In 2003, Lanoha Nurseries opened a multi-acre arboretum planted with a clearly labled mix of hardy trees, shrubs, and perennials. The various collections help give an idea of mature size and growth habits of the most reliable plant specimens for Nebraska landscapes. The arboretum offers scenic walking paths along numerous waterfalls and streams, showcasing materials suitable for any residential or commercial project.

The arboretum is a favorite spot for photography and enjoying the outdoors. Stroll through the covered bridge and view unique sculptures by local artists. It is open to the public during Garden Center hours.  Professional photographers should check in at the Garden Center before using the arboretum.
