Banned in Boston - Invasives

Plants Banned in Boston (and Massachusetts in general)--

Last spring I came across a publication from the Massachusetts Division of Fisheries & Wildlife -- "A Guide to Invasive Plants in Massachusetts" by Pamela B. Weatherbee, Paul Somers and Tim Simmons. It would seem that the catchy phrase "Banned in Boston" should apply to these plants, too.

They list the following:
Black Locust (Robinia pseudoacacia),
Norway Maple (Acer platanoides),
Oriental Bittersweet (Celastrus orbiculata),
Japanese Barberry (Berberis thunbergii),
Black Swallow-wort (Cynanchum louiseae),
Shining and Common Buckthorn (Rhamnus frangula and R. cathartica),
Japanese Honeysuckle (Lonicera japonica),
Morrow's Honeysuckle and other shrub honeysuckles (Lonicera morrowii, L. tatarica, L. maackii, L. xbella).

Also: Autumn Olive (Elaeagnus umbellata),
Porcelain Berry (Ampelopsis brevipedunculata),
Multiflora Rose (Rosa multiflora),
Goutweed/Bishop's Weed (Aegopodium podagraria),
Yellow Iris (Iris pseudacorus),
Japanese Knotweed/Bamboo (Pollygonum cuspidatum),
Purple Loosetrife (Lythrum salicaria),
Garlic Mustard (Alliaria petiolata), and
Phragmites/Common Reed (Phragmites australis).

They also list as "Problem Plants to Watch For":
Princess Tree (Paulownia tomentosa),
Western and Chinese Catalpa (Catalpa speciosa and C. ovata),
Hardy Kiwi (Actinidia arguta),
Winged Euonymus, Wahoo or Burning Bush (Euonymus alata),
Kudzu (Pueraria montana var. lobata),
Mile-A-Minute Plant (Polygonum perfoliatum),
Japanese Stilt Grass (Microstegium vimineum),
English Water Grass (Glyceria maxima), and
Eulalia Ornamental Grass (Miscanthus sinensis).

Many of these plants are sold at local garden centers and are available through catalogs. Adding to the problem is the fact that their photos are beautiful and we fall in love with them. Unfortunately, some of them have found their way into my own garden. I have much work ahead of me.
