Seeking out new seeds, plants and trees is the order of the day in this week's Real Gardens. Ann-Marie revisits Lisa Jacobson, and the pair travel to the Royal Horticultural Society's Westminster Show in a quest for hardy modern plants for Lisa's borders. Carol Klein returns to the steeply sloping Devon garden of police officers Adrian and Debbie Taylor, concentrating on their 'orchard' boasting only three sad looking fruit trees. Together they head for a nursery looking for fruit trees which will ensure a bountiful crop. Monty Don goes back to Norfolk to see Bryony and Martin Jacklin, where Bryony is transforming what was once farmer's fields into a formal family garden. They plant wildflower plugs and seed mix into the lawn, and lend a hand to daughter Freya's clearing of her herb garden of 'weedlings and Seedlings'.
