Sparkling, frilly edges

This is one of my favorite flowers on Bodega Head.  Do you want to guess which species this is?

It might be helpful to know where this species grows.  In this area, we find it along the coast, especially in salt marshes.

 

From a distance, the flowers of Seaside Arrow-grass (Triglochin maritima) might not stand out.  Up close, it's a different story.  Purple with sparkling, frilly edges — Oh, my!

P.S.  Usually Seaside Arrow-grass is tall and straight.  This Dr. Seuss-like version is somewhat unusual, but it was fun to see!
