              Where Memories Bloom Forever


Armstrong-Kelley Park at 684 Main Street in Osterville, MA is owned and operated by the Cape Cod Horticultural Society. The society was established in 1928 and the land was given by generous patrons to the society in 1930. Cape Cod’s oldest and largest (8.5 acres) privately owned park open free to the public. Leashed pets welcome.
Over its 85 + years of history, Armstrong-Kelley has been building a greenspace for the residents of Osterville and the general public to enjoy. Come visit our 30 rare and unusual trees, as well as our trails, shady walkways, and specialty
gardens.  There are currently 1,400+ memorial boards encircling the Park.

Buddy's Place-Pet Memorial Garden


There are picnic tables and benches scattered throughout the acreage. 

We have a special place in our hearts for children of all ages.  We love it when families come to the Park.  We are committed to making the Park kid friendly and offer educational activities throughout the year.
The park is open to the public from dawn to dusk
throughout the year.  When there is a function, the park is closed for the privacy and enjoyment of the guests exclusively.


Pets are welcome at the Park provided they are leashed and owners provide and use pet disposal bags.  We love good dogs, not "bad ones."

Milestone Celebrated

We reached a major milestone (quite literally) at the Park this summer. The boardwalk system was created in 1998 and boards have been donated ever since stretching long and far around the Park.  

There are now over 1,400 memorial boards throughout the gardens.  The Woodland Walkway was full by early spring. 

The new boardwalk outlining Buddy's Place is now open. 

Is Buddy's Place just for Pets?

Some folks have asked us this.  The answer is:  No.  If you stroll the boardwalks you will already see many pets remembered among the existing boards.  The new area is no different.  The pet memorial stones are dedicated to Man's Best Friend, but the boardwalks are open to all two-legged and four-legged friends.


Volunteers spent over 100 people hours power washing and staining the boards this summer.  You'll notice the difference right away.
Thank you Grumpy Old Men and Gorgis Gals.

Thoughts about Gardening:
"Gardens are not made by singing 'Oh, how beautiful' and sitting in the shade."
--Rudyard Kipling
