Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130
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.
Dana Greenhouse, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130
Learn about seed biology, embryo dormancy, and factors present in woody plant seeds. The class will focus on seed storage and various treatment techniques, including over-wintering and aftercare. Appropriate for those who have succeeded at growing some plants from seed and are ready for greater challenges. Post-class nurturing will be required. Fee $55 members; $68 non-members.

To paraphrase Louis Pasteur, sometimes luck favors the prepared mind, as when Alexander Fleming discovered penicillin by noticing that mold growing accidentally in his lab seemed to kill bacteria. This 2018 Radcliffe Institute science symposium will focus on how scientists explore realities they cannot anticipate. Speakers from across the disciplines of modern science will present personal experiences and discuss how to train scientists, educators, and funders to foster the expertise and open-mindedness needed to reveal undiscovered aspects of the world around us.

Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...
At the Center for Astrophysics, we exploit quantum physics to advance the state-of-the-art in measurement and imaging, and then apply these tools to search for Earth-like planets around other stars and probe the nature, history, and fate of the Universe. Sometimes, these quantum tools can also be applied to down-to-Earth problems — ranging from health to navigation.

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.

Coral reefs support more than a quarter of all marine life, yet many are critically endangered. In the Florida Keys, the once common elk horn coral (Acropora palmata) has experienced steep declines since the 1970s. Preliminary blame was attributed to global warming and coral bleaching, but in fact, a human bacterial pathogen associated with a wide range of serious infections was the culprit. James Porter will discuss how Key West residents are saving these reefs...

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 our 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...
