Ornamental Horticulture

Areas of research focus on testing of plant species and hardware materials for green roofs; cultivar evaluations, cultural practices and pest control for Christmas trees; and roadside vegetation management. The effect of air pollutants on plant growth is being investigated.

Ornamental Horticulture researchers working in the Department of Plant Science at Penn State.

The Center, the only location in North America with small test green roofs on replicated buildings, characterizes and quantifies the performance of green roofs and promotes their discoveries through education and outreach.

This research focuses on all aspects of roadside vegetation management, using an Integrated Vegetation Management approach. The aim is to preserve as much desirable vegetation as possible while minimizing undesirable vegetation and maintaining a desirable aesthetic, within the confines of limited resources.
