Elisabeth Miller was dedicated to the education of gardeners and relished the opportunity to share her insights with others and to bring knowledgeable horticulturalists to the Pacific Northwest to share their experiences. As a lasting gift to the horticultural community, the Pendleton and Elisabeth Carey Miller Charitable Foundation, the Elisabeth Carey Miller Botanical Garden, the Northwest Horticultural Society and the Elisabeth C. Miller Library sponsor a free annual memorial lecture to remember the legacy of Betty Miller.

The 2026 Elisabeth Carey Miller Memorial Lecture will feature Brian Thompson, Manager and Curator of Horticultural Literature and Rare Books, at the Elisabeth C. Miller Library. Brian will be retiring this year after more than 30 years with the Library. His topic will be announced later in August 2026.
