Great Horned Owl Walk

Arnold Arboretum

Dusk in November is a perfect time to look and listen for Great Horned Owls, often heard calling throughout the Arboretum’s collections. Join Horticulturist Brendan Keegan to hear about the owls' breeding and nesting behavior, learn how to go owling ethically, and possibly hear and see a few owls as well.

Workshop: Botanical Cyanotype

Arnold Arboretum

Make beautiful seasonal cards and prints using the alternative photography method known as Cyanotype. Participants will collect leaves and seeds in the landscape and arrange them on special paper to create a deep blue print with bright, ghost-white silhouettes. This historic photography method offers participants the ability to perform something that seems like magic.

Conifer Walk

Arnold Arboretum

What is a conifer, exactly? How is it different from an evergreen, or a gymnosperm? Join docent Paul Eldrenkamp as he leads us through the different types of conifers and how to identify them, the reasons behind their distinctive needle-like forms, and their rise and fall in evolutionary history.

Foraging Walk: Tea Time at the Arboretum

Arnold Arboretum

Join us for a winter foraging walk to learn what wild plants can be foraged and brewed into tea. Visit some of the Arboretum's tastiest winter plants, from sweet birch and sweet fern to sassafras and spicebush. You may even get to taste some of the teas yourself!
