Plane trees of London

Planes - other types

Index page

This page lists and briefly describes some named distinct forms that do not appear to be in cultivation in London.


Platanus x acerifolia 'Bloodgood'

This tree is offered for sale in the US. It is said to be particularly resistant to plane tree anthracnose.

Platanus x acerifolia 'Cantabrigensis'

This plant, which as far as I know is represented by one labelled specimen tree at the Cambridge Botanic Garden (in the group with the other planes), does not appear to be significantly distinct from other forms of P. x acerifolia.

Platanus x acerifolia 'Columbia'

An US raised variety (Frank Santamour, 1968/1970), which was raised from a deliberate cross between the oriental and western planes. It is said to be resistant to anthracnose diseases.

Platanus 'Alphen's Globe'

A smaller form with a globular crown. This is commercially available in continental Europe.

Platanus 'Autumn Glory'

This cultivar is known for its distinct purplish colour in later summer and autumn. It is available in continental Europe.

Platanus kerrii

This species is from Indochina. It is placed in separate subsection of the genus from all the other planes. The most noticeable distinction is its entire, pinnately veined leaves. Presumably, as a tropical species, no attempt has ever been made to cultivate it in Britain.

The following information is taken from Flora of China "described from Laos and also recorded from several places in N. Vietnam"..."the stipules are very small, the petiole base does not encloes the axillary bud, the leaf blade is long elliptic and pinnately veined, with an entire margin, and the fruiting branchlets each have 8-12 rather small infructescences."

Platanus lindeniana

A Mexican species.

Platanus orientalis 'Cuneata'

The status of this form is not clear, and the name is invalid according to Bean. It may well be a synonym of P. orientalis 'Digitata'. A plant is however offered under this name by some nurseries in Britain.

Platanus orientalis 'Liquidambarifolia'

This tree is available from some nurseries.

Platanus orientalis 'Mirkovec'

This is said to be a slow growing or dwarf form with bronzy foliage. The European Garden Flora lists this cultivar as a form of P. x acerifolia, the Plant Finder as a cultivar of P. orientalis.

Platanus racemosa

This tree is a native of Baja California and upper California. It is closely related to P. wrightii. It has not proved hardy in the UK, and is known to be seriously affected by anthracnose in cool climates.

Platanus 'Tremonia'

This tree is commercially available in the UK. I am not aware of any sites where it can be seen in London. It is described as an upright or fastigiate form.

There are occasional trees to be seen in London with a more or less upright or fastigiate form.

Platanus wrightii

(Platanus racemosa var. wrightii)

Another American / Mexican species that has proved difficult to grow here. Since, like P. racemosa, it has been given a H5 rating for hardiness by the European Garden Flora, it should be possible to grow it in sheltered parts of southern England; unless it is affected by other factors such as disease, as with P. occidentalis.

Platanus occidentalis 'Howard'

A gold foliaged form), cultivated in the United States.

Platanus x acerifolia 'Yarwood'

In cultivation in the US.
