Thursday, March 23, 6:30 pm – 8:00 pm Eastern – Plant Exploration, Then and Now, Live and Online

The Arnold Arboretum has been collecting plants from around the world for 150 years, but plant exploration today looks very different than it did in the 1800s. From changes in collecting practices to an evolving relationship between the Arboretum and its international partners, a lot has changed in the last century. Join Head of the Library and Archives Lisa Pearson and Keeper of the Living Collections Michael Dosmann on March 23 at 6:30 pm in the Weld Hill Research Building, 1300 Center Street in Boston, to learn what these trips were like in the days of yore, and what they are like now.  To register for the in person program, click here.

Parking is available on-site at the Weld Hill Research Building. Find directions here. 

This event will also be livestreamed to YouTube. To sign up for the virtual livestream instead, click here.


Wednesday, March 22, 12:30 pm – 3:30 pm Eastern – Orchids of New England Webinar

Orchidaceae is one of the largest plant families in the world, and there are 50 orchid species native to New England, from showy lady’s slipper (Cypripedium reginae) to rose pogonia (Pogonia ophioglossoides). While some species are common, many are of conservation concern. This session with Neela de Zoysa on March 22 from 12:30 – 3:30 provides context for understanding native orchid habitats, diversity, and conservation issues. You will learn identification techniques, pollination strategies, and life-cycle stages for native orchids. This class is now offered as a webinar, and is $60 for NPT members, $72 for nonmembers. Register at http://www.nativeplanttrust.org/events/orchids-new-england/. Please note: We do not make video or audio recordings of classes or programs available after the fact, because we believe education is interactive, with instructors and students building a community and culture of learning. Some programs may be recorded strictly for instructor-training purposes.
