Selecting houseplants

  • Many houseplants, such as lemon trees, add fragrance to a room.
  • Place a lemon tree near a window in direct sunlight.
  • Gardenias have beautiful flowers and lovely fragrance. To thrive, gardenias need high humidity. Mist the plant frequently and set it on tray of pebbles, then fill tray with water.
  • Stephanotis and jasmine are vine houseplants that smell great and produce delicate flowers.
  • Rosemary can be trained to grow vertically, and then trimmed like a Christmas tree. Rosemary leaves have a wonderful aroma, and can be picked and used in cooking.
  • Paperwhites are part of the daffodil family and are very easy to grow.
  • When repotting paperwhites, use a shallow dish with no drainage holes.
  • Partially fill the dish with gravel or marbles.
  • Press the paperwhite bulbs partway into the gravel, then add water until it just touches the bottom of the bulbs.
  • Place the dish in a cool location (50 to 60-degrees F) until you see new growth, then move it to a warmer spot. Flowers will bloom in four to six weeks.
  • Plant individual paperwhite bulbs in a small vase; don’t set the bulb directly in water.
  • Houseplants, through a process called translocation, can help clean the air of toxins and pollutants.
  • The eureka palm, lady palm, rubber tree, and peace lily are excellent air purifiers.
  • One large houseplant can clean the air in a 100-square-foot area.
  • In lowlight areas, consider growing mother-in-law’s tongue or any plant in the dracena family.
  • Zamioculcas Zamifolia, commonly called the ZZ plant, tolerates very little light and requires very little water.
  • Edible houseplants include sage, mint, basil, oregano, rosemary and thyme.
  • Remove herb plants from plastic containers and repot them into clay pots.
