One of the best known and utilized native grass selections in Southern California, this beautiful, blue gray foliage spreads out 3'-4' or more. It will reach a height of 2'-3'. It rarely flowers. It does spread by rhizomes although not as vigorously as some closely related species. It can be extremely drought tolerant and care must be taken not to over water this species as it can rot from the center. Otherwise, it is carefree and requires virtually no maintenance.

This is one of the toughest plants, with a coarse appearance. It needs full sun and well drained sites.

Permeable Surfaces

If you have impermeable paving that you would like to make permeable, there are two main methods for doing so:
1. Break up hard paved surfaces to create spaces for water to seep through.
2. Remove and replace the surfaces with permeable paving.
