Jersey tiger, vapourer, Mother Shipton... this month we flutter into the weird and wonderful world of day-flying moths with RHS scientist Dr Stephanie Bird. Back on the ground, multiple award-winning herb grower Jekka McVicar shares wisdom gained from a lifetime of working with, growing, cooking and preserving aromatic plants. Plus legendary plantsman Roy Lancaster takes us on a voyage to far-off lands through the exotic plants growing in his garden.
