Plants can be used for many uses, and the Mosquito Plant, or Citrosa is a cross between the Grass of China ( which produces citronella) and a scented geranium which releases its scent into the air. This amazing feat was accomplished with gene splicing. The result is a scented geranium which grows rather large (up to 5 feet) and repels insects and is not only harmless to people, but has a pleasant citronella scent. The mosquito plant can be kept outdoors on patios or indoors as a houseplant. It can also be kept small by continual pinching.

This is an interesting plant that can be wintered over as a houseplant. There are just a few things to keep in mind:

1) give it as much light as possible. Avoid direct afternoon sun. If the new growth turns gray and soft, move it into more light.

2) Plant in large tubs or in the ground when you plant outside. Morning sun is OK, but just remember to keep it out of direct afternoon light. It should not go below 45 degrees

3) Keep soil on the dry side as too much water leads to rot.

4) Fertilize every two weeks with a good all-purpose feeder.

Remember that pinching new shoots will promote branching to shape the plant. Brushing lightly against other foliage will release more scent. It may take up to 24 hours to see results with insects.
