In North London, drought-tolerant perennials such as salvias, heather, and dahlias are replacing traditional bedding plants. These provide vibrant colour, attract pollinators, and thrive with less water and maintenance—ideal for busy city lifestyles.
Simon Toomer, the curator of living collections at Kew Gardens, summed it up well:
“We’re trying to be more positive in our thinking about how we adapt gardens and habitats to the threat of climate change and the carbon cycle, and highlight some of the solutions – or at least the mitigations – that we can make to manage some of the impacts of climate change.”
Clay Soil Solutions for London Gardens
One of the most persistent challenges facing London gardeners involves managing the capital's heavy clay soils, which can become waterlogged in winter yet crack during summer droughts. Expert horticultural advice now emphasises improving drainage through organic matter incorporation, with well-rotted garden compost proving particularly effective for transforming challenging growing conditions.
Watering and irrigation systems specifically designed for London's clay-heavy soil have become essential for gardens ranging from compact Crouch End patios to sprawling Hampstead estates.
These systems must accommodate North London's unpredictable weather patterns, from scorching July droughts to sudden September downpours, making smart, adaptive irrigation crucial for plant survival.

Outdoor Living, Edible Perennials & Superfruits in Urban Spaces
By 2030, the UK outdoor kitchen market is estimated to be worth $2.5 billion (£1.82bn) according to a report by Grand View Research. With the expansion of outdoor living and an uptick in outdoor kitchens, edible plants go hand in hand with these lifestyle changes.
One major 2025 trend is blending ornamental and edible plants, creating gardens that are both beautiful and productive. Blueberries are especially popular in London, offering spring flowers, summer fruit, and autumn colour. Their compact form and success in containers make them perfect for balconies and roof terraces.
Honeyberries (edible Lonceria) are also rising in popularity. These early-fruiting, low-maintenance plants thrive in UK conditions, providing a productive yet visually appealing option for urban gardens, allotments or fruit cages.
Herbs and Aromatics Integration
Mediterranean herbs like lavender, rosemary, and thyme continue dominating London plantings, but their application is evolving beyond traditional herb gardens. These plants are being integrated into mixed borders where their architectural qualities complement flowering perennials while providing year-round structure and fragrance.

Vertical Gardens, Living Walls and Small Space Innovation
Urban space constraints have sparked remarkable innovation in vertical growing techniques, particularly relevant for London's dense housing areas where every square metre must maximise both aesthetic and functional value.
Vertical gardening is a core component of ‘Hortifuturism’ in urban spaces, and green walls are reaching new heights in 2025, bringing lush vegetation to previously unusable vertical surfaces while providing thermal regulation for buildings. These installations help manage stormwater runoff, reduce urban flooding risks, and create vital wildlife corridors through the city's built environment.
The technology supporting vertical gardens has advanced significantly, with modular systems incorporating integrated irrigation and seasonal plant rotation capabilities. For gardens under 50 square metres, vertical growing can effectively triple available planting space, making it possible to achieve substantial green coverage even in the most constrained urban settings.

Micro Forest Gardening and Layered Ecosystems
Forest gardening principles are being adapted for urban environments, creating multi-layered plantings that mimic woodland ecosystems while requiring minimal maintenance. This approach proves particularly valuable for North London gardens where mature trees already provide natural canopy structure.
“Micro forests” as small as 3 × 3m are being created and showcased, demonstrating how many perennial edible crops you could grow together in a small space within your own garden. Even compact urban gardens can incorporate forest gardening principles through careful layer selection.
Compact tree varieties form the canopy layer, with smaller shrubs and perennials densely positioned beneath to create self-sustaining plant communities. This approach works exceptionally well in shaded areas common to London's Victorian terraces.
The layered approach extends to container gardening, where large pots accommodate multiple plant stories from small trees down to ground-covering plants. This technique creates the visual complexity and ecological benefits of forest gardening even on balconies and roof terraces.
Native Plants and Biodiversity Focus
British gardeners are increasingly incorporating native species into their planting schemes, with the National Wildlife Federation recommending that gardens strive for 70% native plants to support local ecosystems. This trend reflects growing awareness of gardens' crucial role in supporting urban wildlife populations and maintaining ecological corridors through built environments.

Pollinator-Friendly Plantings
The emphasis on pollinator support has transformed plant selection criteria, with flowering schedules becoming as important as aesthetic considerations. Gardeners are selecting plants that provide nectar sources from early spring through late autumn, creating continuous food supplies for bees, butterflies, and other beneficial insects.
Native options like cow parsley, purple moor grass, and hawthorn are being integrated with non-native but pollinator-friendly species to create diverse, ecologically valuable gardens. This approach supports local wildlife while maintaining the visual appeal essential for urban garden design.
Creating wildlife-friendly spaces has become a priority for London gardeners, with over 14,000 different species of plants, animals and fungi recorded in London. Garden features like bird boxes, hibernation shelters, and small water features being integrated into garden designs. These elements support urban biodiversity while adding interest and educational value for families.

Cutting Gardens and Seasonal Flower Production
UK flower production jumped from £126m in 2019 to £179m in 2023, according to figures from the Department for Environment, Food and Rural Affairs. As such, cutting gardens are rising in popularity as sustainable sources of fresh flowers that link indoor and outdoor spaces. They combine environmental benefits with the joy of home flower arranging.
Gladioli, dahlias, lupins, Shasta daisies, and asters are favoured for their long flowering seasons, visual impact, and vase life. The trend also includes herbs and foliage plants, chosen for both culinary use and floral arrangements—maximising value in limited spaces.

Bold Colour Trends and Mediterranean Influence
Garden palettes in 2025 shifted from soft pastels to bold, saturated tones for greater impact. Deep purples, burgundies, and blues define the rising gothic aesthetic, offering striking contrast against metallic foliage and architectural plants. Bronze and purple-leaved varieties extend this trend into foliage, ensuring year-round colour, even through winter.
Mediterranean influences are also growing, with silver-leaved plants, succulents, and aromatic herbs creating sun-drenched, coastal-style spaces—especially suited to South-facing courtyards and terraces.
