Ficus -- Ficus sp.There are many species of ficus, but they all come with an important warning: Don't plant them in the ground unless you have a lot of property! They are best used as shade trees in large containers because of their aggressive growth and invasive roots. Indoors or out, neglect them without guilt. They do just fine in any soil, even in drought conditions. Just make sure your ficus gets adequate light; full shade is a no-no.
