Plant ID please

[indigo]

Hi Everyone, long time

I could use some help ID-ing this little beauty please.  I've got as far as some sort of sisyrinchium?  My friend has a similar one but hers the flowers have rounded tips, mine has very definite pointed tips.  It's about 3 inches or so tall, flowers only last one day., bluey green leaves.  I was expecting an iris as I watched it grow but was wrong...

Looks like Sisyrinchium, probably californicum? to me.

Thank you Chris   Googled images and yes, some of the pics are like mine, oddly though from google images, it seems there are at least two "types" of Sisyrinchium californicum, one with rounded petals and one with pointed.  There's also a taller variety.  As mine has just appeared this year, who knows what it's eventual height will be.

Could be there are either ssp or var names for them.  Someone here will know ....

We have Sisyrinchium c. brachypus as a nice 'weed' in the garden. I would have said that our brachypus grows slightly more erectly that that in the pictures but it could just be an age difference.
Yellow-Eyed Grass; or California Golden Blue-Eyed Grass; or, Yellow-Eyed Pigroot (alternative names from Paghat's Garden web site)!

Ah yes, S. brachypus, now I remember.  It spread everywhere, had to dig it all out in the end.... but it was useful in the space it took up while it lasted....
