Cape Cod Horticultural Society
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 80 + 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, walkways, and specialty gardens.

• 250 rhododendron
• Umbrella and big leaf magnolias, Japanese cedars, and stewartia

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.
