Acer palmatum is a species whose presence has been documented in the Wissahickon Park and the natural areas around the Morris Arboretum in Philadelphia as well as at the National Arboretum in Washington, D.C. With many cultivars having high seed yields, it is important to look into viability and germination rates as indicators of their invasiveness, as previously researched for Ailanthus altissima (Wickert et. al 2017). This project looks to compare these indices among cultivars to produce a recommendation of what cultivars might be better to plant in order to mitigate potential invasive effects.HorticulturePlant Breeding and GeneticsReport
