My Wild Olive in April 2012
This small, graceful,
evergreen tree, stretching its branches to the heavens as it flickers its
silvery-gray leaves in the light sunny breeze is a perfect specimen for any
garden. Olive trees have a timeless feel to them - young trees can look old,
while old trees still express an ageless, graceful beauty. They are among the
more long-lived species of trees and can reach a ripe old age of over 500
years. No wonder the ancients regarded the Olive tree as a manifestation of the
ever-present life-force: evergreen and long-lived, with a tenacious will to
survive against the odds in dry and inhospitable places.
2006
I planted mine at the
beginning of 2006 and since then it has just gone from strength to strength.
There was one year where I had trouble with a white, woolley infestation on the
leaves – presumably Mealy bugs (or woolly aphid), which are certainly the worst
and more common insect attack on plants. They can live on the plant or on
the roots in the soil and are capable of very rapidly killing large specimens.
Mealy bugs belongs - like
other scale insect - to the Coccoidea superfamily and
reproduce very rapidly laying their eggs underneath a cotton-like elliptical
covering so they can consequently attain large numbers and also quickly acquire
resistance to pesticides. They are small (about 1-3mm) and have a characteristic
loose, hairy and waxy cover used to build their nests (depending on the
species) and retain well-developed legs and thus remain mobile, even as adults,
unlike most other scale insects. This means that they can easily spread and infect neighbour plants.

The Wild Olive berry fruit is a favourite for fruit-eating birds, so look out for the Grey Lourie, Speckled and Red-faced Mousebirds, Redwinged and Pied Starlings, rameron and African Green Pigeon and the Blackeyed Bullbul. You may also see Vervet monkeys, Chacma baboon, mongoose and even Warthog and bushpig feeding on the fruit in the tree or on the ground.

The botanical name
indicates that this tree is an African variety similar to the one found in
Europe. This tree also has some medicinal value. The leaves may be used as a
substitute for tea. An infusion made from the bark relieves colic while an
infusion of the leaves is used as an eye-lotion for humans and cattle. A concoction of the leaves can be used as a gargle for a sore throat and
diphtheria. Powdered dry leaves can be used as a snuff to stop nosebleeds or to
stop other kinds of bleeding. A concoction of the roots taken mornings and
evenings alleviates kidney and bladder problems.
The hard, heavy and
beautiful golden-brown wood is used for furniture, ornaments, spoons and
durable fence posts. An ink is made from the juice of the fruit. The early Cape
settlers used the fruits to treat diarrhoea.
2010
It is easily propagated
from seed or from hardwood cuttings although I bought mine as a sapling. Sow
fresh seed in river sand and treat cuttings with a rooting hormone. The
slow-growing frost, drought and wind-resistant wild olive makes a good shade or
screen plant in the home garden, on golf courses and elsewhere. It is popular
for bonsai, street planting, and for use at schools, office complexes, and in
parks. It is perfect for dry areas where it is an excellent fodder plant for
stock and game and it has also been used to stabilize erosion dongas/ditches.
2011
Here in Gauteng the Wild Olive
is found on the southern slopes of the Magaliesberg mountain range – from
the rocky areas exposed to all the weather elements, in the kloofs, woodland
and down to the river bank areas of the Magalies River. If you should be
travelling in China, India, Arabia or on the Mascarene Islands, don’t be
surprised to see the Wild Olive there too!
