Cayratia is a vine from the grape family that has been observed escaping in Texas and Louisiana, and it may be elsewhere in the Gulf Coast. 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.
