On my recent trip to Munnar (South India), I had the fortune to see the bloom of Neel Kurinji (blue-kurinji). It is a shrub like plant which blooms with a blue flower once in twelve years! If you want to experience the same, you will have to visit Munnar in 2018.
Some photographs for you –

Enjoy the pictures. Feel free to use them (and give me credit for the same!)
