Plant Spotlight on Sorbus alnifolia
A delight to behold in the landscape, Sorbus alnifolia
stands in a class of its own among mountain ashes. In contrast to its
American and European relatives, which feature compound leaves, Korean
mountain ash bears simple, glossy leaves. These turn shades of yellow,
orange, and rust in October, providing a stunning backdrop for its
display of showy red fruits. S. alnifolia makes a fine specimen
tree, and has proven to be quite hardy and more tolerant of heat,
drought, and insect stresses than other mountain ashes. A massive
centenarian grows on the south slope of Peters Hill, and a striking
specimen stands among the oaks between Bussey Hill and Valley Roads.

Enhance Dawson Pond
Dawson Pond, one of three man-made ponds near the
intersection of Meadow and Bussey Hill Roads, is a favored destination
for visitors and wildlife alike. This year, horticulture staff initiated
pond enhancements with the replanting of accessions of the endangered
Nantucket juneberry (Amelanchier nantucketensis) along its
southern edge. In August, remediation of the pond's banks began with the
addition of aquatic herbaceous plants including arrowhead (Sagittaria
latifolia) and pickerelweed (Pontederia cordata). Staff will
prepare the edges of the pond this autumn for spring planting by removing
invasive plants and treating the soil. Summer 2010 plans call for the
installation of a new cobble landing at the pond's northern edge to
provide a convenient overlook for visitors.
