Strobilanthes kunthiana, known as Kurinji or Neelakurinji in Tamil language and Malayalam and Gurige in Kannada, is a shrub of the bear's breeches family (Acanthaceae) that is found in the shola forests of the Western Ghats in Kerala, Karnataka and Tamil Nadu. The purplish blue flower blossoms only once in 12 years, and gave the Nilgiri Mountains range its name as nil (blue) + giri (mountains). The name Neelakurinji originates from the Malayalam language neela (blue) + kurinji (flower).^[1]^{[better source needed]} 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,^[2] 1982, 1994, 2006^[3] and 2018, these have no match to Solar cycles.

The Paliyan tribal people living in Tamil Nadu used it as a reference to calculate their age.^[4] This plant flowers during September–October.
