Roswell Park Comprehensive Cancer Center is located in Buffalo, New York.  Our primary mission is medical care, research, education and prevention of cancer. Greenery enhances our campus environment but it must not become onerous as staffing is limited. Therefore, the planter selection was required to be impermeable to severe weather conditions, and hold a water supply for at least one week. Our first planter order was for the 9^th and 10^th floor south facing terraces of our new building. We continue to be very impressed with the performance and have since placed 2 more orders.
