California Native Plant Society, September 2012. By Roger Klemm: Fountain Grass (Pennisetum setaceum) is a bunchgrass from Africa that is widely planted as an ornamental plant in portions of the United States with warm winters. It is a tough, vigorous plant that will tolerate adverse conditions of heat and drought. It does not appear to suffer from any pests or diseases, and many people appreciate its graceful seed heads produced in profusion over the spring and summer months.
The downside is that in California, Fountain Grass has no natural enemies and readily out-competes other plants. It is invasive, and if you plant it in your yard, you will soon have seedlings of Fountain Grass popping up wherever there is bare soil. It will even grow vigorously in the gaps between sections of concrete and bedrock of natural slopes. Its seeds are carried long distances in the wind, so if your neighbor has it in their yard, it will eventually end up in yours, and the nearby natural areas. If you are in a fire hazard area, it is especially dangerous, as it dries out early in the summer and becomes extremely flammable. Read More
