Trisetum

The trisetums are tufted perennial grasses (rarely annuals) with flat leaves and loose panicles.

The species of trisetum found in the Western States have similar palatability and are all fairly good to good forage, although somewhat less palatable to sheep than to cattle and horses.

Of the five trisetums in California only two species — nodding trisetum and spike trisetum — are abundant enough to be important forage producers.
