Welcome to our garden website. Llwyngarreg is a 4 acre garden in West Wales, right on the Carmarthenshire and Pembrokeshire border. It was started by Liz and Paul O’Neill in 2000 and joined the National Garden Scheme in 2006.
We open ONLY for this charity, and are open on most days. To avoid disappointment, please check our phone message on: 01994 240717 . For group bookings, email
Our objective has been to create the right niches to grow the plants we admire and to try to do so in an aesthetically pleasing way. We grow a lot of plants which should do well in wet, mild, West Wales; Rhododendron, Acer, Primula, Bamboos, blue Meconopsis, Magnolia and some which have been a surprise: Dierama, Agapanthus, Tigridia, and Colocasia. We have grown a lot of plants (including many trees) from seed and continue to do so.
If you visit please do not expect to see a completed garden; it will never be finished! We enjoy making quirky structures, some out of living willow, which children can enjoy.
Wildlife has increased immeasurably as the garden has developed, most of it welcome, some merely tolerated! The bird and insect life thrives. There is the sound of running water and occasional chimes.
