Celebrating St. Fagans Victorian tree heritage

Autumn sends us an invitation to pause and admire the beautiful trees that surround us. It lays a vibrant carpet of colourful leaves welcoming us into the woods. In this once in a year spectacle, we advise that you wear comfortable shoes, take slower steps and mindfully redirect your gaze up to the sky to contemplate our magnificent trees. 

In St. Fagans National Museum of History, you can find some of the most beautiful specimens of trees planted by the Victorians and Edwardians that shaped our beautiful gardens. 

This year we celebrate the 150^th anniversary of the Fern-leaved Beech (Fagus sylvatica ‘Aspleniifolia’) located in the terraced gardens of the castle. This magnificent and unusual specimen was planted in 1872 under the head gardener William Lewis. This cultivar was introduced in the UK in the early 1800’s and won the RHS Award of Garden Merit in 2002. The leaves are dark green and deeply serrated, turning golden before falling in autumn. This specimen has an impressive dark and smooth trunk with its girth measuring 3.67m in diameter. The Fern-leaved Beech is a Chimera, originated from a plant cell mutation of the Common Beech (Fagus sylvatica). An interesting fact is that occasionally some of the serrated leaves revert to the Beech leaf shape, when that happens it is advisable to remove the reverted branches as they tend to grow more vigorously than the cultivar.

Another magnificent feature that celebrates 150 years in St. Fagans is the row of London and Oriental Planes planted by William Lewis along the formal ponds overlooking the terraced gardens.  The London plane is a natural hybrid of the Oriental Plane and the American Plane. The Oriental (Platanus orientalis) and London Plane (Platanus x acerifolia) are distinguishable by their leaf shape with the Oriental Plane having more deeply lobed leaves. Many London planes were planted over 200 years ago in the squares of London, hence its common name. This tree can withstand high levels of pollution and was one of the few trees that could thrive in the soot-laden atmosphere of cities before the passing of the Clean Air Act in 1956. Did you know that this resilient tree can store around 7.423 kg of Carbon at maturity? Large trees like this play an important role in improving air quality by sequestering carbon dioxide, removing air pollutants and absorbing gases that are harmful to human health.

William Lewis was also responsible for the planting of the Pine Walk in 1870. This beautiful avenue of Black Pine (Pinus nigra) and Scots Pine (Pinus sylvestris) guides you through the path towards the old Orchard. These tall and majestic trees enclose the space resembling the walls of a Cathedral. The bark of the Black Pine is dark grey with ridges and the needles are longer than other Pines. The Scots Pine is the only Pine native to Britain, it has shorter and compact needles and a warm red upper bark. Unfortunately, in recent years we have lost some of our Pine trees, in order to preserve this historic feature, we have planted four new Black Pines along the path. 

As we take pleasure in admiring these magnificent trees in the present, we must thank some of the far-sighted people of the past who have gifted us with this wonderful legacy. Trees make our cities a more pleasant and healthy environment. They enhance biodiversity, reduce flood risk, improve air quality, provide shade, and reduce the urban heat island effect in summer months. If you would like to leave a valuable legacy for future generations, start by planting a tree.
