American Horticultural Society (AHS) Reciprocity

Klehm Arboretum & Botanic Garden participates in the American Horticultural Society reciprocity program.  The AHS Reciprocal Admissions Program offers free admission and/or additional benefits at over 300 gardens throughout North America and the Cayman Islands.  Klehm Arboretum & Botanic Garden honors members belonging to participating gardens that fall outside the Rockford, IL area. Members must present their membership card.


Restrooms and water fountains can be found in the Visitor’s Center and on the south side of the Clarcor Pavilion.


  • All buildings and paved garden paths and trails are accessible to strollers and wheelchairs.
  • A wheelchair is available at the Visitor’s Center.
  • Our Klehm Express is an accessible vehicle for tours up to 12 people.

Friendly, leashed dogs are welcome, too.


Our gift shop, also located inside the Visitor’s Center, carries a variety of unique items from garden tools and gifts to toys and trinkets.  We also feature the works of local artists.  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.


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 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?


Do you like a challenge? There are two caches hidden within the grounds. 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 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 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.
