SUMMARY:AHS LIVE: The African Ancestors Garden
DESCRIPTION:Paul Peters\, principal at Hood Design Studio\, will share about the studio’s landscape design process for the African Ancestors Garden\, part of the International African American Museum in Charleston\, South Carolina. The garden draws inspiration from both the Lowcountry landscape and the broader African diaspora to create a tranquil environment for reflection\, learning\, and remembrance. Organized as a series of sub-gardens\, the design celebrates the artistry\, craftsmanship\, and labor of African Americans through botanical and material narratives. The African Origins Garden highlights the botanical diaspora by featuring plants commonly found throughout Southern landscapes that trace their origins to regions across Africa\, symbolizing how plant migration parallels the historical displacement and movement of people. Complementing this\, the Lowcountry Garden is rooted in the ecology of local marshlands\, incorporating native reeds\, a circular arrangement of concrete benches inspired by the contours of coastal mudflats\, and a gentle ground depression that gathers site runoff. Together\, these spaces form a contemplative memorial landscape that honors ancestral memory and offers visitors a profound connection to the enduring heritage of the African diaspora. \nHood Design Studio is a landscape architecture and social art practice based in Oakland\, California and founded by visionary landscape architect\, Walter Hood. Paul Peters\, a Principal at Hood Design Studio\, is renowned for spotlighting the intricate ties between nature and culture in his landscape designs. He transforms expansive sites into intimate spaces\, designing with sensitivity to personal memories and experiences. He is deeply invested in the conceptual phase\, seamlessly weaving broad perspectives\, conceptual thinking\, and research throughout his projects\, ultimately influencing societal perspectives. Earning his master’s in landscape architecture from the University of British Columbia\, Paul managed his own design-build firm in Vancouver for seven years. Since joining Hood Design Studio in 2016\, he’s pioneered several groundbreaking projects. Notably\, he’s contributed to the International African American Museum in Charleston\, SC\, the historic Oakland Museum of California’s renovation\, and Nvidia’s state-of-the-art campus in Silicon Valley. \nVirtual\n$15 AHS members/$20 non-members\nAll virtual programs are in ET\nRegister Here

SUMMARY:AHS LIVE: Bad Naturalist
DESCRIPTION:When Paula Whyman first climbed a peak in the foothills of the Blue Ridge Mountains in search of a home in the country\, she had no idea how quickly her tidy backyard ecology project would become a massive endeavor. She soon discovered just how much she had to learn about hands-on conservation work. Bad Naturalist is a memoir about Paula Whyman’s attempts to restore native meadows on a 200-acre mountaintop–about the obstacles she encountered\, the mistakes she made\, the failures and the all-important successes\, and the discoveries she made along the way. Douglas Tallamy calls Bad Naturalist “self-deprecating\, humorous\, and thoroughly engaging.” Washington Gardener calls it “glorious.” Whyman will share the story of her efforts to restore the land. \nBad Naturalist is Paula Whyman’s first book of nonfiction. Her earlier book\, You May See a Stranger\, is an award-winning linked short story collection. Her writing has appeared in The Washington Post and The American Scholar\, and in journals including McSweeney’s Quarterly\, Virginia Quarterly Review\, Ploughshares\, and The Hudson Review. She was awarded residencies by MacDowell\, Yaddo\, VCCA\, The Studios of Key West\, and Oak Spring Garden Foundation. Her work on this book was supported in part by the Maryland State Arts Council. She spends her time on a mountain in Virginia with her husband and a mercurial standard poodle. \nVirtual (*Please note\, this program will not be recorded)\n$15 AHS members/$20 non-members\nAll virtual programs are in ET\nRegister Here

SUMMARY:AHS LIVE: Indigenous Landscapes of Abundance
DESCRIPTION:This program will explore the historic land management practices of Indigenous women of the northern Great Plains\, with a focus on the Amskapi Piikani (or Blackfeet) women. Dr. LaPier will address the ways Indigenous women promoted the growth of prairie plants\, including domesticated food-plants\, cultivated food-plants and “wild” food-plants within the northern Great Plains. You will also learn about some of the ancient “lost crops\,” those food-plants that were cultivated in the distant past and are no longer in use. This program strives to engender conversation around Indigenous women’s role in creating sustainable landscapes of abundance. \nDr. Rosalyn LaPier is an award-winning Indigenous writer\, environmental historian\, and traditionally trained ethnobotanist who currently serves as a professor at University of Illinois and a research associate at the Smithsonian.

SUMMARY:AHS LIVE: Designing with Fragrant Flowers and Aromatic Foliage
DESCRIPTION:Ralph Waldo Emerson memorably said\, “The earth laughs in flowers\,” which captures the joy people find in cottage gardens and cheerful urban flower plantings. Unlike color\, fragrance is ephemeral\, invisible\, and hard to describe\, but just as powerful! It summons memories\, provides comfort\, and often takes gardeners and garden visitors to exotic parts of the world. In this session\, Christopher Sheridan will explore the language of fragrance\, share design strategies for scented plants\, review a classic classification system\, and journey through the scented bloom cycle. Get in the spirit and bring a new level of creativity and enjoyment to gardening\, flower arranging\, and garden touring. \nChristopher Barrett Sheridan\, The Flower Sommelier\, is a horticulturalist\, floral design instructor\, and aspiring historian\, specializing in scented plants\, heirloom flowers\, romantic garden design\, and Victorian floral traditions. Chris regularly offers immersive design workshops at Longwood Gardens and lectures at national events\, including the Philadelphia Flower Show and the International Master Gardener Conference.

SUMMARY:AHS LIVE: Mexican History of Botany
DESCRIPTION:In this talk\, Dr. Lopez will focus on the history of botany in Mexico (including the southwestern United States that were previously part of Mexico)\, drawing from his new book\, Rooted in Place: Botany\, Indigeneity\, and Art in the Construction of Mexican Nature\, 1570-1914. Rooted in Place traces historical transformations in the relationship between nature and imagined communities across three interlinked moments in the Renaissance\, the Enlightenment\, and the late nineteenth century in Mexico. It is the first major study of the relationship between understandings of nature and the creation of structures of rule within Mexico. The book intentionally weaves between environmental history\, history of science\, visual culture\, and political history. \nRick A. López is Anson D. Morse 1871 Professor of Latin American History and Environmental Studies at Amherst College. \nVirtual\n$15 AHS members/$20 non-members\nAll virtual programs are in ET\nRegister Here
