The collaboration

The National Trust look after the greatest collection of historic gardens and garden plants under single ownership in Europe. They encompass more than 500 years of history and a vast range of garden styles and fashions. With more than 200 gardens in their care, from kitchen gardens to colourful displays of spring bulbs, rare and unusual trees, along with heritage rose gardens, the National Trust bring a shared passion for gardening to this collaboration

The collaboration between Blue Diamond and the Trust working together has resulted in the development of unique collections of seeds, bulbs, roses and plants that are inspired by the gardens the National Trust cares for. These collections are available exclusively in all Blue Diamond Garden Centres and online at


A shared passion

Alongside a shared passion for gardens, both Blue Diamond and the National Trust are committed to caring for the environment - the National Trust is Europe’s largest conservation charity and this ethos flows through everything it does. 

Blue Diamond has taken many positive steps to reduce its impact on the environment and has implemented measures to reduce its carbon footprint. As part of Blue Diamond’s commitment to sustainable product production, all plants in the National Trust Collections by Blue Diamond are potted in peat free compost and in recycled and recyclable pots. In 2021, Blue Diamond also partnered with the Soil Association and is working with them to promote environmentally friendly and organic gardening.

'Preserved our heritage'

Michaela Davies, Brand Licensing Manager at the National Trust said: “We know that not only do our visitors love to explore the gardens we care for, but they also leave inspired to make changes in their own green spaces – however large or small. Therefore, this collaboration with Blue Diamond is a very logical one.

With both organisations also sharing a commitment to sustainable product production and featuring heritage, rare and unusual varieties; varieties that would have been lost without the National Trust’s care. This is a wonderful collection for both passionate gardeners and those just dipping their toes.”

Alan Roper, Managing Director of the Blue Diamond Group said: “The National Trust is a much loved and cherished institution and I am pleased that our collaboration with the National Trust will provide funding for this charitable organisation who for the past 128 years have preserved our heritage and open spaces for all to enjoy. I look forward to unlocking their rich heritage of plant species which will be grown on our nursery, and be on sale over the coming years within our garden centres.”

Already in 2023, Blue Diamond was able to offer to the public in an exclusive auction, 10 rare saplings, direct descendants of the apple tree that is said to have inspired Sir Isaac Newton’s theory of gravity. The public has not previously been able to bid for such rare saplings.

It is hoped that Blue Diamond, working with the National Trust, can bring more plants such as this, into commercial production.

Newton's Apple Tree Auction

Newton's Apple Tree Auction

Saplings from Sir Isaac Newton Tree with Gravitas auctioned off to a school, descendant of Sir Isaac Newton and a Woolsthorpe Manor neighbour.

Europe’s largest conservation charity, the National Trust and Blue Diamond Garden Centres auctioned ten saplings propagated from the apple tree that inspired Sir Isaac Newton’s theory of gravity.

At a presentation ceremony, held in September 2023 at Woolsthorpe Manor, the childhood home of Sir Isaac Newton and where he formed the Theory of Gravity, the 10 winners were presented with their saplings.

Amongst the winners, is a distant descendant of Sir Isaac Newton, a local Lincolnshire resident who lives only 10 miles from Woolsthorpe Manor and the newly built Science, Technology and Research Centre at Haileybury College in Hertford. 

National Trust Tree and Hedgerow Collection

National Trust Tree and Hedgerow Collection

As part of our collaboration with the National Trust, Blue Diamond has introduced a range of trees and shrubs suitable for hedgerows. 

Trees and hedgerows are nature’s highways and are essential for providing wildlife with places to nest and feed.
Following World War Two, the UK saw a decline in the number of its hedgerows and many that survive are in poor condition. It is therefore vital to address this and encourage people to plant hedgerows which will, in turn, encourage more wildlife.

Trees and shrubs, such as viburnum, hawthorn and elderberry, form part of the collection.
