Although the exact answer to why the Nilgiris, a part of the Western Ghats, is called 'Nilgiri' is not known, after 12 years, the Nilgiris really turn blue. Let us know some information about this.
Nilgiris are one of the major tourist attractions. About 32 square kilometers of the Nilgiris are covered with blue flowers once every 12 years. This flower blooms only once in 12 years.

The entire hilly valley of Nilgiris is filled with blue Nilkurinji flowers. Nilkurinji is a herbaceous plant found in Tamil Nadu, Karnataka and Kerala.
When Nilkurinji flowers bloom, the number of bees in the vast area of Nilgiris increases many times. According to botanists and geologists, one of the reasons is the sweet smell of indigo and the abundance of honey in the flowers.
This flower blooms mainly from July to November. In 2006, Nilgiris was covered with such blue indigo flowers.
In 2017, the vast area of Nilgiris will once again be covered with Nilkurinji flowers. That is why Nilgiri has taken place in the travel plans of many tourists next year.
