It is likely that you have heard of this one as it is one of the more common ingredients in many insect repellents. There are even candles made from it. However, what you may or may not know is that citronella is actually a plant. It is a perennial that looks like clumping grass.
This plant gives off a strong odor. This odor is stronger than any product you can buy with citronella in it, making it a great choice for your yard. The plant is easy to grow and can reach heights of up to five or six feet.
