One tree, two tree, red tree, orange tree.

Across the river in Jamaica Plains, the Arnold Arboretum of Harvard University is a public park and botanical research institution open to all. Established in 1872, the park boasts more than 2,000 different species and 16,000 individual plants in addition to the vibrant fall foliage of Boston’s autumn.

Bright red trees greet visitors as soon as they enter the gate by the visitor center.

Linden Path is one of the unpaved routes that visitors can take through the trees. At the end of the path, visitors can continue onto the Larz Anderson Bonsai Collection.

Along the main paved path, visitors see a full spectrum of fall colors from the trees.

The Bradley Rosaceous Collection is located by the Forest Hill Gates off of the Arborway. While peak bloom is from late April to mid May, visitors can still see some roses in the fall.

While visiting the Rosaceous Collection, visitors will see other bright colors in addition to the red, orange, and yellow of autumn.

The Arboretum was designed by landscape architect Frederick Law Olmsted and Charles Sprague Sargent, Class of 1862, as part of the Emerald Necklace — a chain of parks throughout Boston.

Some leaves display the transition from yellow to red that paint the beautiful autumnal palette.

Birds and squirrels are still enjoying the pleasant weather before winter strikes.
