oregon, along cow creek after a forest fire.
it has 8 or 9 petals unlike the ground rose that has 5 petals.

The rose is not R. spithamea (you had asked me a few days ago in a personal email) of which "adenocarpa" may be a form, but R. adenocarpa Green is an unresolved name (so far not accepted). Either way, the flowers are too large, the leaves are very unlike, the growth habit appears unlike spithemea, etc.

It seems to be a semi-double; if so, it may be a bee or wind hybridized rose with R. nutkana as one parent. I suggest this because of the petal color, the sharp serrations of the leaves, and the round receptacle. (R. nutkana is common in the countryside of Oregon.) The receptacle in the photo shows glands or setae, but those of R. nutkana are smooth.

On the other hand, much of your photos remind me of R. x kochiana (the bud, the flower, the receptacle) except for the leaves, which on R. x kochiana are rather shiny.

Thank you for the reply. It is a strange rose.
I went looking for the rose last week in the same place that one was growing but found nothing. it is like they came up after the fire, bloomed and then died.
I will look for them again in the spring.

Re: R. spithamea
The reason the two statements on prickles seem contradictory is that both are only partly correct. Some branches have no or very few prickles. Others many straight prickles. My observation (this rose grows among rocks in the hills outside my town, and comes back every year without fires) is that the lower and older branches of this ground hugging rose rarely exhibit prickles, while the smaller, newer branches (twigs, actually) are usually quite full of straight prickles.

I found this rose growing here in Douglas County Oregon after a fire. I am thinking it is Rosa Spithamea. however it is curious as there are around eight or nine petals on the bloom, and the plant had sparse thorns or none at all.

This-one looks like a (semi-)double, in contrary to other photo's and the description.
Very nice foliage... and no prickles to be seen.
Did the plant have prickles?
I'm not acquainted with this rose and am NOT questioning if it is correct or accurate.
Just curious!

The rose in Question had about 8 petals and I do not remember any was found growing after a forest fire in really rocky, shale, soil. the only rose that it could be is the ground rose. I believe it only grows in California and Oregon.
there is a nursery in France that may have this rose for sale.

It would be interesting to grow this rose, pruned and fed with potash.

It may be a little hard to grow because they come up after a forest fire.

Looking great and healthy! Eager to grow as it seems?

on the most part healthy. it gets black spot here in Oregon when the rain begins. otherwise a great plant, wonderful scent and color.

As for the Black-spot, that might change once settled (out of the pot) in the ground.
