Gardenig in state South Carolina. Tips & Guides

Prairie dock (Silphium terebinthinaceum) lines the roadside edge of our Piedmont Prairie Exhibit at the South Carolina Botanical Garden. This plant is towering over the grasses and other prairie plants at about 10 feet tall. At this time of year, mid to late August, it is in full flower. The spray of yellow flowerheads at the head of the bare, tall stems is stunning against the blue summer sky. Each composite flower is about 2 – 2 ½ inches across, and each plant will flower for about a month. Today, when I left work, the flowers were covered in eastern swallowtail butterflies dancing in the breeze. Other pollinators are also attracted to the blooms, which are held high above the competing vegetation. Long-tongued bees, many small bees, hoverflies, and hummingbirds are all regular visitors. Goldfinches and probably other small birds and mammals are attracted to the seeds.

Latin scientific names can be challenging to pronounce but are tremendously important. We can communicate without ambiguity because each plant has only one scientific name. In contrast, a plant may have more than one common name, and common names may vary by region. Although easier to pronounce, using common names can result in a great deal of confusion and even frustration.

The elm zigzag sawfly (Aproceros leucopoda, SLF) is one of the latest non-native species to take hold in the U.S. It was first found in Virginia in 2021, and active infestations are now established in Maryland, New York, North Carolina, and Pennsylvania. EZS has not been detected in South Carolina, but it is an insect for which we need to be on the lookout.

North Carolina State Extension wrote an excellent publication on terrestrial flatworms, with common species around yards and gardens in the Carolinas called land planarians or hammerhead worms: https://content.ces.ncsu.edu/terrestrial-flatwormshammerhead-worms.

As the year passes, and as each new season settles upon us, we are blessed with abundant and various seasonal crops and produce. While in most mainstream grocery stores, we can now find our favorite foods all year round; however, many prefer to eat what is being grown specifically in that season. Here in South Carolina, entities such as Certified SC Grown is just one example of an organization that is working to bridge the gap between field and plate, making finding local, seasonal fruits and vegetables more attainable.

Everyone loves falafel—it’s a year-round staple, and the frozen options at Trader Joe’s make it incredibly easy to prepare. But today, you should probably rid your freezer shelves of any Trader Joe’s falafel: In the company’s third food recall this week, on July 28 Trader Joe’s recalled its fan-favorite Fully Cooked Falafel after being informed by the supplier that rocks were found in the food.

The row on the left has succumbed to bacterial wilt. In the row on the right are grafted plants that had bacterial wilt resistance.

December is the month we celebrate Arbor Day. So, consider planting a tree in honor of this day. Start by selecting the right plant for the site. First, analyze the chosen site by checking the soil drainage, number of sunlight hours, and amount of available space for a tree to reach its mature height and width. Once these factors are determined a tree species can be selected. CAUTION: Call 811, two to three working days before you dig. This service will mark underground utility lines.

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.

Convincing children to eat their veggies may sound like an impossible task, but a research study conducted by Parmer, et al. found that “second graders who participated in school gardening as part of a nutrition education class increased their selection and consumption of vegetables at school, compared to second graders who did not participate in gardening”.[1]

I recently had a call from a South Carolina resident who lost power for more than 24 hours and wanted to know whether the foods in her freezer would be safe to eat. This is a very common problem in South Carolina winters and could easily affect you in the coming months.

Japanese camellias (Camellia japonica) are one of the most recognized evergreen shrubs planted in Southern gardens. As the common name implies, these beauties are native to the Orient. The first ones were introduced to South Carolina by a Frenchman, André Michaux, who was a botanist to King Louis XVI. Michaux developed the first botanical garden in the South near Charleston in 1786. He shared his camellias with his neighbor, Henry Middleton, who started his landscaped gardens at Middleton Place in 1741. One of the original plants survives at Middleton today, a beautiful double red camellia ‘Reine des Fleurs’ (Queen of Flowers).

Slender deutzia (Deuzia gracilis) is a fantastic, but underused deciduous shrub for the sunny to partly sunny landscape. There are several cultivars of Deutzia available, and most produce a profusion of pure white, fragrant flowers during late April and early May. Deutzia will grow well in USDA Zones 5 to 8, which covers most all of South Carolina. In the warmer parts of the state, they will perform best with partial shade.

Pretty yellow flowers? Check. Great for the landscape? No check! The fig buttercup, also known as the lesser celandine or pilewort, is a non-native plant from Europe and Northern Africa that has the potential to become a very bad invasive species in South Carolina. This spring ephemeral grows and blooms early in the spring, which helps it get established in natural areas and gives it a competitive advantage over native plants. It can grow in incredibly thick patches, take over entire areas, and crowd out native spring ephemerals (Fig. 1). The leaves (Fig. 2) and flowers (Fig. 3) are toxic if eaten, and may cause vomiting, nausea, or dizziness. The roots consist of thick tubers and bulblets, each of which can produce a new plant (Fig. 4). These underground structures can help the plant withstand periods of drought or poor growing conditions and they are also spread when soil is disturbed.

Take a walk and enjoy the beautiful South Carolina spring.

A few years ago a friend, who was a native Alaskan, gave us a seed packet of alpine forget-me-nots (Myosotis alpestris) that she purchased on a visit back to her home state. We really didn’t think that a plant that flourishes in such a northerly region of the US would tolerate the heat and drought of South Carolina. However, we were pleasantly surprised!

Lenten rose is one of the first perennials to flower each new gardening year. The plant’s name comes from its typical spring bloom time in northern climates that coincides with the religious season of Lent. However, in South Carolina, Lenten rose may bloom earlier, often starting in late January. Lenten rose is the common name for hundreds of hybrid crosses of Helleborus species and their cultivars. The flowers of these species start pink, magenta, or white, and then gradually fade to light green. The flowers remain on the plant for several months.

What’s blooming at the South Carolina Botanical Garden this week!

Poke bowls, fish salads, originated in Hawaii and then became popular in California. The popularity of this dish has spread across the United States in 2018 and into 2019. According to Eater.com, the number of Hawaiian restaurants has doubled in the past two years. Poke bowls can be a healthy meal, and they offer a lot of diversity in one dish. So, it is easy to see why they are so popular.

Tired of planting the same old marigolds, petunias, and begonias? Try some different annuals in your garden this year. Many provide pollen and nectar for pollinating insects and attract hummingbirds. Here are a few of my favorites that I always incorporate into my landscape. They will perform well in South Carolina’s hot, humid summers, and with proper care, these annuals will continually bloom until frost.

Do you have a favorite insect? One of mine is a praying mantid. All mantids are excellent hunters and get their name from their prayer-like hunting pose. They sit and wait for their meal to get within striking distance and grab the prey by the neck. Even though mantids are considered beneficial predatory insects, they are generalist predators, meaning they can be indiscriminate when it comes to prey and are known to eat butterflies, bees, frogs, and hummingbirds. Sometimes, the male is eaten by the female during or after the mating process.

Florida pusley is a low-branching, annual summer weed. Its pretty, white, star-shaped flowers produce an abundance of seeds, and a single plant can quickly turn into an infestation. This weed is extremely drought tolerant and can easily out compete lawns that are not irrigated during extended dry weather conditions.

Summer at the South Carolina Botanical Garden (SCBG) that is a fun time filled with summer camps and children laughing and learning. Below are some of the simple, low cost ideas we used in our Creativity Camp to get children outside, where they enjoyed nature, and tapped into their creativity.

Want to brighten up a shady spot in your summer annual containers? Caladiums are an excellent choice. Due to their insignificant flowers, caladiums are grown for their colorful foliage. The leaf colors range in a wide variety of red, pink, white, and green combinations with contrasting leaf margins.

The Upstate is one of the few places in South Carolina with the right climate and soil conditions to grow productive apples trees. While the actual trees can be grown in most any part of the state, higher temperatures and humidity in the midlands and coastal plains make disease pressure hard to manage.

Have you ever seen a century plant bloom? If not, put it on your horticultural bucket list! Century plant is a common name for a number of species of agave (Agave sp.), usually Agave americana in South Carolina. Most agaves are monocarpic, meaning that an individual plant only flowers once in its life and then dies. In fact, the name “century plant” is a much-exaggerated reference to the long time it takes for the plant to flower. In SC, agaves generally require 10 to 15 years to grow large enough to bloom.

Late summer and fall perennial flower selections for South Carolina gardens.

One of my favorite August gardening joys is sowing crimson red clover (Trifolium incarnatum) seeds up and down my driveway. I look forward to the bright crimson red flower show in the spring.

The study of native plants, the ecosystems of South Carolina, and sustainable landscaping practices form the focus of the South Carolina Native Plant Certificate Program. A partnership between the South Carolina Native Plant Society and the South Carolina Botanical Garden, this program gives participants insight into South Carolina’s rich and complex botanical heritage, and offers ways to bolster the states’ biodiversity. This program began in July 2015, and to-date over 300 participants from all over the state, from all walks of life, and of all different ages, have enrolled in the program.

Are you looking for a medium-sized, landscape shade tree that will have amazing fall color of fiery yellows, oranges, and reds? Then, the Chinese pistache (Pistacia chinensis) is an excellent choice, and these trees are suitable for planting throughout South Carolina.

Any day now, temperatures should drop, and we will begin what I believe to be the best season in South Carolina – the Fall! This is not just a football-induced admiration. Fall is a great time to be outdoors and on the water. It’s also our best season to appreciate the culinary treasures of our estuaries – shrimp and oysters!

Ten species of hemlock tree exist worldwide, with four of those species native to North America (NA). The eastern United States is home to two of the native NA species, Canadian or eastern hemlock (Tsuga canadensis) and Carolina hemlock (Tsuga caroliniana).

Large patch disease is probably the most common and damaging disease of warm season turfgrass in South Carolina. The most susceptible turfgrass to large patch is centipedegrass, followed by St. Augustinegrass and zoysiagrass. Bermudagrass lawns are not as severely affected because with proper care, this turfgrass can outgrow the disease problem. The pathogen causing large patch (Rhizoctonia spp.) is more active in the soil during the fall after temperatures have dropped from the summer‘s heat and again in the spring as turfgrasses green up.

Mistletoe is often found hanging in American homes as a traditional decoration during the holiday season. Once believed to have magical powers, as well as medicinal properties, the custom in which kissing under the mistletoe would inevitably lead to marriage developed in England. Thankfully, our modern American interpretation of this tradition between partners, families, and friends is much more innocent. Most mistletoes are evergreen, making them easy to locate and harvest after leaves of their deciduous hosts drop in late fall and winter. Their visibility during this time is likely why the plants often are used as festive decorations at Christmas time.
