Rosa Virginiana (Virginia Rose)
Also known as Rosa Virginiana, this species is common on the East Coast of the United States, but can go as far west as Arkansas and as far north as Quebec and Ontario.
It is a perennial shrub, much like the multiflora and swamp species. Left unchecked, it can reach six feet high in areas. It will grow quickly and can be borderline invasive on other vegetation. Its commonly found in the wild in meadows and clearings.
As with all wild species, flowers have five petals. They are usually pinkish in color with some yellow in the center. It can be recognized by its hairy stems and nasty curving thorns. Watch out when handling it. It blooms a little later than other native roses from early summer (June) to late summer (August)
