Identification

• Common geraniums are annual flowers that are a member of the genus Pelargonium, while "true" geraniums include perennials and wildflowers that are members of the genus Geranium.
  
  

Features

• Geraniums vary in leaf, flower and growth habit. They also have a wide range of vibrant colors and attractive leaves that make them indispensable plants to grow anywhere in the garden.
  
  

Considerations

• Geraniums require at least four hours of direct sunlight per day in order to produce healthy flowers, but they appreciate midday shade in overly hot climates. They grow best in well-drained, fertile soil, which should be allowed to dry between each watering. An application of mulch helps keep geraniums cool in summer.
