Don’t even think of getting any. I planted some that I got from our state as it was highly recommended for birds. At one time our state also recommended multi flora rose for quail...think they spent a few zillion with assistance to get rid of it.
It is a highly invasive species and extremely difficult to control. Now it is on the states noxious species list. From experience it not only will invade pasture, but I’m sure if given enough time take over pasture. Saw it off and it comes back twice as fast and bigger. Cut stump with chemicals is the only threat to it. Think I finally have it all killed out...but wouldn’t surprise me if I see one.
Again don’t even think of getting any.
Did a quick Google...read about it right here.
