GMO Escape An experimental, genetically modified grass, designed for golf courses, has been found in the wild, several miles from its test site.

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)"
