5/1/2013 Garden Escapees Non-native Bamboos (Bambusa, Phyllostachys, Psuedosassa) • Evergreen and hardy to -25 F, these bamboos produce culms each season that grow to more than 30' in just weeks • Clumping bamboos not AS bad. Running = very bad! Honeysuckle overgrowing native trillium http://shltrip.com/sitebuilder/images/4s_bamboo_forest_in_Rutgers_G arden_IMG_9680-982x744.jpg Garden Escapees Asian (or Oriental) Bittersweet (Celastrus orbiculata) • Gardeners like it for its fast growth and attractive fruit • Aggressive invader. • Seeds are spread by birds to surrounding wild areas where it overgrows other plants smothering them and girdling tree trunks. Purple loosestrife (Lythrum salicaria) • Showy flowers make it gardeners’ favorite • Mature plant produces 2-3 million seeds per year. Garden Escapees • When reach wetland habitats grow rapidly, outcompeting native grasses, sedges and reducing habitat for waterfowl Periwinke (Vinca minor) • Forms dense carpet that excludes other species Garden Escapees • Grows most vigorously in moist soil with only partial sun, but it can grow in deepest shade, even in poor soil http://pics.davesgarden.com/pics/Equilibrium_1124078074_450.jpg http://www.hiltonpond.org/images/VincaMinorSpring01.jpg 4
5/1/2013 English Ivy (Hedera helix) • As it climbs it engulfs and kills tree branches by blocking light from reaching tree’s leaves • Extra weight can make trees more likely to lean and fall Garden Escapees Invasive Weeds Mile-a-minute weed (Polygonum perfoliatum) • Distinctive triangular blue green leaves, and curved spines on reddish green stems. • Seeds transported by birds and mammals • Vine overgrows and outcompetes native vegetation • Can bring down branches or whole trees with its weight http://www.massnrc.org/pests/pestFAQsheets/popup_code/mileaminutefig01.htm http://www.ec.gc.ca/eee-ias/4612AC81-3CB4-4AC4-BCE5-3D5845DEFF1B/Phragmites%20australis.JPG Invasive Weeds Common Reed (Phragmites australis) • Forms dense stands up to 15’ tall • Bushy flowers ripen from brown to grey and gain a fluffy appearance from hairs on seeds • Once in marsh, or disturbed habitat, rapidly forms monoculture, crowding out native plants, changing hydrology, altering wildlife habitat and increasing fire potential Invasive Weeds Garlic Mustard (Alliaria petiolata) • Leaves and stems emit distinctive garlic odor when crushed • Slender white taproot with distinctive “S” shape at top. • Seeds are dispersed on fur of mammals. • It spreads rapidly in woodland habitats, displacing native wildflowers • Primary spread is via human transport (hiking, mowing). http://www.phragmites.crad.ulaval.ca/Images/ACCUEIL.jpg http://commons.wikimedia.org/wiki/File:Alliaria_petiolata.png Invasive Weeds Japanese Stilt Grass (Microstegium vimineum) • Recognized by its lime-green color and shiny, slightly offcenter midrib • Forms dense monocultures that out-compete nearly all other plant life on forest floor, even in undisturbed habitats Invasive Weeds Japanese Knotweed (Polygonum cuspidatum) • Distinctive hollow red-tinged stems, heart shaped leaves and, in summer, lacy strands of tiny, white flowers • An aggressive invader, it is particularly problematic along rivers and stream banks where it forms dense stands and outcompetes native vegetation http://images.nbii.gov/ESellers/D_med-res/bansPicture%20044.jpg 5
