Leather Leaf
Acacia, (A. craspedocarpa) is an excellent,
descriptive name for this Australian native. Its common
name is an accurate description on the leaves, which are
oval shapes, thick and fairly stiff with a webbed
network of raised veins. To the touch the leaves are
course and brittle. In its native Australian habitat it
is an understory plant along with Cassias and Acacia
aneuras. In landscape settings its dense, upright
branches form an erect, compact head that make it an
ideal privacy screen or windbreak shrub. It can also be
used as a background or foundation plant or as
individual specimens. Mature plants may reach 9' to 12'
and be 6' to 8' wide. It is used primarily as a large
shrub or small tree in southwestern landscape designs
where it can be planted closely to form a dense hedge or
as individual specimens or small groupings. Tree forms
can be achieved with proper pruning that exposes the
branching pattern beneath the otherwise dense foliar
canopy.
In spring
individual, small, bright yellow, elongated rod flowers
are produced. Tan-colored, flat, 2" long pods develop
from the flowers. The botanical name probably is drawn
from a description of these pods since crasped
translates to broad in latin and carp refers to
fruit. Leather Leaf Acacia is moderately cold hardy (15
to 20 F) and grows well in full and partial sun. It will
tolerate a variety of soils but does best in
well-draining soils.
Established plants
are highly adapted to harsh summer conditions and can
survive without supplemental irrigation. Watering once a
month will ensure limited growth but more frequent
irrigation is needed to achieve optimal growth,
appearance and flowering. This plant grows slowly and in
some landscape applications it may be desirable to
install larger container sizes (15 gallon to 36" box) to
get more immediate impact.
Specimens pruned
into tree form can be used as individual specimens or in
small groupings. Leather Leaf are most commonly uses an
as informal hedge planting or as part of a landscape
screen. Because the growth of established specimens can
be easily regulated by irrigation practices, A.
craspedocarpa offers a low maintenance alternative to
Oleanders or other non-desert species used as landscape
screens.
