Grass Widow (Olsynium douglassii>) is an early-blooming, perennial plant of open woodlands and rocky meadows that are wet in early spring but later dry up.

The satiny, reddish-purple to pinkish-purple flowers are up to about 1.5 in (4 cm) across and the whole plant is less than 12 in (30 cm) tall.

Hundreds of these purple flowers can cover a meadow, creating a beautiful scene as they shimmer in the breeze.

Other common names for this plant are Satin Flower and Douglas’ Blue-Eyed Grass. It has also had a different genus: Sisyrinchium

The species name douglasii honors David Douglas, a botanist who was an early explorer of the Pacific Northwest. You might have heard of Douglas Fir? Well, that was another plant named after David Douglas.

Grass Widow is in the iris family, Iridaceae, which includes only a handful of species in our region. One that is probably familiar to many northwesterners is Oregon Iris(Iris tenax).
