The Timeless Bloom: How Sri Lanka’s Horton Plains awaken every 12 Years

The Valley in Bloom

The air is crisp and thin atop Horton Plains, the morning mist curling like breath over the rolling patanas. Then, as the rising sun pierces the haze, the landscape begins to shimmer—waves of mauve and violet unfurl across the slopes, as though the earth itself has exhaled after a dozen years of silence. Bees hum in the stillness. A sambar deer lifts its head, framed by the purple blaze. After 12 long years, the Nilu has returned.

This is 2025, and Sri Lanka’s highlands are once again transformed by the mass flowering of Strobilanthes, locally called

Nilu.” It is an event so rare and rhythmic that few living people have witnessed it more than twice in their lifetime. For those who stand here today—among the rippling blossoms, where clouds cast fleeting shadows across mauve hillsides—it feels as though time itself blooms with the flowers.

Tracing the Bloom Through Time

I first stood amid this botanical tide in 2013, camera in hand, the Horton Plains veiled in violet light. Even then, I sensed that I was witnessing something larger than beauty—a heartbeat of the land, one that pulses only every 12 years. Digging deeper, I discovered that I was not alone in this fascination. In 1910, British planter and naturalist

Thomas Farr, who built the original Farr Bungalow” at Horton Plains, wrote of this same miracle in meticulous detail.

Farr documented the great flowerings of 1881, 1893, and 1905, and confidently predicted the next in 1917. His forecast proved astonishingly accurate. Since then, the blooms have recurred with unwavering regularity: 1929, 1941, 1953, 1965, 1977, 1989, 2001, 2013, and now—true to the century-long rhythm—2025.

During my own field visits, I uncovered fragments of local memory and tangible evidence: Mr. Perera of Ohiya spoke of the 2001 bloom with reverence, recalling how the hills turned purple overnight. My 2013 documentation added another link in the chain—a living continuation of Farr’s cycle, now spanning more than 140 years.

This year’s spectacle not only confirms Farr’s observations; it validates nature’s astonishing precision. Across the plateau, the Nilu has kept time better than any clock we could build.

The Plant That Waits a Dozen Years

The Nilu belongs to the genus Strobilanthes—a group of tropical shrubs and herbs known for a peculiar rhythm: synchronous, gregarious flowering followed by death. Botanists describe it as monocarpic, meaning each plant flowers only once in its lifetime. For 12 years, these unassuming green bushes quietly photosynthesize, storing energy for one single, all-consuming act of reproduction. Then, in a matter of weeks, they burst into bloom, release millions of seeds, and die—blanketing the forest floor in their faded remains.

Among Horton Plains’ many species,

Strobilanthes sexennis stands tall, reaching up to 30 feet, its mauve blossoms painting the valleys in ethereal tones.

The pink-flowered

S. pulcherrimus and pale S. viscosus join the chorus, blending hues of heliotrope, lilac, and white. Together, they transform the undergrowth into a living tapestry, what Farr once described as like fairy lands, as though veils of transparent gauze were draped through and about the Nilu stems.”

Echoes of 1910: When Nature Moved as One

Farr’s century-old prose captures the ecological choreography of this phenomenon with astonishing acuity. In his 1910 essay The Inflorescence of the Nilu (Strobilanthes), he wrote of Bambara bees swarming from the lowlands, drawn by instinct and the scent of nectar. He observed elephants retreating from the stinging clouds of bees,

sambar deer returning to graze the newly opened glades, and leopards following in their wake. Even jungle-fowl and pigeons, Farr noted, migrated toward the flowering zones to feast on the bounty of seeds—a trek,” he called it, that rippled through the web of life.

Today, many of those players remain—though elephants no longer roam these uplands. Modern ecology now explains what Farr could only marvel at: the Nilu flowering acts as a trophic pulse, a sudden surge of energy cascading through the ecosystem. The explosion of nectar feeds pollinators; the seed rain sustains rodents and birds; predators thrive on the abundance. Then, as the plants die, sunlight reaches the soil, allowing a new generation to sprout—a cycle of death and renewal, written in the DNA of the hills.

Nature

s Calendar

The regularity of this rhythm—every 12 years without fail—is one of nature’s most exquisite mysteries. The timeline now reads like a biological chronicle of Sri Lanka’s highlands:

1881, 1893, 1905, 1917, 1929, 1941, 1953, 1965, 1977, 1989, 2001, 2013, 2025.

Each date marks not just a flowering, but a fleeting convergence—of generations, species, and human witnesses. Farr saw the first three. I have seen the last two. The next, in 2037, will bloom for another generation—perhaps observed by those who read these words today.

Kin Across the Sea

Across the Palk Strait, in India’s Western Ghats, the famed Neelakurinji (Strobilanthes kunthiana) follows the same 12-year rhythm, cloaking the Nilgiri Hills in lavender-blue. To gether, these cousins tell a story that transcends borders: of evolutionary adaptation, of resilience in montane habitats, and of the quiet synchrony that unites distant ecosystems across time.

A Bloom Worth Protecting

As throngs of visitors now trek to Horton Plains to witness the Nilu, the challenge lies in balancing wonder with responsibility. Overcrowding, trampling, and litter threaten the very ecosystems that nurture this miracle. Scientists warn that climate change—altering rainfall, temperature, and pollinator behaviour—could disrupt the Nilu’s inner clock. If so, the 2037 bloom might not come on schedule.

The Nilu is more than a tourist attraction; it is a living clock of climate, a barometer of ecological health. Protecting its rhythm means safeguarding the integrity of Horton Plains itself—its soils, forests, pollinators, and every invisible thread that ties them together.

The Long Patience of the Hills

Standing here in 2025, surrounded by the mauve sea of blossoms, I think of Farr in 1910, penning his notes by lamplight at the old Farr Bungalow. I imagine his bees swarming, his deer returning, his awe no different from mine. Between us stretch 144 years—yet the same bloom, the same rhythm, the same pulse.

The Nilu teaches patience. It reminds us that some miracles unfold not in days, but in decades—that the earth keeps its own calendar, immune to human haste. To witness it is to step briefly into nature’s time, where 12 years are but a breath, and beauty, like memory, always returns.

As the mauve hills fade back to green, and another 12-year silence begins, one can only hope that when the Nilu blooms again in 2037, the world will still be listening.

Fractious West facing a more solidified Eastern opposition

Published

on

Going forward, it is hoped that a reported ceasefire agreement between the US and Iran would provide a basis for a degree of stability in the Middle East and pave the way for substantive peace talks between the powers concerned. The world is compelled to fall back on hope because there is never knowing when President Donald Trump would change his mind and plans on matters of the first importance. So erratic has he been.

Yet, confusion abounds on who has agreed to what. The US President is on record that a number of conditions put forward by him to Iran to deescalate tensions have been accepted by the latter, whereas Iran is yet to state unambiguously that this is so. For instance, the US side claims that Iran has come clear on the point that it would not work towards acquiring a nuclear weapons capability, but there is no official confirmation by Iran that this is so. The same goes for the rest of the conditions.

Accordingly, the peace process between the US and Iran, if such a thing solidly exists, could be said to be mired in uncertainty. Nevertheless, the wider publics of the world are bound to welcome the prospects of some sort of ceasing of hostilities because it would have the effect of improving their economic and material well being which is today under a cloud.

However, questions of the first magnitude would continue to bedevil international politics and provide the breeding ground for continued tensions between East and West. Iran-US hostilities helped highlight some of these divisive issues and a deescalation of these tensions would not inevitably translate into even a temporary resolution of these questions. The world community would have no choice but to take them up and work towards comprehending them better and managing them more effectively.

For example, there are thorny questions arising from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Essentially, this treaty bans the processing and use of nuclear weapons by states but some of the foremost powers are not signatories to it.

Moreover, the NPT does not provide for the destroying of nuclear arsenals by those signatory states which are already in possession of these WMDs. Consequently, there would be a glaring power imbalance between the latter nuclear-armed states and others which possess only conventional weapons.

Such a situation has grave implications for Iran’s security, for instance. The latter could argue, in view of the NPT restrictions, that the US poses a security threat to it but that it is debarred by the Treaty from developing a nuclear arms capability of its own to enable it to match the nuclear capability of the US. Moreover, its regional rival Israel is believed to possess a nuclear weapons capability.

Accordingly, a case could be made that the NPT is inherently unfair. The US would need to help resolve this vexatious matter going forward. But if it remains, US-Iran tensions would not prove easy to resolve. The same goes for Iran-Israeli tensions. Consequently, the Middle East would remain the proverbial ‘powder keg’.

Besides the above issues, the world has ample evidence that it could no longer speak in terms of a united NATO or West. Apparently, there could be no guarantee that US-NATO relations would remain untroubled in future, even if the current Iran-US standoff is peacefully resolved. US-NATO ties almost reached breaking point in the current crisis when the US President called on its NATO partners, particularly Britain, to help keep open the Hormuz Straits for easy navigation by commercial vessels, militarily, on seeing that such help was not forthcoming. Such questions are bound to remain sore points in intra-Western ties.

In other words, it would be imperative for the US’ NATO partners to help pull the US’ ‘chestnuts out of the fire’ going ahead. The question is, would NATO be willing to thus toe the US line even at the cost of its best interests.

For the West, these fractious issues are coming to the fore at a most unpropitious moment. The reality that could faze the West at present is the strong opposition shown to its efforts to bolster its power and influence by China and Russia. Right through the present crisis, the latter have stood by Iran, materially and morally. For instance, the most recent Security Council resolution spearheaded by the US which was strongly critical of Iran, was vetoed by China and Russia.

Accordingly, we have in the latter developments some marked polarities in international politics that could stand in the way of the West advancing its interests unchallenged. They point to progressively intensifying East-West tensions in international relations in the absence of consensuality.

It is only to be expected that given the substance of international politics that the West would be opposed by the East, read China and Russia, in any of the former’s efforts to advance its self interests unilaterally in ways that could be seen as illegitimate, but what is sorely needed at present is consensuality among the foremost powers if the world is to be ‘a less dangerous place to live in.’ Minus a focus on the latter, it would be a ‘no-win’ situation for all concerned.

It would be central to world stability for International Law to be upheld by all states and international actors. Military intervention by major powers in the internal affairs of other countries remains a principal cause of international mayhem. Both East and West are obliged to abide scrupulously with this principle.

From the latter viewpoint, not only did the West err in recent times, but the East did so as well. Iran, for instance, acted in gross violation of International Law when it attacked neighbouring Gulf states which are seen as US allies. Neither Iran nor the US-Israel combine have helped in advancing international law and order by thus taking the law into their own hands.

Unfortunately, the UN has been a passive spectator to these disruptive developments. It needs to play a more robust role in promoting world peace and in furthering consensual understanding among the principal powers in particular. The need is also urgent to advance UN reform and render the UN a vital instrument in furthering world peace. The East and West need to think alike and quickly on this urgent undertaking.

Science-driven health policies key to tackling emerging challenges — UNFPA

Published

on

Dr. Dayanath Ranatunga

Marking World Health Day on April 7, health experts have called for a stronger commitment to science-based decision-making to address increasingly complex and evolving health challenges in Sri Lanka and beyond.

Dr. Dayanath Ranatunga, Assistant Representative of the United Nations Population Fund, stressed that health is no longer confined to hospitals or traditional medical systems, but is shaped by a broad spectrum of social, environmental, and technological factors.

“This year’s theme, ‘Together for Health. Stand with Science,’ reminds us that science is not only for laboratories or policymakers. It is a way of thinking and a tool that shapes everyday decisions,” he said.

Dr. Ranatunga noted that modern health challenges are increasingly interconnected, ranging from infectious diseases such as COVID-19 to climate-related risks, demographic shifts, and emerging forms of online violence.

He warned that maternal and newborn health continues to demand urgent attention despite progress. Globally, an estimated 260,000 women died from pregnancy and childbirth-related causes in 2023 alone—many of them preventable through timely, science-based interventions.

“In countries like Sri Lanka, where fertility rates are declining and survival rates improving, every pregnancy carries greater significance—not just for families, but for the future of communities and economies,” he said.

The UNFPA official also highlighted the growing threat of Technology Facilitated Gender-Based Violence (TFGBV), including cyber harassment and online abuse, noting that these forms of violence can have deep psychological consequences despite lacking visible physical harm.

He emphasised the need for multidisciplinary, science-informed approaches that integrate mental health, digital safety, and survivor-centered care.

Turning to demographic trends, Dr. Ranatunga pointed out that increasing life expectancy is bringing new challenges, particularly the rise of non-communicable diseases such as diabetes, cardiovascular illnesses, and cancers.

In Sri Lanka, nearly 13.9% of mothers develop diabetes during pregnancy, a trend attributed to obesity and unhealthy lifestyles, underscoring the urgent need for preventive healthcare strategies.

“Are we investing enough in prevention?” he asked, noting that early intervention and healthier lifestyles could significantly reduce long-term healthcare costs, especially in a country with a free public healthcare system.

He underscored the importance of data-driven policymaking, stating that scientific research and analytics enable governments to identify gaps, anticipate future needs, and allocate resources more effectively.

The UNFPA, he said, is already leveraging tools such as Geographic Information Systems (GIS) to improve access to maternal healthcare, including mapping travel times for pregnant women to reach health facilities.

Digital innovation is also transforming healthcare delivery, from telemedicine to real-time data systems, improving efficiency and ensuring continuity of care even during emergencies.

In Sri Lanka, partnerships between the government and development agencies are helping to modernise training institutions, including facilities in Batticaloa, equipping healthcare workers with both clinical and digital skills.

However, Dr. Ranatunga cautioned that technology alone is not a solution.

“It must be guided by evidence and grounded in equity,” he said, pointing out that women’s health remains significantly underfunded, with only about 7% of global healthcare research focusing on conditions specific to women.

He also drew attention to the growing health impacts of climate change, including extreme weather, food insecurity, and displacement, describing it as an emerging public health crisis.

“Health does not begin in hospitals. It is shaped by the environments we live in, the choices we make, and the systems we build,” he said.

Calling for renewed commitment, Dr. Ranatunga urged stakeholders to invest in prevention, embrace innovation, and ensure that science remains central to policy and practice.

“Science is not just about knowledge—it is about ensuring that everyone has the opportunity to live healthy, dignified lives, and that no one is left behind,” he added.
