Dow Wildflower Sanctuary

Established in 1999 by biology professor Dr. Paul Olexia, the Dow Wildflower Sanctuary provides an urban, living laboratory to feed curiosity, educate, and invite exploration. Over the years, more than 50 species of plants native to Michigan have been added to and are thriving on this hillside (see photos below). These plants are adapted to local conditions and help sustain a diversity of pollinators, herbivores and seed consumers. The sanctuary is used as an educational space for K classes and as a showcase for alternative, sustainable landscaping. 

The Wildflower Sanctuary is located on the east side of the Dow Science Center, beside the stairs leading to the tennis courts. We invite you to drop by and explore!

For more information on native plants, see the Resource section at the bottom of this page.
