It is unclear if this plant will become a tough foe, or if it will be easily controlled. A very pretty little plant in the Iris family, this species from South Africa is popping up along trails in California. We do not know if this plant will be much of a wildland offender, but it is worth keeping an eye on. The weedy genus Schinus has another species we might have to worry about. While Schinus polygamus is perhaps not quite as weedy as its sibling species, it may cause trouble in moist, warm areas.
Present records have it in California.
This grass has been discovered in North America for the first time. Infesting a site in Fort Ord, near Monterey California, we do not know what kind of threat this plant will pose. It occurs as a wildland invader in other countries, but it does not seem to form rapidly expanding populations. This grass has been spotted in small populations in a number of states. It is starting to increase its range.
