As the new year begins, our outdoor spaces seem more important than ever. This week we're looking at gardening can benefit the mind, body and soul. Grower and forager Poppy Okotcha shares the seasonal delights of winter purslane (Claytonia perfoliata) – a little-known salad plant that can provide fresh, healthy greens throughout the coldest months. Award-winning garden designer Juliet Sargeant gives her thoughts on how the way we garden will change in 2021, and what she's doing on her own plot to encourage wildlife. Plus the RHS's first 'Wellbeing Fellow', Dr Lauriane Suyin Chalmin-Pui details the results of a four-year scientific study onto how having a green front garden can reduce stress and improve your mental and physical health.
