It’s California Native Plant Week and I’m profiling a different California native each day that is on my particular wish list.  Today is a favorite, Blue-eyed grass.  

Western Blue-eyed grass, Sisyrinchium bellum

“Out of the clover & blue-eyed grass
He turned them into the river-lane;
One after another he let them pass,
Then fastened the meadow-bars again.”

Blue Eyed Grass, Sisyrinchium bellum is a primitive iris

Blue-eyed grass or Western blue-eyed grass, Sisyrinchium bellum, is native to California and other areas west of the Sierra Nevada. A perennial meadow wildflower related to the iris family, it hides among the other grasses until the clear blue flowers appear in April or May.

Blue-eyed grass can hide among other grasses before it blooms

It can be found growing wild on grassy hillsides and in meadows throughout the California foothills, but since the flowers close up on cloudy days, the plant is nearly impossible to find when it is growing alongside other grasses. In the garden, care should be taken to mark where the normally evergreen plant grows if it goes dormant because of cold or drought.

A six petaled flower blooms at the end of each stem

The flowers of Blue-eyed grass are about 3/4 to 1 inch wide

The flowers form at the ends of long branching iris-like stalks about the same height as the leaves giving it the grassy look. Each flower is up to an inch in diameter, with 3 petals and 3 sepals. Each has a dab of yellow at the center and is topped with a delicate yellow style.

It is said that it be propagated by seed, and that it self-sows. It can also be propagated by division of its rhizomes. It would be fun to try all these methods to grow more and more of these little gems.

The two clumps, in mid March, on a south facing slope may spread by self seeding

The two clumps on my south facing slope get excellent drainage and are out of range of any drip irrigation, sheltered under a buddleia. Hardy to at least 20 degrees in winter they go dormant and die back to the ground in my garden. Deer do not bother it.

Blue-eyed grass in mid April

A cloudy bright day is best for photographing blue-eyed grass in full bloom, mid April.

This year, I noticed that there are two small shoots from the parent and have marked them with sticks so I don’t pull them up when weeding.

The tipped flower buds will remind you of iris buds

There are other Sisyrinchiums I’d like to try, the yellow S. californicum, usually found closer to the coast of California, which likes more moisture may possibly survive here with summer water. In the garden these small treasures should be planted or transplanted to an area where they can be easily seen.

Flowers close up until they see the sun

In doing this post, I am somehow reminded of one of my favorite books, California Native Plants for the Garden, by Carol Bornstein, David Fross and Bart O’Brien. It profiles more than 500 best California native plants best for gardening in Mediterranean climates anywhere.

Note: It was difficult to photograph the Blue-eyed grass since my autofocus had a hard time pinpointing the tiny flowers in midair. I held an oak leaf in front of the flower, pressed the shutter halfway to set focus and then lowered the leaf to take the photos.
