The Conifer Collection is comprised of 576 gymnosperm taxa (kinds) representing 210 species, 31 genera, and 9 families. The main tract occupies twenty-four acres (10 hectares; excludes Hemlock Hill) and is arranged to facilitate the study of cone-bearing plants. Just like flowering plants, conifers form seeds. However, instead of being enclosed in fleshy fruits, the seeds of conifers are protected in cones. These seed cones are the female reproductive structures of conifers. Conifers also have pollen-bearing cones, which are the male reproductive structures. Male and female cones can occur on the same plant or on separate plants. Accurate identification of conifers requires an examination of the cones; however, leaf (needle) characteristics are also important clues to identification. Historic views of the conifers are made available by the Arnold Arboretum Horticultural Library.
The south entry for Conifer Path begins just inside Walter Street Gate, amid a grove of larch trees (Larix spp.). The path begins less than a minute’s walk from Walter Street Gate, and about a two-minute walk from Bussey Street Gate. The north entry for Conifer Path is along Valley Road, opposite the oak collection. This entrance is closest to Centre Street Gate (about a five-minute walk away); it is about twenty minutes from Forest Hills Gate and about thirty minutes from the Arborway Gate. In addition to Conifer Path, the conifer collection can be viewed from Hemlock Hill Road; a small footbridge across Bussey Brook provides limited access. Additional conifers may be viewed throughout the Arboretum landscape, particularly on Hemlock Hill and near the Peters Hill Gate. If driving, park outside the Centre Street Gate, Walter Street Gate, or along Bussey Street.
Conifer Path is composed of crushed stone and covers terrain that includes occasional mild inclines; the entrance from the Walter Street Gate is moderately steep. Many plants in the collection are sited off the path in grassy clearings. In winter, access may be limited by snow and ice; please use caution.
A self-guided tour of Conifer Path is available online or in the Visitor Center. An interpretive sign is posted near the Valley Road entrance to Conifer Path and provides a brief introduction to conifers.

How long should I explore?
Conifer Path is approximately ½ mile long. While it takes about fifteen minutes to walk, one can easily spend more than an hour exploring conifers on and off the path.
