Pink Daffodil 'Mrs R.O Blackhouse' on Brink of Extinction: RHS Urges Immediate Action to Preserve UK Botanical Heritage

A rare pink daffodil, known as 'Mrs R.O Blackhouse,' is vanishing from British gardens at an alarming rate, prompting an urgent call to action from horticultural experts. The flower, which has been a part of the UK's botanical heritage for over a century, is now so scarce that less than six percent of all daffodils in the country contain any trace of pink. The Royal Horticultural Society (RHS) has sounded the alarm, warning that without immediate efforts to preserve the variety, it may soon disappear forever. This is not just a loss for gardeners but a blow to the UK's rich horticultural diversity, which has long been celebrated for its vibrancy and historical significance.

The RHS's recent 'Daffodil Diaries' mapping project, which tracked daffodil sightings across the UK, revealed startling data. While yellow daffodils dominate the landscape, accounting for the majority of sightings, pink varieties—particularly 'Mrs R.O Blackhouse'—are becoming increasingly rare. According to Dr. Kálmán Könyves, RHS Principal Plant Scientist, the project has shown that the pink daffodil, though less popular than its yellow counterparts, holds unique qualities that make it a valuable part of the UK's flora. 'The adaptability of pink daffodils suggests they could thrive in a range of conditions,' he noted. 'Yet their decline is a cause for concern, especially as climate change and shifting gardening trends continue to reshape the landscape.'

To reverse this trend, the RHS has launched a campaign to revive 'Mrs R.O Blackhouse,' urging Brits to search their gardens for the flower and report any sightings. If found, gardeners are encouraged to donate the plants to Scamps Daffodils, a specialist breeder working to reintroduce the variety into wider cultivation. The initiative is part of a broader effort to preserve not only 'Mrs R.O Blackhouse' but also other rare daffodil varieties, including the white double-flowered 'Mrs William Copeland' and the orange and yellow 'Sussex Bonfire.'

The RHS has also invited owners of these rare blooms to contribute to a trial program at its research facility in Wisley, Surrey. By relocating the flowers to a controlled environment, scientists hope to study their characteristics, confirm their identities, and potentially discover new specimens that may have been overlooked. This is a critical step in ensuring the survival of these varieties, many of which are at risk of being lost to time. Guy Barter, RHS chief horticulturist, emphasized the importance of preserving such diversity. 'With 30,000 daffodil varieties available in the UK, each plays a role in supporting biodiversity and enhancing landscapes,' he said. 'Protecting these rare flowers is not just about saving a species—it's about safeguarding the legacy of British horticulture.'

The RHS's data also highlights broader trends in daffodil cultivation. Last year's survey found that 60 percent of daffodils in the UK were trumpet varieties, with all-yellow daffodils making up nearly half of those recorded. Meanwhile, the more delicate cup-shaped and double-flowered varieties accounted for a smaller share. This shift in popularity, combined with the decline of pink daffodils, raises questions about the long-term sustainability of certain types. 'We're seeing a preference for uniformity in flower color,' Dr. Könyves explained. 'But this uniformity could make the UK's daffodil population more vulnerable to environmental changes.'

As climate change continues to alter weather patterns, the RHS is also tracking how these changes affect flowering times. Last year's data showed that most daffodils peak in March, with the miniature 'tête-à-tête' variety blooming earlier, in February. However, this year's unusually mild conditions have led to earlier-than-usual flowering, raising concerns about how daffodils will adapt in the future. 'We need to understand how these plants respond to changing climates,' Dr. Könyves said. 'This data will help us predict shifts in flowering periods and identify which varieties are best suited to survive in a warmer world.'

For now, the onus is on the public. The RHS is calling on Brits to take action, whether by planting more pink daffodils, reporting sightings, or participating in the trial program. 'Every garden that hosts a 'Mrs R.O Blackhouse' is a small but vital step in preserving our horticultural heritage,' said Barter. 'If we don't act now, this flower—and others like it—may become little more than a footnote in history.' The race to save these rare blooms has never been more urgent, and the outcome could shape the future of British gardens for generations to come.
