The Beech/Central Avenues Corridor

Good landscape design weighs the different functional and aesthetic variables in play, whether the challenge is an historic landscape or a rooftop garden. Mount Auburn’s stewardship of its historic landscape relies on a careful mix of guidelines, policies, and strategic initiatives. It also utilizes archival reports and correspondence held by our Historical Collections Department. Occasionally, something more is called for. A recent project to renovate the “Beech/Central Avenues Corridor” illustrates the kind of extra steps we sometimes take in the design process.

The project site, situated in the historic core of the Cemetery on a rise overlooking the front gates, is in a prominent location with a high volume of visitors. It is bracketed by landscapes of contrasting characters. To the east, dropping down to Narcissus Path, lies a steep ridge whose  slopes in 2012 were planted with protective native species to create a wildlife habitat corridor. To the west at Bigelow Chapel and along Cypress Avenue, by contrast, we find highly ornamental Victorian period plantings. One objective for the landscape renovation was to create a transition zone between these two contrasting areas. In addition, the renovation needed to address the overall goals of increasing biodiversity in the horticultural collections, reducing energy costs in landscape maintenance, and protecting our significant historic monuments.

One such monument commemorates Dr. Jacob Bigelow, one of Mount Auburn’s founders and a long-serving president. The Bigelow lot already conforms to the general parameters of the project’s conceptual plan—naturalistic woodland understory plants with an historically appropriate un-mowed turf, using Pennsylvania Sedge (Carex pensylvanica)—but we felt that something special should be done there.

 

Research helped us identify what sort of planting Dr. Bigelow might have liked. His book Florula Bostoniensis (1814), a seminal work on the plants found in eastern Massachusetts in the early 1800s, pointed the way. Although it is a scientific flora, the book occasionally betrays his feelings about certain plants. For instance, he calls attention to the Sweetbay Magnolia (Magnolia virginiana) growing in Gloucester, the only stand of this species north of New Jersey. In 2010, Mount Auburn’s Kelly Sullivan collected seed in the very swamp where it grew two hundred years ago. Two trees grown from this seed in our nursery are now ready to be planted.

Plant Records Manager Steve Jackson found other favorites as he combed through Bigelow’s book. Of one species, Bigelow writes, “We do not have a plant that surpasses this in elegance.” Another he describes as “A singular and beautiful plant, found upon dry hills.” Thus, our planting plan now includes American Holly (Ilex opaca), Bunchberry (Cornus canadensis), Swamp Azalea (Rhododendron viscosum), Mountain Laurel (Kalmia latifolia), Cranesbill (Geranium maculatum), and Lupine (Lupinus perrenis). These beautiful natives not only honor Dr. Bigelow’s sentiments but also make an elegant bridge between the Victorian and the rustic in the Beech/Central Avenues Corridor.

Below are photos taken before and during the planting process near the monument to Boston merchant and philanthropist Thomas Handasyd Perkins above. Perkins commissioned America’s first professional sculptor, Horatio Greenough to carve his Newfoundland dog. The monument was originally placed at Mount Auburn Cemetery in 1844, and is viewed by many as a symbol of loyalty and companionship, and a guide through the afterlife.

 

A list of the final plantings in the Beech Corridor area can be seen below.  Mount Auburn’s staff removed some declining hemlocks and other trees, and planted a dozen new trees in the fall of 2015. The final planting of 157 shrubs and 7,700 herbaceous perennials and groundcovers was completed in June 2016.

    I notice that most of the plants listed are cultivars. I’ve found out that cultivars, in general, are not host plants and do not support pollinators. Has research been done to ascertain that these chosen cultivars do, in fact, fully support pollinators? I mean, do they serve as hosts plants?

    • Jennifer Johnston says:

      Insects do not discriminate against cultivars. In fact, research shows that many attract more visitors than the non-cultivars do. The nectar is just as good. The only drawback, from a wildlife perspective, is that sometimes cultivars are sterile (they don’t produce viable seed).

      The concept is discussed at length in several recent books by Nigel Dunnett and James Hitchmough (designers of London’s Olympic gardens) and by Piet Oudolf (designer of the Highline & others).

    Tremendous work! It is quite beautiful and inspiring. We have recently started to utilize similar native Carex species around several of our historic trees. Very exciting to see your before and after photos—keep up the good work!
