Flowering Magnolia garden store:

The Flowering Magnolia garden store, also located inside the Visitor’s Center, carries a variety of unique items from garden tools and gifts to toys and apparel. We thank you for your purchases, as all store proceeds benefit Klehm Arboretum, and its education and outreach programs. Members of the Arboretum receive a 10% discount on all purchases.  We accept handcrafted consignments.  For more info click here.


The Harding Horticultural Library is housed inside the Visitor’s Center and is available whenever the building is open. It is a reading and reference library providing information about botany and horticulture to Klehm Arboretum staff, volunteers, members, professional horticulturists, students, gardeners and the public.

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 Klehmentine 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?


Do you like a challenge? There are two caches hidden within the gardens. Both Klehmantine’s Stash – N 42° 14.582 W 089° 07.200 and Cow-li-Flower’s Cache – N 42° 14.667 W 089° 07.433 are small size caches. Hint: They are quite a walk from the parking lot and hard to get to in the winter. Please log your comments on Have fun!

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 on trees or hanging from branches. Climbing is invited on play structures and certain exhibits where 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 or in-line skates. Respect others in your group and other visitors. Photos and video for personal use are welcome.
