The Gibraltar Campion: Back From Extinction

25 June 2026 Last checked 2026-06-25

Declared extinct, then found again on the Upper Rock in 1994, the Gibraltar campion survives today mostly by human hands. Its story is remarkable.

In 1992, botanists in Gibraltar quietly closed the file on a flower. The Gibraltar campion, a soft pink wildflower that grew wild nowhere else on the planet, had not been seen for years. For a species with a single home, that silence was as good as an obituary. The plant survived only as pressed sheets in a herbarium, a handful of old records and the memory of people who had once known where to find it.

Two years later, on a rocky outcrop high on the Upper Rock, three botanists found it alive. A flower the scientific world had written off had simply gone unnoticed. What happened next is one of the quietly extraordinary survival stories on the Rock, and you can stand in front of its living proof today, for free, without so much as a climbing rope.

A flower found nowhere else on Earth

Silene tomentosa belongs to the campion and catchfly genus Silene, in the carnation family. It is a woody based perennial reaching roughly forty centimetres, with soft, faintly downy leaves and bilobed petals. On the colour, be more careful than most pages are: the Gibraltar Nature Reserve and the conservation literature describe flowers ranging from white through pale pink to violet, not simply pink. The reserve adds a detail almost nobody mentions, which is that they scent the evening air. The species name tomentosa refers to the fine felting of hairs on the foliage.

It was described by the Swiss naturalist Carl Adolf Otth in the early nineteenth century, and from the beginning it was understood to be peculiar to Gibraltar alone. Endemism on this scale is unusual. Plenty of plants are scarce, but very few are restricted to one rock at the mouth of the Mediterranean and nowhere else. The Rock is not one of its homes. It is its only home, which is why losing it here would have meant losing it everywhere at once.

Why the Rock breeds such rarities

The Rock is a tilted block of Jurassic limestone rising sharply from the sea, and its geology does odd things to plant life. Sheer cliffs, shaded fissures, salt laden winds off two seas and pockets of thin calcareous soil create a mosaic of micro habitats packed into a tiny area. Plants that would be outcompeted on open ground can hold on at a ledge almost nothing else can reach. The Upper Rock alone carries some 363 species of flora, a few of them found only here and in the Strait region.

All of it sits inside the Gibraltar Nature Reserve, which covers about 40% of the territory's total area. If you want the wider picture of the limestone massif, our Rock of Gibraltar guide sets the scene, while the famous residents of the slopes are covered in our Barbary macaques guide.

Declared extinct, and then found

The campion's modern story is a study in how hard it is to be certain a plant has truly gone. Botanists working beyond Gibraltar had concluded the species was extinct. Locally the picture stayed more hopeful for a while: the botanical section of the Gibraltar Ornithological and Natural History Society still knew the plant survived somewhere on the cliffs in 1985. By 1992 the society too reluctantly accepted it was probably gone. For a flower found in one place and one place only, that was as close to a death certificate as a plant can receive.

Then, in 1994, it was found again, growing wild inside the Upper Rock Nature Reserve. The finders were three Gibraltarian naturalists: Leslie Linares, Arthur Harper and John Cortes, later Gibraltar's Minister for the Environment, who marked the anniversary publicly years afterwards. Their find was written up in the botanical literature in 1996. The UK Overseas Territories Conservation Forum notes that the rediscovery prompted much surprise, it being unusual for a fairly conspicuous plant to have escaped detection in somewhere as small and as thoroughly recorded as the Rock.

What we cannot tell you, and why that matters

Most pages about this flower, including an earlier version of this one, state that exactly three plants were found in 1994 and that the last wild individual was seen in 2008. We went looking for the source of those two numbers and could not find one.

The plant count varies by retelling. Some accounts say a single specimen found by a climber. Others say three. None of the versions we could reach cites the 1996 paper or any field record, and the search engines now return this very page as a source for the figure of three, which is a tidy demonstration of how an unsourced number becomes a fact by repetition. We are not going to keep feeding that loop.

The 2008 date is worse, because it may be wrong rather than merely unsourced. The Gibraltar Nature Reserve's own flora page still describes the campion as a rare plant that a visitor may stumble across in the reserve, which is not how you describe a species with no wild presence at all. What is solid is this: the wild population is tiny, it is not self sustaining without help, and the species exists today chiefly because people propagate it. If you want the exact wild count or a confirmed last sighting, the people to ask are the Gibraltar Botanic Gardens and the Department of the Environment, not a travel blog.

A species declared extinct had quietly carried on, out of sight, waiting to be noticed.

Why it nearly went, and what still threatens it

The post you are reading used to skip this part, which was a mistake, because the causes are the most useful thing in the story. Historically the campion lost ground to building and military works across the Rock. Today its potential habitat is essentially the nature reserve and nothing beyond it.

Two pressures stand out in the conservation assessment. Firebreaks that were traditionally maintained have been allowed to lapse, which reduces exactly the open habitat the campion favours. And the reserve is dealing with fast spreading invasive plants, from Hottentot fig, Carpobrotus edulis, to African flag, Chasmanthe floribunda, which form dense mats that smother native vegetation and stop it regenerating from seed. A cliff ledge is a refuge only until something else gets there first.

The plant has legal protection under Gibraltar's Nature Protection Act 1991, and the 2016 Gibraltar Nature Reserve Management Plan calls for continued habitat management and reintroduction work. Protection on paper and habitat on the ground are different things, and the second is the harder one.

Kew, the Millennium Seed Bank and the rescue

The response to the rediscovery was swift. Seed was collected from the surviving plants and material went to the Royal Botanic Gardens, Kew, where the type specimen of the species is held, and the campion was propagated through the Millennium Seed Bank. Seed banking is insurance: even if every living plant died, the genetic blueprint would survive in cold storage. For a flower hanging on by a handful of individuals, that was not a luxury.

Living collections are now held both at the Gibraltar Botanic Gardens and at Kew, alongside the banked seed, which is what conservationists mean by keeping a reservoir of genetic diversity for future reintroduction. The campion is grown from seed successfully enough that the Alameda produces it in quantity each year. We have seen the figure of hundreds of plants annually repeated widely, and it is plausible, but we have not found an official number and will not invent one.

A timeline, with its evidence

Where to see it

You do not need climbing gear to meet the Gibraltar campion. The most reliable place is the Alameda Botanic Gardens in the heart of town, the same gardens that anchor the propagation effort. The Alameda has deep roots: it was established in 1816 by Lieutenant Governor Sir George Don, and the gardens themselves record that they were rehabilitated and converted to a botanic garden in 1991, taking on education, research and plant conservation.

The practical details, from the gardens' own visitor information: admission is free, and they are open every day from 8am until sunset. The site covers about six hectares of terraced limestone beds and shaded paths. Seeing the campion here is not the same as finding it wild, but there is something genuinely moving about standing in front of a flower that exists at all only because three people went looking and a lot of others kept sowing.

Planning the visit

One thing to get right before you plan a day around the flower and the reserve above it. The cable car is closed for reconstruction until 2027, so the Upper Rock means driving, taking a tour vehicle or walking up. That changes the shape of the day considerably, and plenty of itineraries online have not caught up.

Go to the gardens early. They open at 8am, the light is better, and the town is quiet. If you are building a wider itinerary, our 48 hours in Gibraltar weekend guide shows how a garden visit slots in alongside Main Street and the Upper Rock. Do not expect a labelled showpiece bed with crowds around it: this is a modest plant, and finding it is part of the point. Ask at the gardens if you cannot spot it.

A small flower with a large lesson

The Gibraltar campion will never draw the crowds the macaques do, and it asks nothing of the visitor beyond a few quiet minutes. Its story is still among the most remarkable on the Rock. It is a reminder that extinction is not always final, that rediscovery is possible, and that the survival of an entire species can come down to seed bags, greenhouse benches and people stubborn enough to keep sowing.

It is also a reminder to check what you are told. The most repeated numbers about this flower turn out to have no visible source, which is worth knowing before you repeat them yourself. The documented story is remarkable enough without them.

When you have found the campion, the rest of it is laid out above you: the reserve where the last wild plants hold on, the cliffs that bred such a rarity, and the limestone slopes that 363 species of flora share with the macaques. The flower is the small, quiet beginning of a much bigger day out.

Victory Suites makes that day easy to build around. From our base on Devils Tower Road you can be at the Alameda Botanic Gardens in a gentle stroll, then carry on to Grand Casemates Square about ten minutes away on foot and up to the Upper Rock beyond. We offer more than 100 serviced apartments with full kitchens, so you can breakfast early and reach the gardens as they open, plus an indoor pool and a gym for when you come back down off the Rock. Our team can map the gardens and the reserve into a single unhurried day, and with Gibraltar International Airport minutes away you can be looking at a flower that came back from the dead within an hour of landing. Stay with Victory Suites and come and meet it.
