Strobilanthes kunthiana (Wall. ex Nees) T. Anders. ex Benth. | |
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] 2018 and 2022, 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.
Kurinji grows at an altitude of 1300 meters to 2400 metres. The plant is usually 30 to 60 cm high. They can, however, grow well beyond 180 cm under congenial conditions. [5]
The kurinji 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. [6] [7]
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). [8]
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. [9]
Some species of Strobilanthes are examples of a mass seeding phenomenon termed as masting [10] which can be defined as "synchronous production of seed at long intervals by a population of plants". [11] Strict masting only occurs in species that are monocarpic (or semelparous) -- individuals of the species only reproduce once during their lifetime, then die, [12] as is the case with Strobilanthes kunthiana.
Kurinji once used to cover the Anamalai Hills, Cardamom Hills, Nilgiri Hills, Palani Hills, Kudremukh and Bababudangiri like a carpet during its flowering season. Now plantations and dwellings occupy much of their habitat. Neelakurinji also bloomed in Chandra Drona Hill Ranges (Bababudan Giri) in Chikkamagaluru district of Karnataka in 2006. The whole of Bababudangiri Hills (Datta Peeta) were covered in a carpet of bluish purple flowers. It is expected to bloom again in 2018 [13] Besides the Western Ghats, Neelakurinji is also seen in the Shevroy in the Eastern Ghats, Sanduru hills of Bellary district in Karnataka.
In 2006, Neelakurunji flowered again in Kerala and Tamil Nadu after a gap of 12 years.
In 2017, Neelakurinji flowers bloomed in the hills behind Kumaraswamy temple in Sanduru, Bellary district. [14]
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. [5] Kurinji Andavar temple located in Kodaikanal on Tamil Nadu dedicated to Tamil God Murugan also preserves Strobilanthes plants.
Kurinji flower is used to describe the associated mountainous landscape where it blooms in Sangam Literature classical Tamil literature. The historical novel, Kurinji Flowers by Clare Flynn features the neelakurinji as a backdrop to a tragic love affair in 1940s India. [15]
Prime Minister Narendra Modi also referenced the neelakurinji in his Independence Day speech in 2018, a year when the neelakurinji was in bloom. [16]

Sholas are the local name for patches of stunted tropical montane forest found in valleys amid rolling grassland in the higher montane regions of South India, largely in Kerala, Karnataka and Tamilnadu. These patches of shola forest are found mainly in the valleys and are usually separated from one another by undulating montane grassland. The shola and grassland together form the shola-grassland complex or mosaic. Not all such high-elevation grasslands have sholas in their valleys, especially if they are isolated from other such meadows, such as the meadows found in the Idamalayar Reserve Forest in Ernakulam district of Kerala. The word 'Shola' is probably derived from the Tamil language word cōlai (சோலை) meaning grove.
The Nilgiri Biosphere Reserve is a biosphere reserve in the Nilgiri Mountains of the Western Ghats in South India.

Monocarpic plants are those that flower and set seeds only once, and then die.
Plietesials are plants that grow for a number of years, flower gregariously (synchronously), set seed and then die. The length of the cycle can vary between 8 and 16 years. For example, the neelakurinji plant flowers every 12 years and bloomed as expected in 2006 and 2018 in the Munnar region of Kerala, India.

Karian Shola National Park is a protected area in the Western Ghats, India, nominated as a national park in 1989. The Western Ghats are a chain of mountains running down the west of India parallel with the coast some 30 to 50 km inland. They are not true mountains, but the edge of a fault that resulted about 150 million years ago as the subcontinent of India split from Gondwanaland. They are older than the Himalayan mountain range and are clothed in ancient forests. They influence the weather in India as they intercept the incoming monsoon storm systems. The greatest rainfall occurs between June and September during the southwest monsoon, with lesser amounts falling in the northeast monsoon between October and November. The Western Ghats are a UNESCO World Heritage Site and are considered to be one of the eight most important "hotspots" of biological diversity in the world.
