Plants that don't flower are often grown for their leaves. Foliage plants are good as houseplants and for use in planters. Many times, depending on variety, they will help clean the air. Plants for foliage are good for those who want living plants indoors but don't want the dead flowers or falling blooms that they will have to clean up.
Chinese evergreen, Aglaonema modestum, is a perennial. It has dark green leaves that are marked with the colors white or silver. Leaves are pointed rather, than oval or elliptical. The plant has no fragrance. It is an easy to grow plant and should be grown in bright indirect light, low humidity and in moist, nutrient-rich soil. Temperatures should range from 60 to 85 degrees Fahrenheit (16 to 29 degrees Celsius) for the plant to thrive. Feed with a lime-free fertilizer that is water soluble every other week from spring to fall. Propagate via division, seeds or stem cuttings. This plant can remove toxins from the air. Check for mealy bug infestation, as it is prone to that pest.
Calico Plant, Alternanthera bettzickiana, is a trailing perennial. It has olive green leaves that are tinged with a red color, and the plant has some fragrance. It should be grown in full sun, medium humidity and moist, nutrient-rich soil. This plant grows best in temperatures from 60 to 85 degrees Fahrenheit (16 to 29 degrees Celsius). Feed with a water-soluble fertilizer every other week, and propagate via stem cuttings or by division. It is not prone to pests or disease.
Giant Elephant Fern
Giant elephant fern, Angiopteris evecta, is also known as a king fern or a mules foot fern. The foliage is fleshy, and it has a large base.

Feed every two weeks from the spring to the fall with a water-soluble fertilizer that is diluted 50 percent. Propagate via spores, and check the plant for aphids, mealy bugs or scale, as it is prone to these three pests and diseases.
Monkey Puzzle Tree
