Hickories in Horticulture: Novel Options for Diversifying Managed Landscapes

As severe weather events and the introduction of invasive pests occur more frequently in the United States, limited biodiversity and the resiliency of managed landscapes has come into question. Those that manage green spaces recognize the value of diversifying urban forests with species and selections of plants capable of tolerating the demands of a changing landscape and climate. Yet modern trends in the nursery supply chain have led to the repetitive use of easily grown, closely related taxa. Of the multitude of underutilized trees that could be used more broadly in managed landscapes are hickories [Carya (Nutt.)]. The genus Carya includes many stately, native trees, that offer superior ornamental features with great promise for application in urban environments. Hickories (Carya spp.) have long been sought after by horticulturists for their ornamental value yet have not been integrated into commercial nursery production due to limited propagation techniques, slow growth, and claims of poor transplant success. A focused interest in planting these trees could drive their development as nursery crops while research aimed at resolving production issues could expand their availability in the green industry. In this presentation we will introduce species of hickory with potential for application in Minnesota as well as review myths and current issues with their integration into horticulture.
