The Betty Jayne and Kenneth Dahlberg Welcoming Terrace is the first entry to the Arboretum’s gardens and collections upon leaving the McQuinn Great Hall of the Oswald Visitor Center. Its unique combination of plants whose leaf color is either reddish/maroon green, chartreuse green or blue green creates a stunning effect. It is the place where families meet, garden tours start and some events are held. No other garden at the Arboretum has this color scheme.
