The elevated Central Artery running through downtown Boston was dismantled starting in 2004 as part of the Big Dig. The automobile traffic that would have taken the highway now moves below ground. In its place, Boston got the Greenway. On Thursday, I took a tour of the Greenway parks.
The tour was led by Darrah Cole and Anthony Ruggiero, horticulturists working for the Greenway Conservancy, the non-profit group that manages the parks.
Our group started at the Chinatown gate. The park there has reduced green space because the community asked for a plaza where they could hold events. One end of the plaza is lined with Dutch elm-resistant ‘Frontier’ elms. These elms are a hybrid of the European field elm (Ulmus minor) and the Chinese elm (Ulmus parvifolia).
Due to a warm early spring this year, the peak bloom for most of the lilacs at the Arnold Arboretum was the weekend of April 21-22. However, over a month later, a few varieties are still in bloom (date of accession in parentheses):
Syringa x prestoniae ‘Donald Wyman’ (1991) – Donald Wyman lilac
Syringa x swegiflexa (1949) – Swegiflexa lilac
Syringa sweginzowii (1977) – Chengtu lilac
Syringa tomentella (1999) – Felty lilac
Syringa villosa (1907) – Late lilac
Syringa [Villosae group] ‘Mary C Bingham’ (1998) – Mary C Bingham lilac
