About the garden

Owned by

Cared for by the National Trust

Designed By
Thomas Mawson

A peaceful oasis on the outskirts of Cardiff, Dyffryn has something new to discover on every visit, from intricate themed garden rooms to sweeping formal lawns and productive kitchen gardens to a large arboretum. The gardens host a number of different styles inspired by countries from all over the world, from a recognisable Italian influence in the Pompeiian Garden to the rainforest-like quality of the plants in the Exotics Garden. With a café, shop and second-hand bookshop, there is a lot to see and do on a visit to Dyffryn.

These Grade I-listed gardens are the product of a partnership between prominent garden designer, Thomas Mawson, and passionate horticulturalist and owner, Reginald Cory. In our work today we are building on Mawson and Cory’s spirit of tradition and experimentation in our approach to restoring the gardens. Our aim is not to achieve an exact historical recreation but rather to hold the historical Edwardian roots at the heart of what we do and using new and innovative ways to make it work for the future, such as gardening with biodiversity and climate change in mind.

Within the gardens is Dyffryn House, a grand Victorian mansion, currently closed to the public as it undergoes serious restoration work. Just 20 minutes from the centre of Cardiff, Dyffryn is full of secret spaces and horticultural surprises as well as free parking, a café, a shop and two play areas. 

Please see our website for more information and seasonal events.

Please note: this garden is partially accessible.
