What’s Coming Up

Seasonal Experiences

Fall Color Watch Oct. 25th

Fall color continues to slowly spread on our grounds, transforming tree foliage with lush reds and golds. Sugar maple (Acer saccharum) and oakleaf hydrangea (Hydrangea quercifolia) are beginning to provide beautiful color at the arboretum. Tupelo (Nyssa sylvatica), Staghorn sumac (Rhus typhina), and highbush blueberry (Vaccinium corymbosum) are also still worth mentioning. Purchase tickets to visit arboretum. At the botanical garden, color is slower to arrive but festive displays of mums, pumpkins and seasonal planters are providing pops of fall hues. Tupelo (Nyssa sylvatica) can also be found at the botanical garden and the devil’s walking stick (Aralia spinosa) in C.K. Patrick Perennial garden, west side, has some nice purple-orange fall foliage. Purchase tickets to visit botanical garden.

Kalberer Emergent Tower and Murch Canopy Walk

Experience fall color from a new perspective at the Arboretum. The Murch Canopy Walk invites guests on a 500-foot-long elevated walkway that is built 65 feet above the forest floor. The Emergent Tower is 120 feet or approximately 12 stories tall and provides a breathtaking view of the surrounding area all the way to Lake Erie. Buy tickets here.

Tree of the Month: Tupelo

This selection has a very tight, upright habit unlike the species. The lustrous dark green summer foliage turns impressive shades of orange in early fall. The upright narrow habit is ideal for smaller spaces and as an urban tree. Black gums prefer full sun to partial shade and will thrive with almost no maintenance once established. Great tree for wildlife.
