There are many great choices. Two of my favorites are the dwarf types of Miscanthus and the Fountain Grasses (Pennisetum). Check out the following web site. It will allow you to search for Monrovia plants. Select "grasses" in the "Search by" box and "7" in the "Your cold zone" box.
When a list of options is returned via the search, you can click on a plant to learn more about it and in many cases to see a photo too.
Thanks for the question. Please stop in again soon!
