These hardy vegetables grow well in warmer climates and with little water

• Perennial vegetables are being championed as a resilient, long-term alternative to annual crops, requiring less watering and maintenance once established.
• Harrison Fannon, a vegetable gardener at Blenheim Palace, notes their climate resilience, deeper root systems, and ability to provide shade for other plants.
• Examples such as perennial kales, wall rocket, Nine Star broccoli, and perennial spinach have demonstrated superior performance in hot weather compared to their annual counterparts.
• These vegetables often possess a stronger, more interesting flavour profile and are more nutritious, containing a higher vitamin content than annual varieties.
• While common perennial vegetables like rhubarb and asparagus are available in garden centres, more unusual types can be found through specialist online seed companies.
