The Garden Landscape Guide

National Botanic Garden of Wales

The National Botanic Garden of Wales opened in May 2000 and was the first botanic garden of the new Millennium. It is built in 568 acres of Regency parkland. The Great Glasshouse (which you can see on the satellite image if you zoom in on the map below) is an impressive piece of architecture and the largest single span glasshouse in the world. It contains zoned collections of some of the most endangered plants from Australia, California, The Canary Islands, Chilie, The Mediterranean Basin and South Africa. The unique and historic Double Walled garden traces the evolution of flowering plants. The garden boasts the longest herbaceous border in Europe. There is also a bog garden, bee garden and children's farm.

Head Gardener's Comment

The Great Glasshouse – poised in the landscape like a giant raindrop - is home to some of the most endangered plants on the planet from six Mediterranean climate regions – Western Australia, Chile, the Canaries, California, southern Africa, and the Mediterranean basin. It helps protect and conserve what is considered to be the best collection of its kind in the world. For those with more exotic tastes, the Tropical House – which opened in the summer of 2007 – is bursting with palms and pineapples, coconuts cardamom and scores of orchids. There is a unique and historic double-walled garden; lakes, ponds and walks; a theatre; licensed restaurant; shop; gallery; bog garden and bee garden; Physicians of Myddfai Exhibition and Apothecaries’ Garden; children’s play area,discovery centre and much more.


The Garden lies on land that was once a magnificent Regency water park and many of the original features have been restored. Many new features have been created and care has been taken that these not only harmonise with the historic landscape but add a sense of awe.

Plants of note

A plethora of plants will be found throughout this magnificent Garden. The Grevillea macutcheoni plant can be seen in the Great Glasshouse. It was discovered by a farmer about 10 years ago on a spoil heap at a property in Perth. He did not recognise the plant and sent a sample to King's Park & Botanic Garden in Perth for identification. Cuttings were distributed to Botanic Gardens throughout the world and have not been seen outside a protected environment since.

    I had wanted to visit the garden from many years but to be honest found it quite disappointing. The great glass house is more impressive from the outside. The gardens are quite disjointed with vast areas of mown grass and wide grey tarmac paths all a bit lack lustre and not well maintained. There were also sculptures mounted on piles of concrete blocks that do not add to the place.
    The planting was quite well labelled and the Bee garden and Japanese garden was interesting.
    The gardens are very close to Aberglasney gardens and they are magnificent

    I visited on a really drizzly, grey day and was astounded by what I found in the giant Glasshouse - it really cheered me up. For once I could beat the elements in Britain and enjoy the plants without getting soaked!
    Of course, I would have enjoyed the exterior gardens more in the sunshine, but at least I got to see fabulous plants inside and I would thoroughly recommend this as a great day out, come rain or shine.

    I'm sure the plants are first class but I found it all a bit sterile. The great glass house looks lovely but on a grey day I kept thinking enough green give me FLOWERS!!

    That said the walled garden was quite attractive.

    Highlight for me were the young Sparrows making a home in the great glass house!
