The fiddle-leaf fig (Ficus lyrata) is a popular indoor specimen plant featuring very large, heavily veined, violin-shaped leaves that grow upright. These plants are native to tropical parts of Africa, where they thrive in very warm and wet conditions. This makes them somewhat challenging for the home grower, who is likely to have trouble duplicating these steamy conditions. However, they are relatively tough plants that can withstand a less-than-perfect environment for a fairly long time.Fiddle-leaf figs are perfect as focal points of a room if you can situate them in a floor-standing container where the plant is allowed to grow to at least 6 feet. (Most indoor specimens reach around 10 feet tall.) They’re fairly fast growers and can be potted at any point in the year if you're like most gardeners acquiring a nursery plant to keep indoors.
