Pick of the Day: Gardeners' World
8:30pm, BBC2
As summer unfolds at Longmeadow, Monty Don tends his vegetable garden and flowerbeds.
Meanwhile Carol Klein enjoys one of our unsung native flowers, the geum, which provides a splash of colour before other early summer blooms emerge, and visits a cottage garden that holds the national collection of cultivated forms.
Also Formula 1 veteran Sir Frank Williams tells us why he is opening his garden in Berkshire as part of a national festival weekend. With Rachel de Thame.
