characteristics
Benefits
Notes
Acer
platanoides
Loose
soil
with
excellent
drainage.
Optimum pH: 5.5 - 7.
In
the
Italian
peninsula is mainly
mountainous species.
Low potential for
ozone
formation.
Good resistance to
air pollution.
It requires low
maintenance and it
has a good wind
resistance.
At low altitudes it
needs of never dry
areas and deep soils.
Acer
pseudoplatanus
Well-drained
soils,
both
acidic
and
alkaline.
In
the
medium-
Tyrrhenian
it
is
typical in moderate
climates within the
Apennines.
Low potential for
ozone formation.
Phytostabilization
action for Zn, Cd,
Pb e Na.
Acer lobelii
Fertile
soils
and
humid for most of the
year.
It is a species
typically Apennine.
Low potential for
ozone formation.
Endemic species of
southern Italy has
been
planted
successfully in some
Roman gardens.
Alnus cordata
It can grow on
various types of soil,
but in the Roman
climate never too dry.
Mesoigrophilous
species, more adapted
to summer drought
than
Alnus glutinosa
.
Good
naturalistic
functions.
Good
suckers
capacity.
It enriches soils.
Endemic species of
southern Italy.
Betula pendula
It is suitable both to
poor that with a deep
layer
of
organic
material soils, both in
rich water soils to
very drained soils. It
bears values of soil
pH up to 3.3.
Species
distinctly
heliophilous of cool
temperate climate.
Colonizing species
with good sprouting
ability (even root
suckers).
In
Italy
it
is
widespread,
especially
in
mountain
and
becomes rare in the
south.
Juglans regia
It needs of very fertile
and rich in nitrogen
soils; it does not like
firm ground.
Species
distinctly
heliophilous.
Fast growing in
juvenile stages.
Platanus
hybrida
It grows well on clay,
deep, rich in humus,
moist soils, but it’s
also adapted to rich in
nutrients anthrosols.
Heliophilous and well
adapted
to
Submediterrranean
and
Mediterranean
conditions.
Resistant
to
pollution
and
pruning.
Weatherproof.
Rapid growth in
juveniles stages.
Hybrid
between
Platanus
occidentalis
, North
america,
and
Platanus orientalis
,
widespread
in
southern
Europe.
Prone to infections
(
Macrocystis
fimbriata
). It can
cause allergies.
Populus
tremula
Indifferent to the pH
it can grow on very
poor soils and it is
less tied to moisture
than other
Populus
species.
Hygro-mesophilic
heliophilous species.
In the Tyrrhenian
coast is primarily a
species
of
the
mountain belt.
Pioneer
fast-
frowing species in
juveniles stages.
High capacity of
roots suckers.
This poplar species
is characterized by
the impossibility of
propagation
by
cuttings.
