Bull Thistle - is a biennial. It grows over the summer months. The leaves are alternate; blades are simple and form in a rosette. The leaves are unlobed to pinnately lobed. The bladetip is pointed and the margins are toothed with spines. The root is a fleshly taproot the first year and a fibrous root system forms the second year. The second year of growth, thistle stems elongate. The elongated stems have alternating leaves. Flowers are present from June through October on the elongated stems. The disk flowers are dark pink to purple with spined bracts. Bull thistle spreads by seeds.

Burclover - is a perennial which is very similar in appearance to black medic. It contains a three oblong leaflets, the center leaflet being on its own pediole. The leaflets often have brown spots on the upper surface. The flowers of burclover are yellow. Burclover reproduces by seeds from "burred" seed pods as well as spreading prostrate stolons which allows bur clover to tolerate close mowing.

Lawn Burweed - (spurweed) is a low growing winter annual which forms mats due to branching. The leaves are opposite and divided into narrow segments or lobes. The flowers are small and inconspicuous. The fruit forms in the leaf axils with sharp spines. Lawn burweed reproduces by seed.

Virginia Buttonweed - is a prostrate-growing perennial with branching hairy stems. The leaves are elongated, lance-shaped and grow opposite one another on the stems and are joined by a membrane. Virginia buttonweed prefers moist, wet conditions. The tubular flowers of Virginia buttonweed are white to purplish, and grow in the leaf axis along the stem. Flowers resemble four-pointed stars. Virginia buttonweed spreads by seed and plant segments.

Wild Geranium - also called Carolina geranium, is a semi-erect winter annual. The erect stems are branching and covered with hair. The alternate leaves are on long petioles and are divided into segmented leaflets which are blunt toothed. The flowers have 5 white to pink petals and form in clusters. The seed forms in a fruit capsule that forms a "storks bill".

Carpetweed - is a summer annual with smooth prostrate branching stems forming circular mats. The leaves are light green in color, lanceolate in shape, being widest in the middle of the leaf and narrow at the tip and base. The leaves form in whorls containing 3 - 8 leaves. The flowers are white, contain five petals, and form clusters of two to five flowers. The clusters of flowers are formed in leaf axils. Carpetweed spreads by seed.

Wild Carrot - or Queen Anne's Lace, is a biennial. During the first year, lacy fern like leaves develop in a basal rosette form. The leaves are compound with multiple leaflets. Wild carrot has a slender woody taproot. The flowers of wild carrot are small and white. The center flower in the clusters is first to bloom and is usually purple. The flower forms in flat umbrella shaped clusters, 3-6 inches in diameter, called umbels. The hollow flower stalks develop in the second year, and stand 2-4 feet high. Wild carrot reproduces by seed.

Chamber Bitter - is a warm season annual. The stems of Chamber Bitter are upright and grooved. The leaves are small and have smooth margins which are arranged oppositely on branchlets. Flowers are inconspicuous and form in warm weather. The fruit of Chamber Bitter is green and form on the underside of the branchlets. The seed explodes and spread seeds in the surrounding area. Chamber Bitter reproduces from seed.

Chicory - is a summer perennial that develops from a basal rosette. chicory looks similar to dandelion in the rosette form, but the lobes of the leaves are not opposite like those of dandelion. The lobes of dandelion also point toward the base. The flowers of chicory range from bright blue to purple in color. The flowers form on stems that range up to three feet in height. The flowers form from June to October. chicory reproduces by seed.

Common Chickweed - is a shallow fibrous rooted winter annual which grows in moist shaded areas. The leaves are small, smooth, pointed at the tip and elliptic in shape. They are opposite on branching creeping stems, which root at the nodes. Chickweed adapts well to different mowing heights. The flowers of common chickweed are white small star like with 5 notched petals. Common chickweed spreads by seed.
