One of the goals of the New Hampshire Federation of Garden Clubs is to help educate our citizens about some of the environmental issues which affect the quality of life of each one of us.
NON-NATIVE INVASIVE PLANTS are of great concern now among environmentalists, gardeners, and others, "as they are taking over our wetlands and other areas where native plants have lived for many years. Without the native plants, many species of wildlife will perish." (Virginia Grandpre' in the Stoddard Garden Club's Alien Invaders informational flier.)

 
The following is a list of invaders compiled from the Stoddard list, and from one put together by Catherine Schwenk in the year 2000.

Non-Native Invasive Plants Found in NH:
Autumn Olive (Elaeagnus umbellata)
Burning Bush ( Euonymus alatus)
Eurasian Watermilfoil (Myriophyllum spicatum)
Garlic Mustard (Alliaria petiolata)
Goutweed/Bishop's Weed (Aegopodium podagraria
Japanese Barberry (Berberis thunbergii)
Japanese Knotweed (Polygonum cuspidatum)
Multiflora Rose (Rosa multiflora)
Norway Maple (Acerplatanoides)
Oriental Bittersweet (Celastrus orbiculata)
Phragmites or Common Reed (Phragmites australis)
Purple Loosestrife (Lythrum salicaria)
Ragweed (Ambrosia artemisiifolia)
Russian Olive (Elaeagnus angustifolia)

None of these plants should be newly planted in any home garden, no matter how pretty they are. Any of them found should be removed (though that is often very difficult). Ask your garden center for alternates, and encourage them to find alternates if they are still selling invasives.
