THE BELOVED WILDFLOWERS of springtime—the trilliums, mayapples, Virginia bluebells—are probably gone till next year, but don’t despair. Here comes the next cast of players, the wildflowers of summer. The acclaimed naturalist Carol Gracie looks beyond their surface beauty in her new book on the subject, into their life histories and even cultural uses of plants like cardinal flower, lupine, milkweed, asters, goldenrods, and more.
Carol Gracie, a former longtime educator at the New York Botanical Garden who also worked for The Nature Conservancy, has followed her own intense curiosity to become a leading expert on wildflowers. Now her second book, “Summer Wildflowers of the Northeast: a Natural History” from Princeton University Press (Amazon affiliate link), forms the companion to her earlier spring volume.
We talked together about all the insects–not just monarchs–who use the milkweed plant in some way (and what they have in common); about a flowering plant with no chlorophyll at all; and even how experts have trouble keeping track of all the asters and goldenrods.

Margaret: So I want to start with the same question I asked you when we spoke, I don’t know, a few years back upon the publication of your book, “Spring Wildflowers of the Northeast.” The subhead on the cover of the new book, the summer book, as on the old one, says “A Natural History,” and I’d

“Passion is lifted from the earth itself by the muddy hands of the young; it travels along grass-stained sleeves to the heart. If we are going to save environmentalism and the environment, we must also save an endangered indicator species: the child in nature.” Richard Louv, Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder
Garden Sprouts is a program I run at the South Carolina Botanical Garden that is designed for preschoolers and caregivers. This class takes place once a week for three months every spring and fall. The goal is to share age-appropriate nature-based activities with children, who are mostly three to five years old, but sometimes younger or older. Over time I have learned the caregivers also learn things they never knew, enjoy the activities immensely, and are able to connect more deeply to the natural world through this program. The structure of this hour-long program is three-fold, we begin inside with a book related to the theme of the day, a walk or outdoor activity, and finally a craft. In this blog, I would like to share some of the books, outdoor activities, and crafts we have done in this class.
Want to add a tropical flair to your garden this spring? Elephant ears will add a bold statement to a filtered sun or high shade spot. These striking “drama queens” of the garden may be either in genera Colocasia or Alocasia. The easiest way to tell these beauties apart is that colocasias (Colocasia esculenta) will have leaves that point downward, and alocasia (Alocasia species) leaves will point upward. Depending on the species or cultivar of each genus, the size can range from 3 to 10 feet tall and 2 to 10 feet in width. Both types of elephant ears are native to the tropical regions of Southeastern Asia.
In springtime, the deciduous woodlands around us are beginning to awaken as the delicate flowers of spring ephemerals pierce the blanket of leaf litter. Most of these woodland plants are found in areas with rich, humusy soil and layer of deep leaf litter; they flower when the leaves are off the trees and light reaches the forest floor in spring. These diminutive plants are beautiful, but beyond this, they provide critical support for newly emerging spring bees. As temperatures warm, native solitary bees visit bloodroot, trout lily, spring beauty, Virginia bluebells, and other spring flowers to collect pollen or sip nectar. Some of these bees have a close or exclusive relationship with specific flowers, a fact recognized in their names: trout lily bee (Andrena erythronii) or the spring beauty bee(Andrena erigeniae). Trout lily bees visit more than just trout lily, but the latter relies exclusively on the pink pollen provided by spring beauty to provision their nests. However, many other bees visit this spring beauty too. In fact, 58 species of bees have been reported as visitors to this tiny pink flower. Similarly, bloodroot, trout lilies, and Virginia bluebells are visited by a diversity of bees, including bumblebees (Bombus spp.), little carpenter bees (Ceratina spp.), halictid bees (Halictus spp., Lasioglossum spp.), and mason bees (Osmia spp.). Clearly, these spring ephemerals are of considerable importance to the survival of many spring bee species, a fact we rarely consider when we admire their flowers.
Spring wildflowers are garden stars in the wooded area of South Carolina Botanical Garden’s Natural Heritage Trail from February to May. The spring herbaceous layer is exceptionally diverse in environments with rich soils containing lots of organic material. Every day something new appears in the landscape!
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.
As summer fades and fall’s cool temperatures and moist days arrive, this is a fantastic time for planting perennials, shrubs, and trees. Under these conditions, plants get time to establish roots without the stresses of summer heat and dryness. Luckily, this is also time for the South Carolina Botanical Garden’s semi-annual plant sale. As well as offering great quality plants of all kinds, plant sales are our major fundraiser. Through them, you support our operations and the enhancements made to this unique and free public garden. The catalog is available online for pre-sale planning Preview the Catalog (PDF). Garden staff, volunteers, and Clemson University students will be available at the sale to help with plant selection. In addition, several partner organizations set up booths at the sale to answer questions about gardening-related topics and activities. To find out who will be here this year, check the catalog. For additional information, please contact Misty Shealy, Nursery Manager, at [email protected].
This heirloom grain, together with the skilled knowledge and forced labor of West Africans and their descendants, made South Carolina very, very rich. From 1720 to the outbreak of the Civil War, rice was the most economically valuable crop for this state. White landowners, who thought rice would do well in the low country, themselves lacked practical knowledge of rice cultivation. Instead, they paid a premium to slave traders to capture and transport laborers from the well-established rice region of West Africa to Carolina. During the 18th century, many enslaved people brought into Charleston came from this rice-growing area. These people and their descendants created the Gullah-Geechee culture in the low country.
As a new year begins, educators at the South Carolina Botanical Garden at Clemson University are excited for a new season of classes and events for all ages. Our entire new calendar is here.
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.
Not long ago, we swapped pet peeves (like made-up plant names applied by marketers in the guise of trademarks) and also plants we’re crazy about—including overlooked ones, ones Tony calls “plants that need a good p.r. person.” He’d certainly be the publicist I’d hire if I were a shrinking violet with chlorophyll in my veins. Meet some of these overlooked creatures.Yes, Tony Avent allows the occasional common name—provided it’s a valid one, like catmint for Nepeta, for example, or elephant ear for Colocasia. But under the headline Peltoboykinia watanabei in his latest catalog, above the description including the Tony-isms “tall, bold and bodacious,” and a “fabulous member o
THE FIRST PERSON to photograph snowflakes did so in 1885, harnessing the combined power of a camera and also a microscope given to him as gifts by his parents. Then 20-year-old Alwyn Bentley of Jericho, Vermont, came to be known as the Snowflake Man for his lifetime of work, which also included years of close examination of raindrops. A fascinating tale of Bentley’s life, and more photos, via DomainReview [dot] org. Image above from the Smithsonian Institution collection. And yes: Bentley is responsible for the “no two are alike” lowdown on snowflakes.fresh as a frog’s skinA BIT OF RUSSIAN folk-wisdom that calls for keeping milk fresh by putting a live frog in the milk bucket has led to the examination of chemicals secreted from the frog’s skin. Apparently they are powerfully antifungal and antibacterial…but will they have implications for new drugs
