Featured Event
W.S. Merwin: A Talk and Poetry Reading
*Rescheduled from March 21* W.S. Merwin was famed for his poetry, winning the Pulitzer Prize for Poetry twice and named the United States Poet Laureate in 2010. But he was also a nature enthusiast with a deep concern for conservation. Merwin bought a plot of former agricultural land in Maui in 1977 and spent 40 years revitalizing the land, planting nearly 3,000 species of palm trees, and the estate is now recognized as one of the most important collections of palms in the world. Join us for a talk and poetry reading celebrating Merwin's legacy.
