it does sort of look like it's in the rose family. I've seen roses before that aren't the full, multi layer of rose petals like we normally see, but more like this where they sort of flatten out when in full bloom. does it have thorns on the stems like a rose would?
you say it flowers in clusters, how many flowers to the cluster? I can't tell if the flower is small but it looks fairly big..the reason I am asking this is that I have a couple roses that a friend gave me, and they are not climbing, but they also have roses in clusters, 7 as a matter of fact, the rose itself is fairly small, and it is called "seven sisters" a very old heirloom rose.
they seems to usually grow in clusters of 5-7 and several of them, like the one pictured in the link above, have that flatter appearance w/o so many layers of rose petals. I know you said earlier that yours doesn't climb, but do you have it planted along something that could it could climb? Based on the various photos I saw of different climbing roses, that sure is what it looks like.
I believe I do remember seeing at least 5-7 growing in clusters. Unfortunately, the plant is done for the season so, I can't go out back and check how many. I have the plant against my iron patio. It does seem to be helping to hold the plant up.
BTW: I saw the picture that you provided Tammy. The flower size and shape looks a lot like the information you provided.
veggiewhisperer, I showed this to a friend of mine that really knows roses, she says this is a very old heirloom rose called "Dr.Huey'rose and was used for rootstock for hybrid tea roses. You have a nice rose!
