Strobilanthes kunthiana

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.

[2][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,[3] 1982, 1994, 2006,[4] 2018 and 2022, these have no match to Solar cycles.

[6] The kurinji plant belongs to the genus Strobilanthes which was first scientifically described by Christian Gottfried Daniel Nees von Esenbeck in the 19th century.

Neelakurinji also bloomed in Chandra Drona Hill Ranges (Bababudan Giri) in Chikkamagaluru district of Karnataka in 2006.

[15] Kurinjimala Sanctuary protects the kurinji in approximately 32 km2 core habitat in Kottakamboor and Vattavada villages in Idukki district of Kerala.

The historical novel, Kurinji Flowers by Clare Flynn features the neelakurinji as a backdrop to a tragic love affair in 1940s India.
