Holly writes and presents horticultural lectures, workshops, and garden tours on a variety of topics, for both professional and amateur audiences.
She has lectured about starting a public garden, the garden as an oasis, anything related to herbs, fragrance and flavor, antique roses, great plants, historic gardens, native plants, garden design, sustainable gardens, children’s gardens, and gardens around the world, and much more.
A few times each year, Holly hosts garden travel programs, providing a more in-depth and unique exploration of horticulture and gardens around the world. Recent trips include Costa Rica Watercolors (co-hosted with Bonnie Lundy, artist), Historic Sites & Gardens of Malta and Eastern Sicily (with the American Horticultural Society), and Sacred Gardens and Temples of Japan (with Friends of the National Arboretum).
