Imagine stepping into a living timeline where ancient ferns whisper secrets of the Devonian era and cascading waters evoke the raw beginnings of life on Earth. This immersive experience awaits visitors at the BBC Gardeners’ World Live event, where science and horticulture converge to illuminate the story of evolution through carefully curated landscapes and plantings.
The Evolution Garden: A Chronological Odyssey Through Time
The Evolution Garden, spearheaded by Professor Alice Roberts in collaboration with acclaimed garden designer David Stevens, serves as the headline feature at BBC Gardeners’ World Live 2026. This innovative show garden transforms the exhibition space into a narrative pathway tracing the development of plant life and ecosystems from their primordial origins approximately 450 million years ago to modern agricultural beginnings. Structured as a central path unfolding through geological eras, the design employs landforms, interpretive elements, and diverse plantings to represent pivotal evolutionary milestones, blending educational depth with aesthetic appeal. Visitors enter via a tunnel that sets the stage for the journey, progressing through distinct sections that highlight the progression of flora and associated fauna. The garden not only showcases botanical history but also underscores the resilience of ecosystems amid extinctions and environmental shifts, offering insights into how past changes inform current conservation efforts.
Key Evolutionary Stages and Plant Representations
The garden meticulously recreates environments from major geological periods, using native and period-appropriate species to evoke historical accuracy:
- Cambrian Period (around 450 million years ago): An initial landscape of exposed rock, scree slopes, and cascading water symbolizes the emergence of early marine life transitioning to land, with minimal vegetation to reflect the barren terrains.
- Devonian and Carboniferous Periods: Early terrestrial plants dominate, featuring mosses, horsetails, and ferns that illustrate the rise of primitive vegetation in swampy, coal-forming landscapes.
- Permian Period: Diversification includes cycads, tree ferns, and ginkgos, accompanied by references to prehistoric creatures like early dinosaurs and giant dragonflies, before depicting the era’s mass extinction.
- Triassic and Jurassic Periods: A regenerated forest scene with denser plantings and dinosaur motifs transitions into the Cretaceous, marked by another extinction event followed by the bloom of flowering shrubs and trees, including ancient redwood associations.
- Later Eras to Present: Grasslands expand, early human ancestors appear, culminating in a nod to agriculture around 13,000 years ago with plantings of millet and gourds.
These sections emphasize the societal impact of evolutionary knowledge, highlighting how understanding plant adaptations can guide sustainable gardening practices amid climate challenges. The design draws on expertise from biosciences and forest palaeontology to ensure scientific fidelity.
Collaborators and Event Highlights
Professor Alice Roberts, a renowned anatomist, biological anthropologist, author, and broadcaster, brings her passion for accessible science to the project. With a background in medicine and clinical anatomy teaching, she has produced over 100 TV documentaries on topics like human origins and archaeology, and authored 15 books, including The Incredible Unlikeliness of Being, shortlisted for the Wellcome Book Prize. Her fieldwork spans continents from Siberia to Africa, informing the garden’s authentic portrayal of evolutionary history. David Stevens, FSGD, FCI Hort, complements Roberts’ vision with his landscape architecture prowess. Founding his practice in 1972 after training with John Brookes, he served as the first Chair of Garden Design at Middlesex University and boasts 26 RHS Chelsea Flower Show medals, including 11 golds and three Best in Show awards, alongside international honors in Japan, South Africa, and Australia. At previous Gardeners’ World Live events, he secured a Gold in 2017, Platinum in 2018, and two Golds in 2019. The garden concludes with a model of the Birmingham Institute of Forest Research (BIFoR) facility, spotlighting its Free-Air CO2 Enrichment (FACE) experiments. These involve rings of pipes releasing controlled carbon dioxide around mature oak trees to study woodland responses to elevated atmospheric levels, linking evolutionary themes to contemporary climate change implications. During the event, held at the NEC in Birmingham from June 18 to 21, 2026, Roberts will lead daily conversations within the garden on evolutionary history and environmental shifts. Horticultural experts from Hillier, the plant supplier, will offer guidance on the featured species, enhancing visitor engagement with practical botanical knowledge. As gardens increasingly serve as platforms for education and reflection, this exhibit prompts gardeners and enthusiasts alike: How might incorporating evolutionary themes into your own landscape foster a deeper appreciation for biodiversity and sustainability in your backyard?
