I love native grasses.  I have several areas in my small yard set up with native grasses, not all of them bloom, however.  Some are just grass.  Some are rust colored year 'round (like rooster grass) and some are green until they go dormant, they never go through an autumn colored stage.

Here's some good info about how to care for them, how to cut back plants for wintering over, how and when to create new clumps for transplanting, etc.

I hope whoever buys this house, when it no longer works for us, will appreciate the work that went into the yard.
