              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. 
Park Features include:
• Franklinia tree, virtually unknown in the wild
• 250 rhododendron
• Umbrella &big leaf magnolias, Japanese cedars, & stewartia
• A holly dell
• The John Folk Water garden
• Wetland, Woodland, Monge, and Buddy Place  walkways with over 1,400 donated boards

• Seven hillside trails & Heath Hillside

• Liam’s train and Liam’s View
• Garden of verses

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."

There's always room for a wagging tail or two at the Park.  Read about Buddy's Place. The new boardwalk and memorial pet stone area is tucked behind the big holly tree on the green.  We already have 12 stones and a dozen boards and a bench.  Look for "Buddy" at the entrance.

      Get a stone or board.
