Hedges to line
garden walls
Cool your garden with a living green
wall by choosing a traditional shrub or select something unusual,
like a tall grass or edible plants, for your hedge. If you
have concrete block walls, a hedge will cool your garden significantly.
Traditional shrubs for hedges
Korean boxwood (Buxus
microphylla koreana) - slow growing to 2 1/2 feet high, this shrub
does well in a hot, dry climate. It can be sheared to a geometric
shape or left untrimmed and still be a tidy plant. The common
boxwood or English boxwood (Buxus sempervirens) does not do well in
desert conditions.

Pittosporum tobira 'Wheeler's Dwarf' grows at this
Photinia hedge's base.
|
Photinia (Photinia x fraseri)
- moderate to fast growing shrub to 10 feet high. Has reddish-bronze
leaves in Spring and white flower heads that can be as big a small
saucer. Sometimes suffers from lack of iron (chlorosis), which
results in yellowing leaves with green veins. Your nursery can advise about
treating this condition.
|

|
Indian Hawthorn (Raphiolepsis
indica) - perhaps best known as a low
mounding plant with dark green leaves and pretty pink blooms in the
spring. There are also taller varieties that grow to 5 or 6 feet
tall--and new choices seem to keep showing up every year. May need some
shelter from afternoon sun. Relatively low water usage.
|

There are varigated and dwarf varieties of myrtle. |
The evergreen Myrtle
(Myrtus communis) hedge takes care of itself. This shrub has fine
textured, bright green foliage that does not need much pruning
or trimming. This shrub has small white flowers and, later, blue-black
berries in the Fall. Low water usage and good drainage.
|

Except
for the dwarf varieties, Pittosporum gives off a heavenly fragrance
when it blooms in Spring. |
Pittosporum
(Pittosporum tobira), comes in dwarf, shrub
and tree forms, all of them evergreen The dwarf size is an excellent
foundation plant. The mid-size is ideal for a loose, rounded hedge. It does not need trimming.
The Pittosporum tree grows to 25 feet tall. Drought tolerant once established. |
A purple hedge

NOTE: There is another tree called the
Smoke Tree. It is tall and virtually leafless. Be sure you get the right one. |
Smoke Bush (Cotinus coggygria "Royal
Purple") - beautiful dark reddish purple leaves are the hallmark of
this small tree. Grows either as a multi-trunk shrub or a single
trunk tree to 15 feet high. The hybrid C. 'Grace' has blue-green leaves
and seed pods that appear to be large airy cloudlike
puffs of cotton candy. In Fall the leaves turn to orange and bright
red. A new introduction is the "Golden Spirit" variety, which has
brilliant golden yellow leaves. Low water usage for all three
varieties. |
The edible hedge
 |
The petals of the
Pinapple guava plant flower are tasty additions to a fruit
salad. And the ripe fruit in the Fall is delicious, too. |
Pineapple guava (Feijoa
sellowiana) - have your hedge and eat it too! You will often find
this South American native plant in nurseries as a small tree, but it can be a
multi-trunked shrub for an unusual and beautiful informal hedge. Soft gray-green leaves with very pretty
white blossoms in
the spring. And fruit to eat in the Fall. It may need some
shelter from full sun. Low to moderate water usage.
Natal plum (Carissa
macrocarpa) - another edible hedge, this one from South Africa. A fast growing upright
shrub with deep dark, leathery green leaves that can be clipped to a formal hedge. Blooms fragrantly
year 'round and produces small fruit with a cranberry-like taste.
Most natal plums are thorny but the 'Boxwood Beauty' variety is
thornless, as is the 'Tomlinson'.
The grassy hedge
|
Pampas grass (Cortaderia
selloana) - fast growing to 8 feet tall in one season with even
taller white or pale yellow "plumes". Cut back every
couple of years to 18 inches during January or it may end up 20
feet high. Leaves are toothy and will cut into skin so do not plant it near a
walkway.
|
|
Heavenly bamboo
(Nandina domestica) - looks like short bamboo but has brilliant yellow,
orange and reddish leaves. Can grow slowly to moderately to 6
feet. In the desert needs some shelter from blasting
sunlight. It may need treatment for iron-deficiency which turns
the leaves yellow with green veins. Very drought tolerant. |

Change
Just One Light Bulb in a Hallway.
Replace one 100 watt incandescent light bulb
with a 27 watt compact fluorescent light bulb and over the 4.5 year
lifespan of that one fluorescent bulb you will prevent 94 pounds of
additional greenhouse gases from going into the air. Over the
life of the light bulb you will save about $73 in energy and bulb
replacement costs.
