Locally known as Neelakurinji

Neelakurinji (Strobilanthes kunthiana) is a shrub that is found in the shola forests of the Western Ghats in South India. Nilgiri Hills, which literally means the blue mountains, got their name from the purplish blue flowers of Neelakurinji that blossoms gregariously only once in 12 years. Paliyan tribal people apparently used it to calculate their age.[1]

This plant belongs to the genus Strobilanthes which was first scientifically described by Christian Gottfried Daniel Nees von Esenbeck in the 19th century. The genus has around 250 species, of which at least 46 are found in India. Most of these species show an unusual flowering behavior, varying from annual to 16-year blooming cycles.[2]

Plants that bloom at long intervals like Strobilanthes kunthiana are known as plietesials. Other commonly used expressions or terms which apply to part or all of the plietesial life history include gregarious flowering, mast seeding and supra-annual synchronized semelparity (semelparity = monocarpy).[3]


It occurs at an altitude of 1300 to 2400 metres. The plant is usually 30 to 60 cm high. They can, however, grow well beyond 180 cm under congenial conditions.[4]


Some species of Strobilanthes including this one are examples of a mass seeding phenomenon termed as masting[5] which can be defined as "synchronous production of seed at long intervals by a population of plants".[6] Strict masting only occurs in species that are monocarpic (or semelparous) -- individuals of the species only reproduce once during their lifetime, then die,[7] as is the case with Strobilanthes kunthiana.


They once used to cover the Nilgiri Hills and Palani Hills like a carpet during its flowering season. Now plantations and dwellings occupy much of their habitat. Besides the Western Ghats, Neelakurinji is also seen in the Shevroys in the Eastern Ghats, some parts of Idukki and sandur hills of Bellary district in Karnataka. In 2006, Neelakurunji flowered again in Kerala and Tamil Nadu after a gap of 12 years. .


Kurinjimala Sanctuary protects the kurinji in approximately 32 km² core habitat in Kottakamboor and Vattavada villages in Idukki district of Kerala, The Save Kurinji Campaign Council organizes campaigns and, programs for conservation of the Kurinji plant and its habit.[4] Kurinji Andavar temple located in Kodaikanal on Tamil Nadu dedicated to Hindu God Kartikeya also preserves Strobilanthes plants. The story of Karthikeya is nothing connected with Strobilanthes, it was a later addition[citation needed]. The God associated with Kurinji Malai or Strobilanthes hill is Kurinji Andavan, an ancient deity of tribes of Palni hills. Later mainstream Hindus took over the temple and interwoven story of Karthikeya with Kurinji Andavan[citation needed].

References in literature[edit]

Kurinji flower is used to describe the associated mountainous landscape where it blooms in classical Tamil literature. The famous poetic fragment "Red Earth and Pouring Rain" from Tamil literary piece Kuruntokai makes an indirect reference to the flower. The historical novel, Kurinji Flowers by Clare Flynn features the neelakurinji as a backdrop to a tragic love affair in 1940s India.
