The land that became Bute Park was previously the private estate of the Marquises of Bute, who acquired Cardiff Castle and its grounds in the mid-18th century. The first Marquis employed Capability Brown to landscape the Castle Green, and it is possible that London plane trees, some of which still stand near the Blackfriars site, were planted at this time. The grounds were re-landscaped at the end of the 19th century by the Head Gardener to the third Marquis, Andrew Pettigrew, who planted the avenues of Limes and Pines seen in the present day park, as well as circular beds featuring Turkey oaks surrounded by ornamental shrubs.
After the Bute family gave the park to the City of Cardiff in 1947, many ornamental and rare trees were planted under the direction of William Nelmes senior, the Director of Parks at the time. Nelmes planted collections of Acer, Crataegus (Thorns), Birches, Elms and ornamental Apples, as well as other unusual species. In the late 1980s further extensive planting was initiated by the City's Arboricultural Officer, Malcolm Frazer, adding to the range of species and renewing some of the earlier plantings. Among the newer collections are Oak, Ash, Hornbeam, Lime and Alder.
Bute Park has now more champion trees than any other municipal park in Britain, and the Bute Park Arboretum contains over 3,000 individually catalogued specimens. The arboretum section of the Bute Park website has further details. The park also has a splendid avenue of Ginkgo bilobas leading from the Castle to the Mews which is now the Anthony Hopkins Centre of the Royal Welsh College of Music and Drama..
There have been three tree numbering schemes in Bute Park. The most recent survey, carried out by Owen Johnson on behalf of the Tree Register, uses small aluminium disks upon which four-digit numbers are stamped. These numbers are in current use and are included in the table below. Previously some trees received orange plastic tags as part of a pre-lottery bid survey. Trees planted by Malcolm Frazer from 1988 onwards have a three-digit number engraved on a small plate to identify them. Where relevant these are listed as "Old tag" in the information about each tree.
The following table includes all current Great Britain and Ireland Champion trees. A significant number of the Wales Champions and some Glamorgan Champions are also included.
A separate detailed list of the trees alongside the River Taff and the Herbaceous Border has been compiled and is available as a pdf.
A location map has been provided to assist in finding the trees.
