Neelakurinji (Strobilanthes kunthiana)

Neelakurinji is Strobilanthes kunthiana, the shrub that turns whole hillsides of the Nilgiris, Palanis and Munnar blue about once every twelve years. The Nilgiris, the “blue mountains”, are often said to take their name from it. It is a plant to see, not to pick or eat.

How to recognise Neelakurinji

It is a bushy shrub, usually knee- to shoulder-high, growing in dense stands in the grasslands above roughly 1,300 metres. The leaves are opposite, elliptic and toothed.

In a flowering year every plant in a population blooms together: pale blue to purple-blue, two-lipped tubular flowers in dense spikes. In off years the slopes look like ordinary green scrub.

The plants flower once, set seed and die, and the new generation then grows for about twelve years before flowering again. Botanists call this synchronised, once-in-a-lifetime pattern plietesial.

Many other Strobilanthes in the Western Ghats keep their own cycles, from a few years to sixteen. Not every blue kurinji bloom is this species.

Traditional use of Neelakurinji

Sangam poetry

Kurinji gives its name to one of the five landscapes of classical Tamil poetry, the mountain tinai, the setting of lovers’ union. The Paliyan people of the Palani hills are said to have reckoned age by its blooms.

Sangam literature and hill community tradition

Modern notes on Neelakurinji

Recent mass blooms in Munnar and the Palanis, including 2018, drew hundreds of thousands of visitors. The next large Munnar bloom is expected around 2030.

Beekeepers prize the rare kurinji honey produced in a bloom year.

Neelakurinji safety

Stay on paths during a bloom. Trampling and picking damage the plants at the one moment they set seed.

Ecology and sourcing

It belongs to the shola–grassland mosaic of the high Western Ghats. Tea, eucalyptus and wattle plantations have replaced much of that grassland.

Kerala created the Kurinjimala Sanctuary in 2006 to protect a core habitat. Because each generation takes twelve years, a population lost to fire or clearance takes a very long time to come back.
