EasternIowa CC's video: Episode 03: Witches Brooms and Reference Garden

In this podcast, we discuss a unique aspect of conifers known as a Witches Broom. These unique growths are often due to different stresses that can occur with these plants and often lead to novel growth patterns, colors, and arrangements. David Horst tells about how these have been incorporated into the collections at the arboretum, and how many of the witches’ brooms that are there are local growths that he himself has discovered and, in some cases, even had the opportunity to name. He also tells us how the arboretum became a reference garden by the American Conifer society and why that is important for the educational goals of the arboretum.
