Rose Family This type of cinquefoil is branched and has three leaflets instead of the five that the others have (shouldn't it be called "Trefoil"!?). Norvegica means "Norwegian", so it seems this plant should be a non-native, however, it is native. I found this one blooming at the Haw Ridge Parking area in Oak Ridge in late May. Perennial Where seen:Oak Ridge, Great Smoky Mountains NP, Warriors' Path SP, widespread
Entire fields and waste places can be overgrown with these plants in the early spring. They are pretty, but like other non-natives, they can take over.
Mustard Family April 7, 2005 The "Cress" plants are in the same family as mustard, cabbage, broccoli, and radishes. They are considered "cruciferous," meaning they have 4 petals arranged like a cross. Rapeseed oil can be made from the seeds of this plant. I found these flowers blooming along the road in Claxton, TN, just down the road from Oak Ridge. Plants in the Brassica species are harmful to cattle, pigs and sheep if eaten. Winter Annual Where seen:Oak Ridge, Great Smoky Mountains NP, widespread {Formerly known as: Brassica campestris}
