Klehm Mascots

Klehm Arboretum is also home to three truly unique garden creatures that provide a whimsy and a sense of fun to our grounds. Cow-li-flower and Klehmantine live hidden in the Nancy Olson Children’s Garden. And Flora Fauna keeps company with some of the Arboretum’s oldest residents in the Prehistoric Garden. Can you find all three mascots?

Arboretum Etiquette:

Our grounds are kept beautiful and healthy for enjoyment and learning. We hope you take advantage of our expansive grounds, and explore the diversity of tree collections offered. Thank you in advance for your cooperation.

Be Kind

It is permissible to pick up leaves, seeds, or cones that have fallen to the ground, but please refrain from picking leaves, fruits, or seedheads from trees or other plants. Stay on paved paths, nature trails, and grass. Footsteps elsewhere crush plants and damage soil. Leave everything here for others to enjoy.

Be Safe

Please, no climbing trees or hanging from branches. Climbing is invited on play structures and certain exhibits were noted by signs. Only leashed, well-behaved pets are allowed on the grounds. Please clean up after your pet. Pets may NOT be left in cars during your visit.

Be Respectful

Children must be accompanied by an adult. No scooters, skateboards, bicylces or in-line skates. Respect others in your group and other visitors. Photos and video for personal use are welcome.
