1.1 Species Selection
By taking into account the issues identified in
Section 5. Street Tree Considerations of the
Street Tree Strategy, 52 species of trees have
been identified to allow street tree planting in most
situations.
The following descriptions of each tree provides
vital information on their characteristics and
requirements, including scientific and common
names, growth rates, maintenance requirements,
soil, microclimate requirements and constraints for
use such as power lines.
The descriptions and data should be used as a
guide only especially the suggested Ultimate
Height and Ultimate Spread. This data in
particular is a guide to the mature size of the tree
in optimal street planting conditions. This
obviously varies from site to site.
1.2 Species Descriptions
The descriptions are categorised under the
following headings:

General Description
Common Name: Is the name by which the tree is
commonly known by in the South Australian
nursery industry.
Provenance: Where the tree originates from.
Three options are provided – Indigenous (found
originally in the Adelaide environs), Native
(originally found somewhere in Australia) and
Exotic (originates from a country other than
Australia). The descriptor will also indicate habitat
/ biodiversity value where appropriate.
Ultimate Height: Optimum height in perfect urban
conditions.
Ultimate Spread: Optimum spread in perfect
urban conditions.
Growth Rate: The rate at which the tree grow to
achieve its mature size and form. Three options
are provided – Fast, Medium and Slow.
7. STREET TREE STRATEGY – Species List
1. Species List
Habit / Form: The shape and habit that the tree
commonly exhibits e.g. pyramidal, columnar,
rounded canopy etc.
Soil: Indicates trees preference to certain soil
conditions and pH.
Longevity: Estimated average life. Three options
are provided: Average (25-50 years), Long (50100 years) and Very Long (Greater than 100
years).
Tolerances: Indicates the ability of the tree to
withstand certain conditions including frost, wind,
coastal exposure, pruning, Water Sensitive Urban
Design (WSUD) etc.
Services: Indicates suitability around services
such as sewer and power-lines. Description will
also identify if the particular tree has been
approved by ETSA and/or SA Water. The City of
Marion is seeking to gain formal approval from the
service companies where a tree has been
suggested that it is suitable for planting under
power-lines or near underground services without
being on their general list.
Maintenance Considerations: Indicates
maintenance requirements such as formative
pruning, need for root barriers etc.
General Description: Provides a general
description of the tree including flowering colour
and times and other ornamental features.

native deciduous or partially deciduous trees that
therefore produces some leaf litter. Flowers and
seed pods also produce a reasonable amount of
litter.
General Description: A great feature tree, perfect
to highlight gateways or important locations where
there is enough space so that the seed pod litter
issue does not cause major problems. Generally
symmetrical, pyramidal tree with large palmate,
glossy leaves and brilliant scarlet, waxy bell flowers
on scarlet stalks that appear in November or
December.

Tolerances: Recognised for its ability to grow in
difficult conditions and locations.
http://www.anbg.gov.au/callistemon/index.html
Services: ETSA approved under power-lines.
Maintenance Considerations: Some susceptibility
to splitting in mature years. Although a relatively
small tree, a root barrier is beneficial to protect
infrastructure.
General Description: Harkness has long, stiff,
slightly weeping, grey-green leaves and deeply
fissured , dark grey bark. A long lasting, profuse
display of crimson-red bottlebrushes up to 20cm
long appear in late spring, early summer. Well
suited to difficult, narrow sites. Flowers tend to
attract a number of bees – this should be
considered when determining location.

Celtis australis
Celtis australis
Common Name: European Hackberry or Nettle
Tree
Provenance: Exotic
Ultimate Spread: 6m
Growth Rate: Fast
Habit / Form: Clear trunk, rounded canopy
Soil: Most soils.
http://www.istrianet.org/istria/flora/fruit-nuts/celtisaustralis_hackberry1.htm
Tolerances: Suitable for difficult conditions and
locations. Very high pollution tolerance.
Maintenance Considerations: Very hardy once
established with no major maintenance problems.
Due to weed potential of the genus, this tree is only
to be used north of Seacombe Road and also
where stormwater is not directed into wetlands or
Water Sensitive Urban Design (WSUD) situations.

Corymbia eximia ‘Nana’
Corymbia eximia ‘Nana’
Common Name: Yellow Bloodwood
Provenance: Native
Ultimate Height: 8m
Ultimate Spread: 6m
Growth Rate: Medium
Habit / Form: Rounded canopy, typically with a
crooked trunk.
Soil: Well suited to most soils, including poor
gravely or sandy soils.
http://www.metrotrees.com.au/treehandbook/pagelistings/corymbia-eucalyptus-eximia.html
including drought. Slight discolouration of leaves
occur due to frost damage, although this fades
during warmer weather.
Services: The cultivar ‘Nana’ is suitable under
power-lines.
Maintenance Considerations: Minor formative
pruning required to attain desired canopy and single
trunk.
General Description: Patchy grey crooked trunk
with broad lanceolate leaves forming a rounded,
often open, canopy. A mass of creamy flowers
appear in spring, normally from August to October.
17
Corymbia ficifolia
Corymbia ficifolia
Common Name: Red Flowering Gum
Provenance: Native
Ultimate Spread: 5m
Growth Rate: Medium
Habit / Form: Compact round tree on a large trunk.
Soil: Most soils but will show die-back in
waterlogged soils.
http://asgap.org.au/c-fic.html
although prefers ample room due to large trunk
(lignotuber) and non-compacted sites.
Maintenance Considerations: Requires formative
pruning to ensure strong branch structure. Large
fruits (nuts) generally remain on the tree and do not
cause a significant litter problem.
General Description: A variable upright tree with
light grey, red-brown fibrous bark. Dark green
leaves with large showy flowers ranging from cream
to red. A number of grafted varieties are available
but the graft success is difficult to determine due to
the relatively short period of time that they have
been produced. It has been indicated that such
graft failure may lead to mature trees breaking off at
the graft which in a streetscape situation is
obviously not satisfactory.

Tolerances: Most conditions and locations but
prefers ample room, non-compacted and exposed
metre in height. Very tolerant of drought conditions
and air pollution such as vehicle emissions.
maintenance issues. Does not have the limb-drop
problem that the Lemon-Scented Gum has.
General Description: Known for its mottled,
spotted trunk and graceful foliage, this large tree
makes it an ideal choice where space is available
and to create a dramatic avenue effect. Used with
great success along medians of main roads in
Marion.

sites. Suited to WSUD situations.
http://cals.arizona.edu/pima/gardening/aridplants/Eucalyptus_
camaldulensis.html
Services: Not under power-lines or near other
services.
Maintenance Considerations: Is known for limb
drop once tree reaches maturity. Careful positioning
and site planning will minimise this issue.
General Description: This magnificent large tree
has strong Kaurna significance. It is best known for
the manufacture of shields from the bark of the tree.
Many examples of this ancient cultural practice can
still be seen on River Red Gum ‘scar’ trees around
Marion.
http://www.metrotrees.com.au/treehandbook/pagelistings/eucalyptus-camaldulensis.html
The River Red Gum will grow to become a large,
broad spreading tree with striped bark patches,
ranging from pale grey to charcoal and occasionally
pink. The leaves are relatively short and narrow but
have the typical “gum leaf” look. The small flowers
are small but profuse with the fruits (gum nuts) that
follow also being relatively small.
This tree should only be planted in suitably
large locations with access to water. They make
an excellent feature/gateway statement.
Approval to be sort from Council for their
planting due to their eventual size and potential
impact.
