  • India is home to about 230 species of balsams with 2 balsam hotspots of the world namely
  • Eastern Himalayas
  • Western Ghats.

  • In Western Ghats it is mainly concentrated in Shola Forests of Silent Valley National Park, Nilgiris in Kerala.


  • Balsam species are highly endemic and restricted to limited areas.
  • They are called Impatiens because when pressed the curled up flowers throw up the seeds violently.
  • Balsams being angiosperms are known for bright-coloured flowers and thus are important horticulture species.
  • Being highly endemic, they are climate-sensitive species.


  • Balsams grow in rich moist soil.
  • Thus they are confined to wet rocks of evergreen forests, waterfalls, roadside drains, banks of rivers etc.
  • They grow best at altitudes of about 550m.
  • Due to its climate-sensitivity, balsams cannot withstand high temperatures and long exposure to sunlight.
