  Bathrooms are often overlooked as potential plant habitats, but the additional humidity--especially in winter--and the low light create the ideal conditions for semi-tropical houseplants. Bathrooms are a perfect place for low-maintenance houseplants.
  
  

Spider Plant

• Spider plants are low-maintenance plants that can be grown in almost any room in the home. Because they like bright but indirect light, and temperatures between 65 and 80 degrees Fahrenheit, the bathroom may be the perfect room for this popular houseplant. Set a spider plant next to the tub or hang one in front of the window. Be careful not to over water or over fertilize your spider plants. To avoid the brown tips that plague so many spider plants, give them purified water instead of tap water. Root new plantlets by detaching them and sticking them in water, then plant in a pot.
  
  

Cast Iron Plant

• This plant is a member of the lily family, but its flowers are a lot less showy; they are small (about 1 inch in diameter), brownish purple, appear just above the soil and are obscured by the leaves. This is the perfect plant for people who think they can't take care of houseplants, as it tolerates very low light and irregular watering. The leaves can grow upwards of 2 feet tall so make sure you have the space if you choose to grow it in your bathroom, although there is a dwarf variety called Minor.
  
  

Asparagus Fern

• Asparagus fern likes bright, indirect light--from the north, east or west--and evenly moist soil. Water this fern less in winter and always water it with warm water. If possible, place the pot on a shallow tray filled with pebbles and water to maintain constant humidity. This plant will grow well in a hanging basket.
  
  

Gardenia

• Gardenias are finicky plants that need the right temperatures and humidity in order to reward their grower with those splendid, luscious scented blooms. These plants need full sun and love high humidity, but avoid misting the leaves to achieve that humidity, as it could cause foliar fungal diseases; instead, set the pots on a pebble tray and keep it filled with water. Low humidity and insufficient light can cause the buds to drop just before opening, according to the University of Rhode Island, and a gardenia may not set buds if the conditions are too warm. The bathroom may be the perfect environment for gardenias in the home because of the humidity.
