I found a couple of clumps of these down by the edge of the pond. Now I'm confused, I read in one place that this is used sometimes in waste water ponds because of its ability to adsorb heavy metals, which sounds like a good thing but then, I also read that it has been designated as an invasive species which can reduce habitat available for wildlife, including native fish habitat and bird nesting and rearing sites. So now I'm not sure if finding this is a good thing, or not.
doesn't it look lovely. one of the problem with lovely plants that are not native is that they seem like a good idea at the time, then it turns out there are cons for all the pros after all
