The Arnold Arboretum provides both extensively documented collections for research and the facilities for the researchers—labs, greenhouses, and growing chambers. From around the world, scientists come to use the trees and shrubs in the Arboretum landscape, studying climate change, plant evolution, natural selection, and species adaptation. Join docent Esther Miller to hear about the science of the Arboretum.

With nearly 4,000 different kinds of plants represented in the Arboretum's living collections, every day presents rich opportunities to see something new. If you enjoy learning about plants and their unique characteristics, you can contribute to science as a participant in the Arnold Arboretum's Tree Spotters program. This citizen science project opens a window into the Arboretum's phenology: the timing of natural events, such as the leafing out and flowering of trees in the spring and changing foliage colors in the fall. Your observations will assist Arboretum scientists in their...

What better place to look for the differences between angiosperms (plants that flower and have enclosed seeds), and gymnosperms (plants with "naked seeds," including conifers, ginkgos and others), than in the Arnold Arboretum landscape, where over 15,000 plants reside in a living museum.

The Arnold Arboretum is full of spectacular specimens from around the world that any visitor will appreciate. However, what they observe is only half the story. How a tree uptakes water and nutrients, stays grounded in place, stores energy, and sometimes even propagates itself, is all thanks to its roots. Join horticulturists Andrew Gapinski and Conor Guidarelli as they unearth these questions and more during an exclusive look into the extraordinary world of roots.

Manager of Plant Production, Tiffany Enzenbacher, will discuss the Arnold Arboretum's propagule collection and documentation procedure. She will also display some of the different types of fruits, nuts, and seeds that are in the process of becoming the next generation of Arboretum plants. Seed showcased will be those collected during Tiffany's 2018 expedition to the Ozarks, as well as those collected on other institutional collecting trips.
