How Temperate Gardens Are Becoming More Mediterranean — and What to Do About It

Climate change gardening is showing up in our backyards: longer dry spells, hotter summers, and milder winters. Many once-temperate regions now feel closer to a Mediterranean pattern. The good news? With Mediterranean garden plants, smart watering, and resilient design, your garden can thrive.

ClimateBanner
Key Takeaways (Quick Summary)
  • Temperate zones (e.g., UK, Pacific Northwest, Northern Europe) are trending hotter and drier with milder winters.
  • Adopt drought-tolerant plants and reduce lawn area to cut water needs.
  • Prioritise drip irrigation, mulching, and deep, infrequent watering.
  • Improve soil with compost and use ground covers to lock in moisture.
  • Design for shade (trees, pergolas, shade cloth) to protect heat-sensitive crops.
  • Look to real-world examples: English vineyards, Seattle gravel gardens, Berlin green roofs.

What Does a Mediterranean Climate Mean?

A Mediterranean climate (think southern Spain, Italy, Greece, coastal California) features hot, dry summers and mild, wetter winters with long stretches without summer rain. Traditional temperate regions used to rely on steadier rainfall and cooler summers - but that balance is changing.

The Climate Shift: From Temperate to Mediterranean

United Kingdom

Hotter, drier summers; the 2022 drought highlighted the need for water-wise gardens.

Pacific Northwest (USA)

Heatwaves are challenging lawns and moisture-loving plants once easy to grow.

Northern Europe

Longer dry periods (e.g., Germany, the Netherlands) are driving shifts in plant choice.

What This Means for Gardening

  • • Longer dry spells stress plants used to steady moisture.
  • • Hotter summers can scorch heat-sensitive plants.
  • • Milder winters allow more pests to overwinter.

Plants most at risk:

  • Lawns that need frequent watering
  • Shallow-rooted vegetables (e.g., lettuce) without shade or mulch
  • Moisture-loving ornamentals (e.g., hydrangeas, hostas)

Adapting Gardens to Climate Change: Practical Steps

1) Choose drought-tolerant plants

Swap thirsty species for Mediterranean garden plants and other tough choices:

Herbs: rosemary, thyme, sage, oregano

Shrubs: lavender, rockrose, oleander

Trees: olive, pomegranate, fig

Flowers: pelargoniums, echinacea, sedum

Tip: Plants with silvery leaves, deep roots, or aromatic oils often handle drought better.

2) Smarter watering

  • Drip irrigation targets roots and reduces waste.
  • Mulching (straw, wood chips, leaf mold) locks moisture in the soil.
  • Water deeply, not often to encourage deep roots (once or twice weekly instead of daily sprinkles).

3) Build water-holding soils

  • Add compost and organic matter to boost structure and moisture storage.
  • Use living ground covers (e.g., clover) to shade soil and reduce evaporation.

4) Design for shade

  • Plant trees or tall shrubs to shelter tender plants.
  • Use pergolas, trellises, or shade cloth over beds in peak summer.
  • Cluster pots so they shade and cool each other.

Examples of Success

English Vineyards

Grape growing is expanding in southern England - a sign that warmer, drier summers can support new crops and styles.

Seattle Gravel Gardens

Gardeners are replacing lawns with gravel and drought-tolerant plantings to cut water use while keeping beauty.

Berlin Green Roofs

Sedum, thyme, and lavender thrive in shallow soils and dry roof conditions - a model for resilient urban greening.

Quick Checklist to Start Today

  1. Replace portions of lawn with gravel, wildflower meadows, or low-water groundcovers.
  2. Favour perennials that handle dry summers over thirsty annuals.
  3. Harvest rainwater from roofs and store it for summer irrigation.
  4. Apply a thick mulch layer to reduce evaporation.
  5. Design for shade - place seats and tender plants under trees or pergolas.
  6. Experiment with new crops like figs, grapes, or almonds where feasible.

Conclusion: Adaptation Creates Opportunity

Climate change gardening is about adapting, not surrendering. As temperate zones grow more Mediterranean, gardeners can lean into resilient plant palettes, water-wise methods, and shade-savvy design. With drought-tolerant plants and better soils, your garden can stay beautiful, productive, and low-maintenance - even through hotter, drier summers.

Key Takeaways (Recap)
  • Shift plant choices toward proven Mediterranean and other drought-tolerant species.
  • Invest in drip irrigation, mulching, and deep, infrequent watering.
  • Improve soil with compost and protect it with ground covers.
  • Use trees, pergolas, and shade cloth to reduce heat stress.
  • Learn from regions already adapting: vineyards, gravel gardens, and green roofs.

Additional Resource: A Guide for Shifting Climates

Food Forest BookFood Forest Plants for Mediterranean Conditions: 350+ Perennial Plants For Mediterranean and Drier Food Forests and Permaculture Gardens. [Paperback and eBook]

This is the third book in Plants For A Future's acclaimed series, following volumes on temperate and tropical ecosystems. While it is written for Mediterranean climates like southern Europe, California, South Africa, Australia, and the Middle East, its value extends well beyond those regions.

For gardeners in traditionally temperate zones, this guide provides a ready-made toolkit for adapting to a hotter, drier future. The very plants chosen for Mediterranean food forests - hardy, drought-tolerant, multi-functional species - are exactly the ones that will help temperate gardeners cope with longer dry spells and heatwaves.

What the Book Offers

  • 350+ perennial plants suited to hot, dry summers and cooler, wetter winters.
  • Details on edibility: which parts can be eaten, how to harvest, and seasonal yields.
  • Guidance on plants that fix nitrogen, improve soil, and support wildlife.
  • Insight into ecological pioneer species that prepare the ground for future growth.

Some plants may not be directly edible, but their role in restoring degraded land and creating resilient ecosystems makes them invaluable in food forest design.

Why It Matters for Temperate Gardens

  • Swap water-hungry plants for drought-tolerant alternatives.
  • Design gardens and food forests that thrive with less water.
  • Build resilient ecosystems that are better prepared for climate extremes.

A Guide for the Future

As our article on Temperate Gardens Becoming More Mediterranean explained, adaptation is key. This book offers the practical plant knowledge gardeners need to future-proof their landscapes, turning climate challenges into opportunities for abundance, diversity, and resilience.

Food Forest Plants for Mediterranean Conditions is not just for gardeners in Spain or California - it's for anyone whose garden is facing the reality of hotter, drier summers.

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.
