• Building an indoor garden using various plants and flowers is a simple, inexpensive way to add beauty to your home. Large floor plants play an essential part in the establishment of an appealing indoor garden. Place taller floor plants in corners of the area or use them as a centerpiece and add other smaller-sized plants around them. When building indoor gardens, select varieties of plants that have similar light and temperature requirements.
  
  

Areca Palm

• Commonly known as the golden cane palm, arecea palms (Chrysalidocarpus lutescens) may reach heights of 20 to 30 feet, but you can trim them to a smaller height when grown indoors. The acrea palm has two or more trunks, long, slender, spotted leaves that are bright green with a yellow tint. Keep soil slightly damp at all times and thrive when grown in humid conditions. Acrea palms will grow in both bright and low light but are most attractive in diffused light.

Diffenbachia

• The Diffenbachia (Diffenbachia amoena), also known as the dumb cane, is a tropical plant with oblong leaves that grow to 18 inches in length. The plant reaches a mature height of six feet used as an indoor floor plant.

This evergreen shrub reaches a height of 10 to 15 feet and produces a green, unappealing flower and a small orange berry.

Fishtail Palm

• The hardy, easy-to-grow fishtail palm (Caryota mitis) is an interesting addition to indoor gardens. Fishtail palms reach heights of 12 feet or more and have long, medium-green, fan-shaped fronds. The fishtail palm thrives in humid, warm conditions, in moist soil and where it receives at least 6 hours of strong light each day.

Skin irritation may occur when handling the berries.
