Blue-Eyed Grass: The Charming Native That’s Not Actually Grass

Despite its common name, blue-eyed grass (Sisyrinchium) isn’t a grass at all – it’s actually a member of the iris family! This delightful native plant has been fooling gardeners with its grass-like appearance for years, but once you see those tiny, star-shaped flowers, you’ll understand why it deserves a special place in your garden.

What Makes Blue-Eyed Grass Special?

Blue-eyed grass is a charming forb that produces clumps of narrow, iris-like leaves topped with small but stunning flowers. These delicate blooms typically come in shades of blue, purple, white, or yellow, each with a bright yellow center that gives the plant its blue-eyed nickname. The flowers are small – usually less than an inch across – but they make up for their size with their abundance and delicate beauty.

As a perennial (though some species can be annual), blue-eyed grass forms neat, grass-like tufts that rarely exceed 12 inches in height. Don’t let the modest stature fool you – this little plant packs a big punch in the garden!

Where Blue-Eyed Grass Calls Home

This native gem has an impressive range across North America. Sisyrinchium species are native to Alaska, Canada, Greenland, Puerto Rico, and St. Pierre and Miquelon. You’ll find various species growing naturally across an extensive geographic distribution, including most U.S. states from Alabama to Wyoming, Canadian provinces from Alberta to Yukon, and territories from Northwest Territories to Newfoundland and Labrador.

• Self-seeding: Allow some flowers to go to seed for natural propagation

A Few Things to Consider

While blue-eyed grass is generally wonderful, there are a few things to keep in mind:

• Individual flowers are short-lived (lasting only a day), though new ones keep appearing
• Plants may go dormant in extreme heat or drought
• Some species can be aggressive self-seeders in ideal conditions
• The grass-like foliage may look sparse when not in bloom
