Leaves and stem a similar pale-green with the stem being more linear than the leaves and with two wide wings either side of a very thin central 'stem' rather like a paper wire-wrap with a central wire down the centre.

Flowers a bright-yellow (not the pale yellow of the much taller Pale Yellow-Eyed Grass which has flowers in tight bunches up its stem). The green bracts near top are slightly pinched about an inch down and hide most of the flower stalk (petiole) and the stalks of the fruits. The sepal tube is quite narrow and lacks teeth. A fruit on the left stands almost upright.

Flower stalk paper-thin side-ways on. Glaucous-green bracts are arrow-head shaped and hide the flower and fruit stalks. Fruit larger than the sepal tube (hiding behind the fruit). Petals do not have a noticeable cuspidate end like those of Blue-eyed Grass and American Blue-eyed-grass

Three stamens as usual for Iris Family of plants. Anthers orange atop the filament like a 'T-bar'.

Fruits in 3 sections where they eventually split apart.


The Sisyrinchium (Blue-eyed Grasses) genus should not to be semantically confused with the similar sounding Genus Sisymbrium [Rockets].

Not to be semantically confused with Black-Eyed Susan (Rudbeckia hirta) a yellow flower belonging to the Dandelion & Daisy Family (Asteraceae). Uniquely identifiable characteristics

Distinguishing Feature : as a Blue-eyed grass - it's yellowness!

Easily distinguished from the much taller Pale Yellow-Eyed Grass which has pale yellow flowers which are in lateral cymes (small bunches) up the stem, including a terminal cyme at the top.

More resemblance to both Blue-eyed Grass (Sisyrinchium bermudiana) and American Blue-eyed-grass (Sisyrinchium montanum) but both of these are blue (rather than bright yellow) and they both have pronounced cuspidate (tapering to a point) tepals (rather than barely perceptibly cuspidate of Yellow-eyed-grass).

No relation to : Grass [a plant with similar name].

An introduce-naturalised Neophyte, grown in gardens and which escapes, but is not as often found as the Blue-eyed Grasses. It is non-native rhizhomatous perennial grown as a garden plant which sometimes escapes into the wild. It is native to the West Coast of North America.
