 Rough-fruited
Cinquefoil
or
Sulfur Cinquefoil
Potentilla Recta
Classified as a
noxious weed in 5 states, see
USDA
What I suspect is a
Forest Service
site has the following information as well as a lot more information on this
"noxious weed."
GENERAL BOTANICAL
CHARACTERISTICS :
Sulfur cinquefoil is an introduced, perennial, long-lived forb with one
to several stems growing from a woody caudex. The erect, stout stems
are 12 to 28 inches (30-70 cm) tall. The leaves have five to seven
coarsely serrate oblong leaflets. The small seeds are slightly
flattened and 0.05 inch (0.12 cm) long. The taproot may exhibit some
lateral growth, but there are no rhizomes. Individual plants
approximately 25 to 30 years old have been found in Michigan, and
20-year-old plants are not unusual .
