The fiddle-leaf fig (Ficus lyrata) is a perfect indoor specimen plant. The plant features very large, heavily veined, violin-shaped leaves that grow upright on a tall plant. These plants are native to the tropics, where they thrive in very warm and wet conditions. This makes them somewhat more challenging for the home grower, who is likely to have trouble duplicating these steamy conditions. However, they are relatively tough plants also that can withstand less-than-perfect conditions for a fairly long time.
