Strobilanthes kunthiana
Strobilanthes kunthiana, known as Kurinji or Neelakurinji in Tamil, is a shrub that is found in the shola forests of the Western Ghats in Kerala and Tamil Nadu. Nilgiri Hills, which literally means the blue mountains, got their name from the purplish blue flowers of Neelakurinji that blossoms only once in 12 years. Of all long interval bloomers (or plietesials) "Strobilanthes kunthiana" is the most rigorously demonstrated, with documented bloomings in 1838, 1850, 1862, 1874, 1886, 1898, 1910, 1922, 1934, 1946, 1958, 1970, 1982, 1994, 2006 and 2018, these have no match to Solar cycles.

Other "kurinji" species, such as "Strobilanthes cuspidatus", bloom once every seven years, and then die. Their seeds subsequently sprout and continue the cycle of life and death.

The Paliyan tribal people living in Tamil Nadu used it as a reference to calculate their age.
This plant flowers during September–October.
