Feel free to wander over
the Arboretum property and to create your own route to and from
the Visitors' Center. The map provided here (& also at the Visitors'
Center) should insure that you will be able to find your way, and
the level topography of the site should enable you to spot landmarks
such as the Far Barn from most vantage points. However, we should
like to suggest that your visit include one or more of the following
destinations.
POLLY’S PLAY PEN.
This rectangular area measuring 286 feet long by 35 feet wide on
the southwestern edge of the property is fenced to protect the plants
growing there from rabbits and deer. Included in the area are many
of the Polly’s plant introductions, including the famous North Tisbury
azaleas. Other rare plants, such as the beautiful Himalayan Daphne
genkwa, and Shortia galacifolia from the southern Appalachians grow
in association with hardy Camellia cultivars and a wide variety
of other rare and interesting species.

THE DOGWOOD ALLÉE
Beginning at the "Gym" and extending 284 feet is an astonishing
allée of the Kousa Dogwood, a species native to China and Japan.
Flowering from the middle of June into July, these spectacular plants
are among the finest small trees for home landscapes in the New
England region. Several of the trees forming the allée are Polly’s
introductions, selected for their habit of growth, bract characters,
and fruit size and color.

THE PLEACHED HORNBEAM ARBOR
In the southeast corner of the Arboretum
near State Road is a horticultural folly, which is the result of
years of careful training and pruning. Sometimes referred to as
the "Tunnel of Love," this curiosity was begun in 1964, and each
tree of Carpinus betulus var. columnaris that
comprises the arbor was carefully trained and pruned or sheared
until the tunnel was completed. Even now, the trees are pruned on
an annual basis to maintain the wonderful arbor.
