Scented geraniums are something I have always used in the gardens. They are very easy to grow, pest free and require only moderate amount of water to thrive.
In the forefront of this picture is my only lemon scented geranium that grows in the drought tolerant street side garden in SJC. I planted it in this location mainly because of the color, a light yellow-green. It makes a nice contrast to the dark green reedy grass clump behind it and the soft bluish green senecio in front of it.
Unfortunately it is not the best location for enjoying its strong lemon scent that is released whenever the leaves are crushed because it is off the path far enough that it doesn't come in contact with anyone or thing to stimulate the scent it releases.
But another good trait is that it is easily propagated and so I am going to take some cuttings and start a few more plants to put in closer to a path that will allow for more interaction with this charming shrubby perennial.
