Oxford (Oxford Daily) June 23, 2026 – Waitrose has announced that it is now the first UK supermarket to source home-grown samphire throughout the year, a move it says changes the availability of the sea vegetable for British shoppers. As reported by Waitrose Food & Drink, the supermarket said the development reinforces its commitment to British produce, local growers and sustainable innovation.

As reported by Tracey May, Fresh Prepared Produce Buyer at Waitrose, of Waitrose Food & Drink, the change removes what she described as a traditional 12-week window for British samphire. She said the retailer is aiming to deliver “premium, peak-season British quality” to shelves all year round.

Why is this seen as historic?

Waitrose says the shift is significant because British samphire has typically been a fleeting summer delicacy. The retailer says year-round supply changes that pattern by extending availability beyond the warmer months and into winter.

The company says this is a first for a UK supermarket and a first for British production at this scale using its current growing method. It has framed the launch as both a commercial change and a supply-chain milestone for fresh produce.

How is samphire being grown?

As reported by Hannah Stewart, Produce Technical Manager at Waitrose, of Waitrose Food & Drink, the crop is being produced in glasshouses that recreate coastal conditions. She said hydroponics makes it possible to grow samphire without soil while carefully adjusting salt levels and light.

Waitrose says LED lighting is used to replicate sunshine and saline solution is adjusted to match the crop’s needs. The retailer says this allows samphire to be grown continuously instead of being restricted to a natural seasonal cycle.

Who is supplying it?

Waitrose says it has partnered with British growers Westlands to make the year-round supply possible. The retailer says Westlands is the first UK producer to grow samphire all year round.

As reported by Will Boers, Director at Westlands, of Waitrose Food & Drink, the hydroponic model also improves water efficiency. He said the business recycles 85% of the water used in production.

What sustainability claims were made?

Waitrose says the new system supports sustainability by cutting air miles from imports. The company also says Westlands has installed a solar farm on its packhouse roof and a combined heat pump to power LED lighting.

The retailer presents the project as a supply-chain change that combines local sourcing with lower environmental impact. It also says hydroponic growing allows water to be collected, filtered and reused more effectively than ground-based cultivation.

Why do shoppers buy samphire?

Waitrose says demand for samphire has risen alongside interest in British produce, restaurant-style meals and foods linked to wellness. The retailer describes it as a versatile ingredient that can be used with fish, seafood, salads, pasta and barbecue dishes.

As reported by Paul Gamble, Senior Development Chef at Waitrose, of Waitrose Food & Drink, the appeal of samphire is tied to the current popularity of umami-rich flavours. Waitrose also says the crop is known for its nutritional benefits, including calcium and fibre.

What are the main customer implications?

For shoppers, the clearest immediate change is availability. Instead of a short summer purchase window, British samphire should now be available from Waitrose across the year.

That may matter most for customers who buy seasonal British vegetables, cook seafood dishes or want a consistent source of the product. It may also encourage more regular use in home cooking rather than treating samphire as a rare ingredient.

Background of this development

What led to this announcement?

Samphire has long been treated as a seasonal delicacy in Britain, with Waitrose saying the traditional supply window was about 12 weeks. The development comes as retailers increasingly highlight British sourcing and controlled-environment agriculture in fresh food supply chains.

The wider farming context is that hydroponic and glasshouse systems are being used more often to extend production seasons for specialist crops. In this case, Waitrose says the technology makes it possible to mimic the crop’s natural coastal habitat while keeping output steady throughout the year.

Prediction for shoppers

How could this affect the audience?

For Waitrose customers, the change is likely to make samphire a more reliable part of weekly shopping rather than a seasonal purchase. That could increase the chances that more households try it in everyday meals, especially alongside fish, pasta and salads.

For British produce buyers, the announcement may strengthen expectations that supermarkets will keep investing in local growing methods and year-round supply. For shoppers who prioritise sustainability, the water recycling and reduced import reliance may make the product more attractive, although the final impact will depend on price, shelf availability and consumer demand.
