This week's programme is bursting with seasonal greenery. Award-winning writer and RHS blogger Graham Rice explains how to grow a Yuletide favourite and one of our most mysterious native plants – mistletoe. Then we hop 'over the pond' for the latest in our Hidden Horticulturists series to explore the life of one of the 20th century's greatest botanists: holly expert Dr Shiu-Ying Hu. Meanwhile back at RHS Garden Wisley, Verity Batyll describes her favourite plants to brighten up winter gardens, and Devon-based food writer Mark Diacono shares his personal recipe for a delicious homegrown lemon verbena cocktail.
