Purple Reign: Why This Shade Is Britain's Top Garden Color 2026

Purple has become British gardeners' favorite color, according to recent research by the Royal Horticultural Society (RHS). This bold shade now leads in popularity, overtaking traditional greens and soft pastels. If you're looking to refresh your outdoor space, understanding why purple reigns supreme can help you create a stunning, on-trend garden.

Why Purple Is the New Garden Favorite

The RHS conducted a large-scale experiment at RHS Garden Wisley's Hilltop, where over 11,000 visitors were asked to choose their preferred flower colors. Purple hues received the strongest preference at 26.67%, closely followed by red at 25.24%. This marks a significant shift from the grey and muted tones that dominated recent garden design.

Tom Massey, an award-winning London garden designer, notes that clients now want vibrant, naturalistic planting. "We've moved away from the era of large expanses of decking, paving, and lawn towards richer, more naturalistic planting inspired by meadows and natural plant communities," he says.

Top Purple Plants to Grow

If you're ready to embrace this trend, consider these popular purple-flowering plants:

• Lavender – Classic, fragrant, and pollinator-friendly.
• Salvias – Hardy, long-blooming, and available in many shades.
• Catmint (Nepeta) – Soft, billowy, and perfect for borders.
• Alliums – Dramatic spherical blooms that add structure.
• Geraniums – Versatile and easy to grow.

The Psychology Behind Purple's Appeal

Research suggests that purple and blue tones evoke a sense of calm and relaxation, which may explain their popularity in gardens. In contrast, yellows and oranges bring energy and warmth. By incorporating purple, you can create a peaceful retreat right outside your door.

Laura Carey, co-owner of Carey Garden Designs, confirms that purple is a favorite across all her clients. "There are so many purple flowering plants to choose from, including national favorites like lavender, alliums, and geraniums," she says.

How to Design with Purple

Purple combines beautifully with greens, silvers, and the buff tones of ornamental grasses. It also attracts pollinators, making it an eco-friendly choice. Here are some design tips:

• Pair purple with silver foliage (e.g., lamb's ear) for contrast.
• Use purple in drifts for a naturalistic meadow look.
• Add purple near seating areas to enhance calmness.
• Mix with yellow or orange for a vibrant pop.
