An artificial turf has a base layer and a multiplicity of blades fixed to and projecting upward from the base layer. Each of the blades is formed of an elongated plastic filament having a longitudinally extending inner part of plastic and a longitudinally extending outer part bonded to the inner part and of a plastic different from the inner-part plastic. Both parts extend the full length of the respective blade.
