Growing exotic plants and flowers in your greenhouse is a terrific way to liven up your vegetation collection. Exotic plants grow well in a greenhouse because you can control the growing climate for each plant, adjusting the temperature, moisture, and sunlight exposure as needed. Their is an unending variety of species for you to choose from when selecing plants and flowers for your exotic collection.

Inexpensive passive solar greenhouses heated only by sunlight falling on 55-gallon barrels of water are effective for growing plants year-round, said a University of Missouri Extension specialist. Heat from sunlight is stored in water-filled barrels during the day and radiates at night, replacing use of fossil fuel, said Eric Lawman, an agronomy research specialist at the Bradford Research and Extension Center (BREC) near Columbia, Mo.
