About

A mountain botanic garden on the Cowal Peninsula, Argyll, managed by the Royal Botanic Garden Edinburgh. Spanning 120 acres within Loch Lomond and The Trossachs National Park, it features the famous Redwood Avenue of 49 giant sequoias (Sequoiadendron giganteum) planted in 1863, now reaching 50m in height - described as one of the finest entrances to any botanic garden in the world. The garden also holds extensive Himalayan, Chinese, Japanese, and North and South American plant collections with over 300 rhododendron species.

History

The Benmore Estate was bought in 1862 by Piers Patrick, who planted the Redwood Avenue of giant sequoias in 1863. The garden later became the Younger Botanic Garden and was gifted to the nation. It is now one of four regional gardens of the Royal Botanic Garden Edinburgh. The Redwood Avenue, now over 160 years old, remains the gardens most iconic feature.
