I've had great success with Peppermint and Aloe vera. Both plants are useful, can take a lot of abuse, and doesn't require any green fingers on your part. - Peppermint can be used to make tea, mojito, as flavour for ice cream, or you can just chew on the leaves as a snack. - Aloe vera juice can be used to relieve itching from sunburn or insect bites. - Need more plants? Just break off a bit of your old aloe vera or peppermint and shove it in some wet soil. - And of course, both plants are decorative. :)
