What is this plant?
I found this growing in our yard in full sun. What is it? Is it an invasive species that I should pull up and toss? Or is it worth transplanting and cultivating? If it’s worth saving, it is a perennial? What are the ideal growing conditions? Thanks!!
This looks like a rose shrub. Its growth habit suggests that it may be a domestic, not a wild (invasive) rose but you'll have to let it grow larger to be able to tell for sure.
As you may be aware, the non-native invasive rose--Rosa multiflora-- is a common pest and should be removed. You'll have to let this plant grow for a while to be able to distinguish whether it is a good rose or multiflora rose.
If it produces white flowers and does not grow in a compact shape, it's likely to be multiflora rose. If it is a "volunteer" plant, it most certainly is rosa multiflora and you can just remove it now.
