Trees of the Parks

The University Parks aren't just a beautiful green space for everyone to enjoy - we also host a nationally important collection of trees, working closely with our colleagues at the Oxford Botanic Garden and Arboretum. 

This is a landscape created by botanists, and you’ll find a wonderful diversity of trees. There are more than 1,900 trees from around 380 distinct taxa, from native British species like the 30+ varieties of hawthorn that line Thorn Walk to exotic specimens from every corner of the globe.

We've made a huge amount of information about these available on our Arboretum Explorer portal. You can use it to find out about any tree in the park, including its species, age, condition and size; you can also learn about the environmental benefits the trees in our care provide, including absorbing carbon and helping control flooding. 

The website features an interactive map that works well on mobile devices, so it's the perfect companion to a walk in the park – for example you can use it to find trees of a particular species or genus so you can plan a route to see them all. 

Please click on the map below to start exploring our trees. You can also discover more about some of the notable specimens and groups around the park below the map. Each tree listed has a tree code following it. To find this, type the tree code into the search box on the top left hand side of the tree map.

Coronation Clump 

This ring of trees, consisting mainly of chestnuts and maples was planted to commemorate the coronation of Queen Elizabeth II in 1953. It also includes a Coulter’s pine (Pinus coulteri), a native of the southwestern USA that produces the heaviest cones of any tree – up to 5kg each in its natural range. 

Diamond Jubilee Trees 

In 2013, the Curators of the University Parks invited each of the six Heads of Oxford University’s Permanent Private Halls to plant a tree to commemorate the Diamond Jubilee of Her Majesty Queen Elizabeth II. 

Six young tulip trees (Liriodendron tulipifera) (15950) were planted in a 20m circle. Their true beauty will not be seen for around 50 years when the trees will merge together. 

At the centre of the ring is a Magnolia 'Star Wars' (Magnolia lilliflora x M.campbellii) (15955). This was chosen because Liriodendron and Magnolia are in the same plant family (Magnoliiaceae). It flowers when young with pink and fragrant blossoms in April and May. It may be another decade or so before the tulip trees begin to produce flowers. 

Japanese Pagoda Tree (14302) West Walk

Styphnolobium japonicum, more commonly known as the Japanese pagoda tree, is native to China. This tree was planted in 1888 making it one of the oldest specimens in the Parks. In 1936 its girth was recorded as 6ft 6ins (1.98m), and in 2025 we measured it at 11ft 2ins (3.43m). It produces creamy yellow flowers in July which are the source of the transparent pigment Imperial Yellow. 

Tulip Tree and Bean Tree Avenue - South Walk

The tulip tree (Liriodendron tulipifera) (8805) produces striking yellow-green, tulip-shaped flowers which open in June and July. It’s a deciduous tree with striking yellow foliage, normally growing between 70 to 150 feet (21 to 46 metres), although the Parks’ thin soil means the specimens here are unlikely to reach such heights. 

The Indian bean tree (Catalpa bignonioides) (13380) has large heart-shaped deciduous leaves, showy, clustered flowers and long cigar-shaped fruit pods. Its white flower heads, splashed with orange and purple, appear in late summer. These are then followed by distinctive long black seed pods that remain throughout the winter. 

Wellingtonias (8586) - North Walk

The majority of the Parks’ majestic cluster of Wellingtonia trees (Sequoiadendron giganteum), were planted in the late 1880s, with the smallest being added to the group in 1972. You can see them at the western end of the park, near North Lodge. 

This species of tree is the world's largest living organism and includes some of the oldest living things on Earth. Based on ring count, the oldest known giant sequoia is 3,500 years old.  

Heights of 300 feet and diameters of 30 feet are not uncommon in its native setting of North California. The Parks’ thin soil means that most specimens of the trees here are unlikely to meet their full height potential. 

Croquet Lawn 

The Parks’ croquet lawn is for the exclusive use of the Croquet Club and is surrounded by trees planted in 1878. These trees were designed to screen the Observatory which, when built in 1874, was isolated in the middle of the Parks. It is now part of the Science Area. 

Zelkova carpinifolia ‘James Gordon’ – Caucasian elm (15621) - North Walk 

This tree is the tallest of its type in the country at more than 33m. Zelkovas belong to the same family as the native elm – a close look at the leaves of both will show the family likeness. Almost all mature Caucasian elms in Europe are thought to have originated from the same nursery in East London in 1760. 

Disease-resistant elms (15372) – Picked Mead 

This ring of seven trees planted in 2023 is made up of six different cultivated varieties that are resistant to Dutch elm disease and one closely related Japanese Zelkova (Z. serrata). Each of the elms has a different growth habit and represents the ingenuity of plant breeding. It is hoped that these trees will one day help support the rare white letter hairstreak butterfly (Satyrium w-album). 

Elms were once an important part of Oxford’s urban landscape before being wiped out by Dutch elm disease in the mid-20th century. We’re helping bring them back now that breeders have created disease-resistant varieties – for example, we included several young elms in the row of street trees we planted along South Parks Road in 2024, where we hope they’ll flourish for many years to come. 

Tetradium daniellii – Bee-bee tree (8791) - South Walk 

This fine tree, originally from Korea and China, produces 3-4mm scented white flowers in late summer. These are extremely popular with bees and butterflies, and are followed by dark red-purple fruit in autumn. 

Fagus sylvatica f. Pendula – Weeping beech (10904) – Lucas Walk 

First cultivated in 1836, this tree has wonderful cascading limbs that fall to the ground, layer themselves into the ground and go again, forming a soaring cathedral of drooping limbs to get lost in. 

Quercus coccinea – Scarlet oak (15909) – Riverside Walk and The Leys 

This tree was planted around 2015 having been originally introduced from Canada and the Eastern USA in 1691. Its flaming red autumn colour make it a spectacular seasonal attraction.
