At the beginning of the week, I noticed our native magnolias flowering profusely. First, the evergreen southern magnolias (Magnolia grandiflora), which line the entrance to the South Carolina Botanical Garden (SCBG), put on a show. Then, a few days later, one of our deciduous magnolias, the bigleaf, was covered in plate-sized flowers. In fact, the bigleaf (Magnolia macrophylla) has the largest simple leaf and flower of any native plant on the continent. Magnolias are an ancient plant, one of the earliest flowering trees (angiosperm) in the world. I love to think about these trees growing among the dinosaurs in the Cretaceous period, around 100 million years.
Magnolias evolved before bees and are pollinated by beetles who forage in the flowers for pollen and nectar. Over time magnolias and beetles co-evolved. The female flower parts (carpels), leaves, and seed pods are toughened to withstand the onslaught of chomping beetle mouthparts. The carpels mimic the male flower parts (stamen) to encourage the beetles to stay longer and dine more. Female stigmas are active first, and they emit a strong fragrance to attract beetles searching for nectar. Later In the evening, the magnolia flower closes to trap pollen-covered beetles inside. In the morning, the trapped beetles are showered with fresh pollen that they move to the next blossom. Bees and other insects also visit but are not pollinators.
Our iconic, evergreen southern magnolia is widespread. Less well-known are the native deciduous magnolias, which make their homes in our woods. M. macrophylla (the bigleaf magnolia mentioned above) is native to our region but not common, so being able to see the specimens in the SCBG is a treat. Other native deciduous magnolias you will

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.
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.
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.
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.
Our South Carolina water resources help producers grow the crops we eat, supply drinking water when we turn on the tap, and support industry and our outdoor lifestyle. It is important to recognize how we use water in our community so that we can each do our part to help conserve this important resource. Do you know who is the biggest user of water in South Carolina? It may not be who you think.
The Asian longhorned beetle (ALB; Anoplophora glabripennis) is not easy to miss – adults of this large, black beetle with white spots, black and white striped antennae, and blueish feet are between 1 and 1 ½” long (Fig. 1). ALB larvae are equally striking as the large, white segmented larvae can be nearly 2” in length (Fig. 2). Established populations in the U.S. are found in Massachusetts, New York, and Ohio, and a new infestation was recently found in Charleston County, South Carolina.
Clemson University’s Cooperative Extension Service is proud to offer a brand new program to the citizens of South Carolina! Many landscape professionals, whether in the private industry, grounds-maintenance, or employed by government agencies, are in constant need of good training resources for themselves and their employees. Many homeowners also want to know that their landscape operators/providers have the skill set necessary to deliver consistent, high-quality service.
Copperhead snakes (Agkistrodon contortrix) are found throughout South Carolina and are one of the six venomous snake species, out of 38 total snake species, that our state has.
Rob Last reports, “Strawberry crops are developing well; however, we are seeing gray mold phomopsis blight in some crops. Sanitation can really help prevent botrytis from spreading as we move forward when allied to fungicide applications. Keep scouting for spider mites as there are active populations in some crops. Now is a great time of year to think about the maintenance of equipment for bed formation, cultivation for spring crops, and most important product application.”
Pyrus calleryana ‘Bradford’ was once touted as the perfect, sterile garden or landscape tree. It has now bred prolifically with other pear species and spread so extensively that it is now on South Carolina’s invasive plant list. Now is an excellent time to replace these pest trees with something more ecologically sound. We have several options to choose from at the South Carolina Plant Sale or visit your local nursery to find alternatives. The SCBG plant sale is online again this spring; details are here: https://www.clemson.edu/public/scbg/plant-sale/index.html
Native grasses are an excellent choice for low-maintenance, attractive, and wildlife-friendly plants to add to your landscape. Their beauty is often more subtle than the color splashes of perennials and annuals but can add amazing depth and interest to the gardener’s palette. There are so many species of native grasses to choose from, and each one brings differing structure, texture, and color to the garden. Grasses give multi-season interest to the landscape. Perennial grasses mostly emerge in the spring and are at their peak in summer and tend to be happiest in full sun. Persistent seed heads provide structure and movement to the garden in the fall and well into the winter.
The recent news that all Pyrus calleryana cultivars – the most common of which is the Bradford pear – and several Elaeagnus species have been added to the “do not sell” list in South Carolina has generated a lot of buzz and a lot of questions from homeowners. We’ll try to answer some of those questions in this blog post.
