Gardeners' Notes:

Central Phoenix -- Being native to this area, deergrass does wonderfully in my garden. It is such a forgiving plant and fills a large area with its frothy yellowish-green mound. You can chop it to the ground and it comes right back. My only problem has been invasion by Bermuda grass, but I find it you cut the deergrass to the ground annually and carefully paint Roundup (I use a small foam paintbrush) on the Bermuda grass strands, it keeps it to a minimum.

Fast growing California bunch grass. It gets about 2 feet tall and the plumes are another two feet above that. It is quite spectacular. Can be grown as a specimen or multiples. Very low maintenance, only need to cut it back once a year before the new growth starts. Does not seem to be as demanding with respect to drainage as many other natives. Water efficient. This is a very good grass.
