PROBABLY Britain’s best-loved garden – certainly the first whose popularity forced the introduction of timed admission – Sissinghurst, in Kent, was created by the poet Vita Sackville West, pictured right, and her husband Harold Nicolson.

Their grandson, Adam, now lives there as a tenant of the National Trust, with whom his ideas of the estate’s future sometimes clash. The conflict comes down to: is Sissinghurst a museum or does it move forward? Thoughtfully explored by Nicolson, this tension gives a dynamic twist to what is also an absorbing portrait of Sissinghurst and its passionate creators.
