Purple Reign: Why Gardeners Now Favor Purple Flowers 2026

Purple has become the favorite color among British gardeners, according to new research from the Royal Horticultural Society (RHS). This vibrant hue is now the top choice for flower beds, with lavender, salvias, and catmint leading the trend. Gardeners across the UK are embracing purple for its beauty and calming effect.

Why Purple Is Dominating British Gardens

The RHS conducted a study at RHS Garden Wisley’s Hilltop, where over 11,000 visitors were asked to select 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 muted grey tones that have dominated garden design in recent years.

Tom Massey, an award-winning garden designer, notes that clients are moving away from minimalist hardscaping toward richer, naturalistic planting. He explains, “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.”

The Appeal of Purple Plants

Purple flowers are not only visually striking but also offer practical benefits. They attract pollinators like bees and butterflies, and they have a calming quality that many gardeners find therapeutic. Laura Carey, co-owner of Carey Garden Designs, says, “Purple is a favourite across the board with all of our clients. There are so many purple flowering plants to choose from, including national favourites like lavender, alliums and geraniums.”

Designers also appreciate how purple pairs with other garden elements. Massey adds, “Purple has always been a hugely important colour in gardens because it combines beautifully with greens, silvers and the buff tones of ornamental grasses.”

For best results, plant in clusters and choose varieties that bloom at different times to extend the season.

Research suggests that purple and blue tones evoke a sense of calm and relaxation, making gardens a sanctuary from daily stress.
