Ficus mac. 'Alii' - standard (Long-Leaf Fig)The Ficus alii (Ficus maclellandii Alii) is most commonly known as the Banana Leaf Fig because of its long, narrow leaves. The plant is known for its large, dark green, shaggy leaves that come down on its sides. These can grow to between 3 and 10 inches long making them look like willows. Because of its size (up to 10 feet high in containers), it makes for a great accent piece in living rooms and even patios.
