Large indoor plants include tropical house plants such as peace lily and bird of paradise. Small trees, such as Norfolk Island pines, plumerias and indoor palm trees also adapt well to indoor conditions, as do fig plants. All of these plants can grow to more than 5 feet tall.
The peace lily is easy to grow. It likes shade and can purify the air. The bird of paradise, which is known for the beautiful blue and orange flowers it bears during the summer, is an evergreen with large leaves.
Norfolk Island pines, which are often available around the holidays, like indoor conditions. They are inexpensive to buy and can grow up to 20 feet tall.
Palm trees, which are often sold for indoor use, are easy to grow and thrive in low light conditions. Plumerias need lots of heat and humidity but bear beautiful, sweet-smelling flowers in the summer and fall.
Plants in the ficus family, such as figs, can become large and tree-like indoors. Rubber plants, fiddle leaf figs, Indian laurel and weeping figs flourish in homes. The glossy leaves of these plants are leathery, and some types are variegated. Fig trees grow rapidly, so the owner must plan ahead to provide enough space. Regular pruning keeps them under control.
