Weed of the Month – Virginia Copperleaf

Tomato plants are a staple in many gardens, but did you know that there are weeds out there that can easily be mistaken for them? From horse nettle to black nightshade, check out these Weeds that Look like Tomato Plants.

No other plant native to South Carolina has such fragrant and beautiful spring blooms and stunning fall color as the witch-alders. Fothergilla was named after Dr. John Fothergill, an English physician and gardener who funded the travels of John Bartram through the Carolinas in the 1700’s. These beautiful shrubs have been planted in both American and English gardens for over 200 years, including gardens of George Washington and Thomas Jefferson.

Virginia creeper is a native North American, deciduous vine, which can easily climb 30 feet or higher. Its tendrils end in oval shaped disks that adhere to surfaces and can damage stucco, the mortar between bricks, and painted surfaces. This highly adaptable plant grows in full sun to full shade. Grown as a groundcover, it can provide erosion control on slopes. Virginia creeper is very drought tolerant and a vigorous grower. To control the spread of this somewhat aggressive vine, prune, mow, or weed whack in the spring.

It’s late summer and crabgrass weeds have invaded some lawns. Unfortunately, crabgrass is very difficult to control with most herbicides once it develops a few tillers or branches. There are several species of crabgrass (Digitaria spp.): tropical crabgrass, smooth crabgrass, India crabgrass, large crabgrass, Southern crabgrass, and blanket crabgrass. All of them are summer annuals that germinate primarily in spring, grow during the summer, set seeds, and then die with the first frost.

Are you looking for an early-season, shade-loving perennial that has blue flowers and is also a native perennial wildflower? Then Virginia bluebells (Mertensia virginica) are an excellent choice to add to your landscape.

Smilax vines go by the common names greenbrier or catbrier due to the thorns covering their stems. There are 300 to 350 smilax species worldwide. Approximately twenty-four species are native to North America, with fifteen species growing in South Carolina. Smilax grows well in moist shade and is an important food source and habitat for wildlife, including birds, rabbits, and deer.

Cudweeds (Gamochaeta spp.) are herbs in the aster family that serve as host plants for American painted lady caterpillars. There are about fifty plus species, and all are native to the Americas. Most cudweeds are annuals and can be either winter or summer annuals. They flower in mid-spring to early summer or in early fall. Some cudweeds can be biennial, meaning that they will form a basal rosette that can survive the winter and flower in their second year.

This North American native plant is a relative of the popular holiday poinsettia. Both plants are members of the euphorbia family. This plant is sometimes grown for the colorful green and orange bracts, but it is considered a weed.

Lambsquarters (Chenopodium album) is a close relative of quinoa and is generally considered a famine food. It was once a popular green but lost favor after spinach was introduced to Europeans around the 16th century. Although the plant is dense in nutrients, it can be mildly toxic if eaten in often or large quantities. Luckily, cooking resolves this issue. It remains a pervasive weed in agriculture and is found throughout the United States. Lamb’s quarters can be found in waste areas, roadsides, home gardens, and landscape beds.

The spotted lanternfly (Lycorma delicatula) (SLF) is the latest non-native species to take hold in the U.S. This planthopper is large (about a half-inch long) and originally from several countries in the Far East. It was first found in Pennsylvania in 2014, and active infestations are now established in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, Ohio, West Virginia, Virginia, and as of just last week, North Carolina. SLF has not been detected in South Carolina, but it is an insect for which we need to be on the lookout.

Rustweed or juniper leaf is a native plant that earns its name from orange coloring in the fall. It is a drought-tolerant summer annual or short-lived perennial plant. It is found throughout the southeastern United States on mostly open, disturbed sites. Rustweed is considered a ruderal species, meaning that it colonizes open ground and does not handle competition well. Research has shown that rustweed seeds can remain viable in the soil for over one hundred years, just waiting for optimal conditions.

I must be selective in the kinds of shrubs and trees I add to my landscape. Very simply: I don’t have the room. Like the village matchmaker, Yente, in Fiddler on the Roof, I match the plant with my landscape, paying particular attention to sun exposure, drainage, and room to grow. I also consider its maintenance requirements, particularly water, fertilizer, pruning, and pests. As a tough-love gardener, I have no tolerance for needy, wimpy plants.
