The sprays of white flowers in the foreground belong to false bamboo, a non-native, very invasive species. Most nurseries here will no longer sell it. In the background, in front of the trees, is an extensive growth of common reed grass (Phragmites australis) another serious invasive that invades wet sites, ditches, edges of wetlands, displacing other vegetation. In between is a huge patch of common burdock (Arctium minus), another invasive. Nearby, but out of the photo, is pale swallowwort (Cynanchum rossicum), the most insidious invasive species, and thousands of buckthorn (Rhamnus) shrubs, yet another serious invasive species!!
