We’re in for a long, hot summer, making it unsurprising that coastal gardens are trending for 2026. And if you’re looking to nail this look on a budget, B&M has some brilliant buys to snap up right now.

While coastal garden ideas are having a moment right now, they’ve been a classic garden design choice for decades. However, with this year’s garden trends prioritising climate-resilient planting and the warning of extreme heat becoming a new normal, drought-resistant coastal plants are becoming the new normal for UK gardens.

And to complete the look, this, of course, means the surge in popularity of coastal garden accessories. From rattan plant pots to glowing lanterns, here are the affordable coastal garden buys to snap up from B&M right now.

‘Coastal garden decor is all about creating a space that feels calm and natural. As more people make the most of their outdoor space, they're looking for gardens that capture that holiday feeling and somewhere to really switch off. Coastal style lends itself perfectly to that with its relaxed colour palette and a look that never feels too polished,’ explains Dayna Isom Johnson, Etsy's trend expert.

‘The key is to keep the look subtle. Natural textures, striped cushions and beach-inspired ceramics bring in a coastal feel without making the space look overly themed. Handmade pieces work especially well because they add character and make a garden feel collected over time. It's about capturing that easy, lived-in feeling rather than trying to recreate a beach on your patio.’

If you want your garden to look like something out of a Nancy Meyers film, aka the coastal grandma aesthetic, you can’t go wrong with rattan. From rattan planters (like this Dunelm plant pot) to even a rattan garden water butt (£500 at Garden Trading), rattan is one of the easiest ways to nail the coastal look.

You should also consider a cream and blue colour palette. Add nautical stripes to your gardening furniture in the form of the best outdoor pillows. I like this Deck Stripe Cushion from Wayfair, which looks just like a stereotypical striped sailor's shirt. And lastly, you can’t go wrong with some nautical finishes like this White Company Whitewashed Bamboo Lantern (£45).

‘For those sunny afternoons, a sun lounger is the ideal garden companion for sunbathing, and adding a parasol for protection finishes the look and creates a relaxing spot for a laid-back summer day. Plus, with parasols with fringed edging, add a fun, retro-inspired element (reminiscent of 1970s beaches), transporting you back to fond memories of your favourite holiday destinations,’ adds Helen Barlow-Davis, product development manager at Laura James.

‘Accessories can also do a lot of heavy lifting. For example, bring in colour with ocean blues with cushion covers and throw blankets, which work for outdoor sofas and seating areas. Plus, as the sun sets, soft lighting can transform your garden into a tranquil outdoor retreat. Lanterns, warm string lights, and solar-powered lamps add a subtle glow reminiscent of beachside evenings. Placed along pathways or around seating areas, they create a welcoming atmosphere perfect for relaxing or entertaining.’

B&M’s products are only available in-store. If you don’t have one local to you, I’ve rounded up a few more coastal alternatives that you can shop online.
