Knotweed Parfait

Nothing to Fear, but Fear Itself

Reynoutria japonica Houtt. (Japanese knotweed)

Godzilla-like, swaggering through our communities, Japanese knotweed is choking our waterways, breaking apart foundations, consuming whole houses and costing our cash-strapped economy millions of dollars per year in repair and mitigation. Ranked among the World’s 100 Worst Weeds, it is illegal to propagate the plant in England. It’s banned in Connecticut, Massachusetts, New Hampshire and Oregon and is considered a noxious weed in Alabama, California, Vermont and Washington.

What to do? Eat dessert! Yes, that’s right: dessert! Enjoy a beautiful lime-green parfait and do your part to halt Godzilla in her tracks (the plants are mostly females). Here’s how:

You’ll need about a dozen knotweed canes, harvested when they’re only about two feet tall–the thicker the better. Use a sharp knife and cut them off at the soil line. And don’t tell me you can’t find any! The plant occurs in 39 of the 50 states and is especially abundant on the east coast. No one will begrudge you for cutting them down. You can’t even mistake them for anything else. No other plant in North America grows six feet tall from thick, hollow, fleshy stems that are swollen at the nodes, has large, green oval- or heart-shaped leaves and produces numerous sprays of off-white flowers and small, winged fruits late in the season.

Wetland Invaders

What the heck is Phragmites? I found myself posing the same question. What could be so diabolical, so absolutely devilish as to demand several days’ sweat and muscle ache shoveling out a muddy pit? Why the misleading singular noun? Sadly (and despite the phonetic similarities), Phragmites has nothing to do with Fraggle Rock. Neither is it related to flaming space junk, or the stone spikes that spur the floors and ceilings of winding underground caverns. Nope–it’s a plant. And, to many, it’s a ruthless swampland invader.

A Worthy Event: EcoHackNYC

Ed. note: This is a guest post from Andrew Hill, Senior Scientist at Vizzuality, a small company specializing in data, GIS, and the Web. As an organization that is deeply concerned with biodiversity and conservation, the Garden is invested in using technology as a scientific tool, and I feel EcoHackNYC is an event worth sharing with the rest of the New York-area scientific community. If you’re a scientist or researcher, please consider joining this event. — Ann

This weekend, for the second time in under a year, we are throwing an event to bring together scientists, developers, designers, and others to work collaboratively on environmental projects that matter. We call this event EcoHackNYC. It is a free (un)conference where a small group of people present projects, problems, or data they think need to be developed, and then larger groups of enthusiasts and experts work tirelessly to develop solutions (also check out last year’s event here). For us, this is a special event.

Morning Eye Candy: A.M. Architecture

A late MEC today, but not forgotten. I blame the interminable train delays. Seeing the tulip trees in their spring garb makes for a good balm on commuter frustration, though.
