Kurinji and the patience of flowers

In P Jeganathan’s photograph, pale purple flowers gather among ferns and tall grass. Cloud softens the hillside beyond them. The picture was taken in the Nilgiris on 27 August 2018, and its quiet detail offers a different starting point from the familiar promise of whole mountains turning blue.

Kurinji invites us to think about time as much as colour. Understanding the plant makes its flowering more interesting, while helping us read photographs, travel stories and future plans with a little more care.

Begin with the plant’s name

Neelakurinji is Strobilanthes kunthiana. Kew’s Plants of the World Online accepts this name, places the species in the Acanthaceae family and records its native range as south-western India. The botanical name matters because a flowering shrub described simply as “kurinji” deserves a closer identification.

The wider Strobilanthes group contains a considerable variety of plants. A 2024 study by K. Kiruthika, M. Sulaiman and C. Krishnaveni recorded twelve species in its Nilgiris survey, ten of them endemic to the Western Ghats. That is a finding from the study, rather than a complete count of every species in the district.

Its authors also emphasise that understanding flowering periodicity requires regular visits to particular sites. For a traveller, the useful lesson is to keep the name and location together. One photograph of purple flowers cannot establish that every kurinji plant, or every part of the hills, follows the same timetable.

Twelve years, one reproductive season

A 2008 study by Manju V. Sharma, Giby Kuriakose and Kundaranahalli R. Shivanna describes neelakurinji’s synchronised flowering and mass seed production on a twelve-year cycle.

The researchers call it semelparous: the plant has one reproductive occasion in its lifetime. The familiar phrase “flowers every twelve years” can therefore be misleading if it suggests the same shrub repeatedly putting on a display. Flowering and seed production belong to a generational cycle; the parent plant dies after reproducing.

This changes the story behind the colour. A mass bloom is a concentrated stage in the lives of many plants, with the next generation depending on successful reproduction. The years between flowering are part of that life history too.

The small movements behind the spectacle

The same researchers identified the honeybee Apis cerana indica as the principal pollinator in their study. They also observed a striking detail: the flower’s pollen-receiving surface, the stigma, responds to a visiting bee by bending away after contact.

That movement helps manage pollen transfer as the bee enters and leaves. It is a reminder that a hillside display is made up of individual flowers, each with its own intricate working parts.

The photograph cannot show all of this. Yet knowing about it changes where attention might settle: from a distant sweep of colour to the shape of a flower and the movement of an insect. There is much to notice without touching the plant.

Read the date as well as the colour

The accompanying image is an archive photograph from 2018. It records a flowering moment in the Nilgiris; it does not establish what is blooming now. The distinction is useful whenever an old image returns in a new travel story.

Before planning around a reported bloom, look for a recent observation, an identified plant and a named location. Confirm permitted access with the relevant land manager or Forest Department before setting out. A flowering report alone is not permission to enter a hillside, and this article does not identify a currently open bloom-viewing site.

When flowers can be viewed from an authorised route, leave them rooted and keep to the route. A photograph need not require stepping into a patch or pulling a branch towards the lens.

Kurinji’s long rhythm offers another way of looking at the hills around Ooty. A flowering season is remarkable, but so is the patient work of understanding it: naming the plant, recording the place and date, and allowing the next stage of its life to continue.
