Propagation of Historic Lineages

Sean Halloran, Plant Propagator
The Arnold Arboretum curates and maintains one of the most historic and well-documented collections of woody temperate species. We are in the midst of a 10 year Campaign for the Living Collections, and that means we will add even more diversity to those living collections. In order to maintain the diversity that already exists, great care is taken by our landscape horticulturists to report plants that are potentially threatened by weather, pests, and diseases. The Plant Propagation department is tasked with the propagation of those vulnerable and important historic lineages, in order for that plant to be returned to the living collections. On this tour, Arnold Arboretum propagator, Sean Halloran, will illustrate the traditional and novel techniques employed in order to preserve these culturally and historically significant collections. Grafting, air-layering, hardwood cuttings, the Bonsai and Penjing Collection, and more will be discussed with real examples and the incredible stories behind them.

Please enter through the inside gate to the Dana Greenhouses' driveway for this tour, and then go to the door of the greenhouses. If needed, call for directions, 617 384-5209.
