Garlic mustard (Alliaria petiolata), is an obligate biennial herb of the mustard family (Brassicaceae). Seedlings emerge in spring and form basal rosettes by midsummer. Immature plants overwinter as basal rosettes that stay green and continue to grow during snow-free periods when temperatures are above freezing. Continue reading "Garlic Mustard: Odiferous Invader"
When frogs are afraid to go into the water, should we be worried, too? After Sally Pick, a Wild Ones Partner-at-Large (MA), called me in response to a note about malformed frogs in the January “Grapevine,” I felt compelled to hit the stacks.

The notion of invasiveness in native plants is one that is distasteful to contemplate. Usually we prefer to say that a native plant is a “strong spreader” or an “aggressive spreader.” At some point it may be necessary to stop splitting hairs. I’m thinking particularly of cup-plant (Silphium perfoliatum). It first caught my attention when […] Continue reading "The Grapevine (Jan 2006)"
Ringing the alarm for Earth “An ecosystem itself undamaged is very, very resilient, and the more simplified it gets, the less resilient. Globally, what we are doing is simplifying them all, simultaneously, which is a very dangerous large-scale experiment.” Peter Raven, botanist, recently Time magazine’s “Hero of the Planet,” Director of Missouri Botanical Gardens in […] Continue reading "The Grapevine (Nov 2005)"

Imagine Imagine all the most searing yellows from Van Gogh’s sunflowers, the most sumptuously gorgeous reds and oranges of O’Keefe’s poppies, and the smoky blues and magentas made familiar by Monet’s water lilies. Spread these colors over a landscape as far as the eye can see. Hold tight to that image in your mind while […] Continue reading "The Grapevine (May 2005)"
Water You Gonna Do About It? In 1917, during World War I, the Washington State Legislature passed a bill which reads, in part, “… all waters within the state belong to the public, and any right thereto, or to the use thereof, shall be hereafter acquired only by appropriation for a beneficial use and in […] Continue reading "The Grapevine (Mar 2005)"
Plant Diversity and Ecosystem Functioning In a study that mimicked the natural order of species loss in a grassland ecosystem, researchers found that declining biodiversity greatly reduced resistance to invasive species, and that the presence of even small numbers of rare species had profound functional effects. The results have important implications for understanding the biodiversity […] Continue reading "The Grapevine (Jan 2005)"
