How it looks: Ferns are quite an interesting group of plants to grow indoors because of the various types of fronds they display, so you could have three ferns in one room from the same class and genera that look kind of unrelated.
The Bird's nest differs from many in appearance because of it's spear like shaped leaves rather than feather or palm like fronds. The leaves (have a brown mid-rib and wavy margin) grow up to about 2ft long from a rosette of fronds where new leaves appear when the plant is producing new growth.
Displaying: While a plant is young and small it can be placed anywhere in a home or office with the correct conditions provided (light, etc.). Once it matures though, you'll need to provide enough space for the rosette of fronds to spread out over 2ft each side. A conservatory is best suited or a fairly large room once it does mature.
Care level: The two main conditions to provide well is enough humidity and to protect the leaves from direct sunlight (they become scorched), although some sunlight is ideal for them. If a person has sufficient living space and can follow the straight forward care instructions below, anyone can grow and maintain them.
