Stopping the march of our worst weeds

How and when non-native ornamental plants, like agapanthus or bamboo, jump the garden fence and go rogue, is a major area of focus for Lincoln University plant bio-security professor, Phil Hulme. That's because they are the primary source of environmental weeds both worldwide and in Aotearoa. He and Professor Charles Perrings from Arizona State University have just been awarded a Marsden science grant to investigate how our garden preferences, as well as the price of plants can effect the distribution of invasive species.
