Old Field Cinquefoil

Yellow flowers with five petals. The leaves are palmately divided (like fingers on a hand) into 5 leaflets. The largest leaflet is sharply toothed for more than half of its length. (Compare to running five-fingers, Potentilla canadensis, where the largest leaflet is toothed for less than half of its length.)

Ox-eye Daisy

White ray petals with flattened yellow center disk flowers. Each stem has a single flower.

Periwinkle

Solitary purple flowers with a pinwheel shape. There is a white mark at the base of each petal.

Philadelphia Fleabane

One hundred or more white (sometimes pink or lavender) threadlike petals surrounding a yellow center. The leaves and stem are shaggy-hairy. The leaves are oval and clasp the stem.

Plantain Pussytoes

The flowers are fluffy white clusters at the end of the stem. The basal leaves are gray-green on the top and white on the bottom, very hairy.

Prickly Sow-thistle

Yellow, dandelion-like flowers with an urn-shaped base. The spiny leaves wrap around the stem.
