Alyssum planted to extract nickel now invades Oregon valley

Some plants can be used to mine minerals from the soil. The process is called phytomining. A company in this line of work thought it could wrest a profit from Oregon’s countryside, so a decade ago Viridian Resources of Texas planted a “hyperaccumulating” species, expecting to harvest, dry, and smelt its leaves in order to extract nickel. Turns out, the project was not economically worthwhile, and now eradication of the Alyssum has become a financial liability. [Species used in phytoremediation may be any of the following: A. murale, A. pintodasilvae, A. malacitanum, A. lesbiacum, A. tenium, and A. fallacinum.] Read more here.
