The land that became Bute Park was previously the private estate of the Marquises of Bute. The first collection of trees was planted by Andrew Pettigrew, Head Gardener to the third Marquis, and included big avenues of Limes and Pines. 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.
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 lists all current Great Britain and Ireland Champion trees, and some former champions. A few of the Wales Champions and some other notable trees are also included.
A location map has been provided to assist in finding the trees.
