A brand-new plant species has officially been added to the botanical record, found nowhere else on Earth except a single hillside in the Western Cape!
Western Cape, South Africa (03 July 2026) – Good news is blooming in the Overberg!
Lachenalia groenewaldii – a delicate little bulb with cream-coloured, pink-tinged flowers – was recently formally described to science in May 2026.
It grows only within the Haarwegskloof Renosterveld Reserve, located between Bredasdorp and Swellendam, and its entire known population numbers just around 100 plants!
The story of this little flower is a lovely reminder that good discoveries often start with someone casting a close eye. More than a decade ago, in 2014, then Reserve Manager Jannie Groenewald spotted something unusual while out on the reserve. The plant looked like it belonged to the Lachenalia family, but something about it seemed different.
Instead of dismissing it, Jannie raised the question with the team at the Overberg Renosterveld Trust (ORT) and with botanist Graham Duncan, who took an interest in the mystery plant.
The plant then vanished from view for years, only reappearing in October 2023. This time, ORT’s Senior Conservation Manager Grant Forbes was able to collect proper material from the population, giving Duncan what he needed to study it in detail.
This brought the confirmation that the flower wasn’t just an unusual-looking relative of a known plant, it was an entirely new species, never before recorded by science!
In honour of the sharp eye that started it all, the new species was named Lachenalia groenewaldii, after Jannie Groenewald himself.
Lachenalia groenewaldii is rare and remarkably particular about where it lives. Its only known population grows in Eastern Rûens Shale Renosterveld, one of South Africa’s most threatened vegetation types. More than 80% of this habitat has already been lost, mostly to agriculture, which makes every remaining pocket of it precious.

Lachenalia groenewaldii is actually the second new Lachenalia species to be found at Haarwegskloof in under ten years, following the description of Lachenalia barbarae nine years earlier, the Overberg Renosterveld Trust shares. Interestingly, the two species grow only a short distance apart, though L. barbarae tends to favour quartz patches at a slightly higher elevation.
This newly discovered flower proves to us that these fragmented and often-overlooked ecosystems still have much to teach us. Protecting the little bits of them that remain matters.
“The discovery also highlights the value of long-term conservation. Without protected areas such as Haarwegskloof, species like this could easily disappear before they are documented.” shares the trust.
