Mint is a rapidly growing perennial plant with various varieties that can grow to 3 feet tall and overgrow an area quickly. So you may want to contain mint in a pot or use an underground container since mint spreads by using underground rhizome runners.
Also a part of the mint species, the lemon balm plant works to repel insects and attract others that can be beneficial. But unlike mint, it will not spread aggressively.
Citronella is an evergreen plant that grows well in climate zones 9-11. It is not a good choice if you are in a colder climate because it doesn’t do well indoors.
