There are several species of thistle that are weeds in New Zealand; Nodding Thistle, California Thistle, Scotch Thistle and Sow Thistle. Californian Thistle is a perennial and can be difficult to control due to vegetative growth from its creeping and spreading root system. In mown lawns it produces flat low leaves in a rosette. As the leaves are prickly they can make walking barefoot on the lawn a painful experience.
