Florida pusley is a low-growing, annual weed species that appears almost prostrate. It can be effectively controlled only with pre-plant incorporated herbicides. Florida pusley has bright green leaves with a distinctive recessed mid-vein. The stems are very hairy and may have a purplish appearance. The flowers are white with six petals in a star-shaped whorl.
Common lambsquarter is a small seeded annual broad-leaf species particularly troublesome in the Virginia-Carolina region. It is an upright plant, which can exceed seven feet at maturity. Its arrowhead-shaped leaves grow alternately and often have a whitish dusty appearance on their undersides even in the seedling stage.
Small Flower Morningglory
Small flower morningglory is probably the most common morningglory species in the Southeast. The cotyledon stage resembles a wild radish seedling with heart-shaped cotyledons. As it grows, small flower morningglory will stand nearly erect until 12 to 18 inches tall, then it will begin to run. It has heart or spear-shaped leaves and produces small blue flowers in a cluster.
Tropical spiderwort is an annual species similar to common dayflower. It is distinguished from dayflower by the presence of subterranean (underground) flowers. Leaves are spoon-shaped with parallel venation and blue above-ground flowers. Stems are succulent, and the plant re-roots quickly after cultivation. It spreads by seeds. Spiderwort germinates throughout the season, hampering control efforts.
Similar to other morningglory species, tall morningglory has a vining, prostrate appearance that envelopes the peanut canopy. It has heart-shaped leaves with overlapping lobes at the base and slightly hairy stems.
Spurred anoda is a troublesome broadleaf member of the Mallow or Cotton family. Its alternate toothed leaves are two to four inches long and sometimes have purplish veins. It produces small, pale blue flowers and a unique fruit that looks like a fancy ribbed pie surrounded by a star.
Tropic croton is an upright, branching annual broadleaf with serrated leaves. Tropic croton has a rough hairy stem, but it is not as hairy as the related species, wooly croton. Its gray-brown seed are desired food for doves.
Red morningglory is a relatively common annual morningglory species, but often doesn’t appear until later in the season. The key identifying features are the distinct points on the leaf margin and relatively small red flowers.
