We are sad to learn of the passing of Dr. Peter Raven. Peter was long associated with NTBG and a recipient of the Robert Allerton Award for Excellence in Tropical Botany. The positive impact he had on fellow botanists will continue long into the future. https://t.co/R3kFhlEzFG

Glad to see Kevin, our plant records manager, presenting at the LIS Research Forum at @uhmanoa. Many people aren't aware of the importance of documenting and managing plant records for a botanical garden.

Sharing a palm poem by writer W.S. Merwin, a great friend of NTBG and long-time resident and palm collector on #Maui. We remember William and his garden fondly. The poem was shared by The Merwin Conservancy.
