TREES IN THE PARK

Since 1953 Headington Hill Park has been maintained as an arboretum, and as a public park with many new trees added. Many of the original trees survive. Of the approximately 1,000 trees within the park, the Friends have compiled a walk highlighting a few of the most interesting, old and rare species.

5) Butternut – (Jugans cinerea) – Sometimes known as the White Walnut. Very rare in the UK, this
is an old and large specimen, 22 meters high with a spread of 34 meters. This tree is listed as one of
the “Monumental Trees of England”. – It originates from the eastern USA and Canada where it is
listed as “endangered”. The nut matures in mid autumn. The bark and nut rinds were once used to
dye homespun cloth. During the American Civil War the Confederate soldiers were known as
“butternuts” because their uniforms were coloured with butternut dye.

a previously fallen tree. It is a native of China, with one of the largest leaves found in the UK, The
tree produces violet foxglove like flowers in May. A tradition in Japan is that a tree is planted at the
birth of a girl this fast-growing tree matures as she does. When she is eligible for marriage the tree
is cut down and carved into wooden articles for her dowry.
7) Nettle Tree or Honeyberry – (Celtis australis) – A group of 3 – It is confined to collections, and
related to the Elm. Originally from Southern Europe.and introduced into England in 1796. The fruit
of this tree is much loved by birds and other wildlife. It is supposed to have been the “Lotus” fruit
of the ancients. In the 8th century BC, Homer has Ulysses refer to the “Lotus-eaters” and the “lotus”

English Oak8) English Oak

8) English Oak – (Quercus robur) – A large and splendid tree with a spread of over 30 meters, and
has a girth of 3.7 meters. This tree is of great age,(approx 150 years,) and is certainly one of the first
trees planted in the arboretum when the Hall was built. It supports the highest biodiversity of insect
herbivores, small mammals and birds of any British plant. The Oak is the national tree of England.

13) Black Birch – (Betula nigra) – This is a rare species originating from the Eastern USA.. The
attractive bark is variable, usually being dark grey-brown to pinkish-brown and scaly. The fruit is
unusual among birches as in matures in late spring. It is composed of numerous tiny winged seeds
packed between the catkin bracts. Native Americans used the boiled sap as a sweetener similar to
maple syrup.
15) Pride of India or Golden Rain Tree – (Koelreuteria paniculata) – Native of eastern Asia, and
introduced from China in the 1760s. Unusual foliage with small panicles of yellow flowers,
followed by papery bladder like seed pods ripening to pink in the autumn.
16) Japanese Bitter Orange – (Poncirus trifoliate) – This tree is rare with only a few in the UK.
Unusually it is a hardy member of the orange family, armed with large spines, lovely white scented
flowers followed by small “bitter” oranges in the autumn (not edible). Studies have shown that
Poncirus trifoliata contains “aurapten” at a high concentration, which is one of the functional
components having immunity against “citrus tristeza virus” (CTV), which is responsible for the
demise of millions of citrus trees.
