five leaves, thorns, arcing stem (pic)
I hope one of you can identify this weed. I don't remember seeing it in this spot last year.
The plant is shrublike, with long arcing woody stems, about 5 to 6 feet tall. The leaflets are in groups of five, and the "flowers" are little balls of stars.
The stems have thorns which are more noticeable on the younger green stems. Older stems are woody looking.
Any ideas? I would love to know what this is before I decide whether or not to remove it.
