Black Mondo Grass

I've had this plant for a while, the green is new growth, this plant is in need of some major dividing.

The blooms are so pretty but they only last a week or two.

This plant I divided about three years ago, it has finally bloomed. No wonder this stuff is so expensive...

I keep this perennial grass in containers under the canopy of an old deciduous oak tree on our north-facing patio.
