The Cook family has farmed this valley for 6 generations. Over this time they owned four farms – now it’s just two, Highfields Farm and Penwern Farm, owned by Jenny’s cousin Lynne. The family also provided the vicars for two local churches – St Illtyd, Mamhilad and St Michael, Llanvihangel Pontymoile. After running as a commercial enterprise for many years, they now open the garden as part of the National Gardens Scheme  raising money for cancer charities.

Thae garden has been featured on gardener's world and in many gardening periodicals.
