These plants grow like crazy as houseplants. They’re part of the geranium family and you can get them at WalMart for $5 per plant. Unfortunately they do not repel mosquitoes - this is a marketing fallacy. They’ve actually been photographed with mosquitoes lighting on the leaves. They do have a pleasant aroma though - gently citrusy. Just be prepared to stake them in large pots, as they make jungle-like growth, and quickly.
