One is Citronella Grass and a scented geranium known as Citrosa or the mosquito plant. Both plants smell alike and have a similar name but other than this there is nothing similar about these plants.
Citronella Grass is an inedible grass this grass is closely related to lemongrass. It is the primary source of citronella oil an essential oil used widely as a nontoxic mosquito replant. It is also used in different cuisines. Citronella geraniums, on the other hand, smells a lot like Citronella Grass but does not contain the oil.

How to grow citronella plant from cutting?
To put things into perspective this article will deal with the mosquito repellent grass or the Citronella geraniums. These plants have a lemony scent and are bought as saplings. They are available across the US in garden centers as small plants.
Most gardeners get these as a starter and then propagate citronella plant. They are not the type that is grown from seed. These plants are generally propagated from stem cuttings. Here is a step-to-step guide on how to grow citronella plant from cutting and on how it’s done.
Step-1: procuring cuttings
In order to propagate citronella plant, you will require a cutting from the parent plant. To get a cutting you first need to sterilize your scissors or pruners. You also need to make sure that the scissors are sharp. Blunt instruments will damage the parent plant. You are looking to make a cut as clean as possible.
While looking for a cutting for propagation it is important to get at least two nodes. Nodes are the bumps on the stems and branches where the leaves emerge from.
The reason you require two nodes is cos you will need to have one node under the surface of the soil or water while planting it. The other will remain above the ground it is from here that new leaves and shoots will emerge from.
Step-2: Leaves removal
Once you have a good enough cutting you will need to make sure that all the leaves are taken off. Too much greenery on the cutting will drain the moisture which is required for the rooting process. If the cutting dries out before the roots form you will not be able to use the cutting.
You can leave just a leaf or two on the cutting provided they are small. If there are bigger leaves trim them to three fourth the size and leave them be.
Tip: you are looking for leaves of the size of a bottle cap
Step-3: application of rooting agent
When you are dealing with cuttings the use of a good rooting agent becomes imperative. Rooting compounds are not very expensive and you can get a jar and use it as and when required. There are also homemade rooting agents that can be used to promote the rooting process.
Rooting agents or compounds are actually an externally introduced agent that contains naturally occurring hormones that stimulate root growth. If you are not a fan of rooting agents you can always stick the cutting in moist soil and wait a few weeks before it roots.
With the rooting agent, the process will be a little faster. You can use the rooting agent in both soil as well as water.
The citronella plant is fond of the sun. for these plants to grow well, you will require at least six hours of full sunlight every day. The best part about these plants is that they can survive outdoors all year through in USDA plant hardiness zones 9b through 11.
