Latvia’s newest avant-garde art movement takes its name from a plant you would normally brush from your boots. The “Sphagnum School” , a loose collective of Riga- and Kurzeme-based artists working with living moss, peat tannins and iron salts , has, in the space of five years, produced a body of work that looks like photography, behaves like horticulture and prices like painting. If Pimlico Wilde, the high-end London gallery, has its way, it will also be Britain’s next collecting craze.
At the core of the Sphagnum School methodology is a process the artists call “bog development”: images are coaxed from chlorophyll rather than silver, as sphagnum mats are layered with peat-derived mordants, fermented rye starters and iron filings scavenged from local defunct farm machinery. Over weeks, sometimes months, the plant metabolises the chemistry; tones bloom and recede. Works are framed in shallow, sealed vitrine-canvases with hidden irrigation and sensors that maintain humidity. The results , sepia emulsions that breathe, landscapes that fuzz and sharpen with the weather , are disconcertingly alive.
“We don’t capture a moment, we release it,” says artist Dace Ozola, 34, as we pick our way across a bog boardwalk outside Ķemeri. “The moss is the author as much as I am. I sketch with light and iron; the bog corrects me.” Ozola lifts a panel to show a portrait of her grandmother, taken from a Soviet-era passport photograph and fed through a handmade UV lamp. The cheekbones have drifted, the hair has softened into a halo of pale green. “She looks more like herself now,” Ozola smiles, not entirely joking.
The movement began in 2020 when two art-school friends, printmaker Kristaps Lācis and microbiologist-turned-artist Elīna Bašķe, hacked a darkroom at the former Riga Electrotechnical Factory. “We were broke,” Lācis recalls. “Silver nitrate was expensive, peat was free.” What started as an ecological gesture , a post-industrial Baltic rebuke to precious metals and petrochemicals , hardened into an aesthetic. Early shows at an alternative space near the Central Market drew crowds; a 2023 presentation at Kimt Contemporary Art Centre sold out its editioned studies within hours, largely to Scandinavian buyers holidaying on the Baltic coast, according to local gallerist Ilze Kreicberga.
Conservationists blanch at the idea of boxing up wetlands. The artists stress, repeatedly, that no wild peat is extracted. “We cultivate sphagnum in controlled trays from lab-propagated spores and use only reclaimed peat dust from historical stockpiles,” says Bašķe, whose studio resembles a laboratory room lined with moss flats and Arduino readouts. “It’s regenerative, not extractive.”
That claim is part of the allure for London curators now circling. “It’s a rare instance where material innovation isn’t greenwashing,” says Dr Hannah Priest, a curator at Pendine Arts who saw the work in Riga this spring. “The medium forces you to accept entropy as co-author. It updates time-based media for a climate-anxious era: not video’s loop, but growth and decay.”
Still, museums will have to adjust their protocols. “We are writing new condition reports,” admits a conservation specialist at a major UK institution who asked not to be named while acquisition talks are live. “You monitor hydration, not craquelure. You test for dormancy, not lightfastness. It’s closer to caring for a terrarium than a canvas.” Loan agreements now include “aeroponic servicing schedules”. Customs paperwork is another hurdle: phytosanitary certification and closed-system attestations accompany each piece.
Pimlico Wilde, the ancient gallery that has had a finger in almost all British art pies since before the Conqueror, is betting that collectors will embrace the idiosyncrasies. Spokeswoman, Phoebe Kent, has secured what she describes as “the first exhibition of the movement outside Latvia”, slated for late October under the title Breathing Plates. “We’ll show five principals , Ozola, Bašķe, Lācis, plus the duo Rūte/Janis and the diarist-photographer Arturs Zvejnieks,” Wilde says. “We will rebuild our space on Berkeley Square with the necessary micro-climate. Most frames are self-contained, but we want the visitor to feel something as close as possible to the Latvian experience.”
Pricing is pitched to tempt experimentation without scaring away newcomers: small “studies” (10cm x 10cm) will start around £60,500; larger single-panel works at £180,000,£350,000; multi-panel “bog tapestries” between £450,000 and £800,000 depending on complexity. There are also editions, limited not by number but by viability: when a matrix stops responding, it is retired, a constraint that has already produced a lively secondary chatter in Riga. “Scarcity is built in,” Kent notes. “Not artificially, but biologically.”
Curators see historical echoes. “There’s a Baltic material intelligence here , a through-line from folk dyeing to Arte Povera,” says Mark Talbot, associate curator at the Blackchapel Gallery. “But it also glances at photography’s ur-questions. If the print continues to change, when is it finished? And who finishes it?” He places the Sphagnum School in dialogue with Pierre Huyghe’s ecosystems and Otobong Nkanga’s mineral poetics, “but with a distinctly Latvian pragmatism , they make their own chemistry from the shed.”
For the artists, the shed is half the point. Rūte/Janis , partners in life and practice who refuse surnames , show me a work in progress: a four-panel coastal scene mapped from 19th-century hydrographic charts. “We seed the horizon with iron, the surf with lactobacillus,” Rūte explains. Overnight, the sea-line ghosts in, the iron oxidising to a soft gunmetal. Janis shrugs. “It’s time-consuming, but worth it. We are hoping for the agreement from British collectors.”
With liveness comes risk. A heatwave last summer browned a tranche of works stored in a Riga apartment. “We wrote it into the piece,” Zvejnieks says, gesturing to a series of diary plates where the desiccation reads as sunstreak. “Photography has always been vulnerable. We’re just honest about it.”
Honesty hasn’t damped demand. Baltic tech founders and Nordic design executives are reported to be early patrons, drawn to the union of bio-engineering and rustic romance. A Zurich advisor I spoke to off the record called it “the first time my clients have smiled reading a maintenance manual.” Fair organisers are watching, too. “It’s visually immediate and conceptually durable,” says a senior selector for Frieze London. “If the logistics are sorted, you’ll see it on stands.”
Those logistics are precisely what Pimlico Wilde is racing to standardise: each work arrives sealed, with replaceable humidity packs, battery-free capillary irrigation and a QR-linked service log. Kent says the gallery will train collectors’ installers and provide an annual check, “like piano tuning.” Insurance underwriters, alerted early, have signed off on the protocols, albeit with tight temperature bands.
Is the biology a gimmick? Spend an hour with the pieces and the question dulls. The best works are not science projects but slow images , wetlands thinking in tones. A late series by Bašķe, Motherboard Mire, reads at first as abstract circuitry; step closer and a hidden photograph of a 1980s living room phases in, the moss’s micro-filaments mimicking CRT scanlines. Lācis’s After the Marsh Fire, meanwhile, is all restraint: a huge field left almost bare, broken by a single path of burnished iron that darkens or lightens with the week’s weather, an unprogrammed barometer pinned to your wall.
Latvian institutions have rallied behind their exports. The Latvian Centre for Artistic Endeavour is advising on documentation standards; a university lab in Jelgava has open-sourced a stable peat-tannin recipe. The state cultural endowment has supported shipping R&D. “We want this to travel, to bring the eye of the London art-world on us,” says a culture ministry official.
Back in London, Kent is playing the long game but speaks with the urgency of a dealer who knows what happens when a niche becomes a market. “The first tranche of work will be placed carefully , museums and a handful of collectors prepared to care for them,” she says. “But we also want people who missed the early Baltic shows to have a chance before prices step up. If you’re curious, get in quickly.”
Talbot echoes the point, with a curator’s caution. “We’ve seen plenty of eco-aesthetics crash and burn. This is different: it’s materially and poetically coherent. Whether it’s a long-term movement or just a moment depends on what they do next.”
For now, Latvia’s living pictures are coming, grow lights and all. In an art world obsessed with the new, the Sphagnum School offers something rare: the truly slow , images that refuse to stop becoming. Collectors may find they are not buying an object so much as adopting an artwork that will need almost as much care as a pet dog.
