Some species have deeply furrowed bark, called 'ironbark', as in A. Acacia bidwillii is one of several bipinnate-leaved species with corky bark. However, the majority of species have grey smooth or rough bark not likely to attract attention.

Acacias are divided into two major leaf types although there are other minor divisions. The majority of our acacias have what appear to be leaves. These are, in fact, flattened or modified leaf stems called "phyllodes" that have evolved to take the place of leaves and, by their construction, are believed to help minimise water loss in hot climates.

The other type has bipinnate or fern-like leaves such as A. Bipinnate-leaved species, it is understood, mostly occur in higher rainfall areas. If acacias are grown from seed, the first leaves to emerge are true leaves and, unless they are going to be bipinnate as adults, will soon develop phyllodes.

Several species maintain their true leaves until they are about one metre tall. You may have seen A. If you look closely at the phyllodes you will notice the venation differs in individuals; some have single central nerves, some have several nerves like A.

Some species, for example the northern A. There are many variations to be found. The majority of species have glands or extrafloral nectaries as they are sometimes called. I wonder if you have ever noticed them? Sometimes they are hard to find as they are embedded in the leafstalk or pulvinus. In others they are really conspicuous and usually occur along the top margin. Some like A. Others differ and there are several that have glands under the tip of the phyllode and one, A blakelyi in Western Australia, that has a gland on the central margin that makes it very easy to identify.

Acacia Tree When you have a piece of land and you want to create a garden with fast growing plants that give very good shade, it is very interesting to choose to plant an acacia tree.

They sprout from thorny or unarmed branches. Main species of Acacia We show you the three main species of this incredible genre: Acacia baileyana It is a shrub or evergreen tree native to Australia that reaches a height of between 3 and 10 meters known as mimosa or common mimosa.

Acacia dealbata It is an evergreen tree native to Australia and Tasmania that reaches a height of between 10 and 12 meters. If you would like to have an acacia in your garden, write down these tips: Location : outside, in full sun. I insist, plant it as far as you can from any construction and pipes to avoid problems in the future.

Soil : it is not demanding. It grows well in poor soils, even in those that have a tendency to erosion. Irrigation : during the first year you need at least one weekly irrigation, but from the second it is not necessary to water it. Subscriber : it is not necessary. Pests and diseases : they are very resistant. Transplant : in spring. Multiplication : Seeds: in spring. After the thermal shock that we explained before having them 1 second in boiling water and 24 hours in water at room temperature , you have to plant them in a pot with universal growing medium.

Cover them with a layer of earth so they are not directly exposed to the sun, and keep them watered. Do not put too many in the same container, because when you grow so fast it will be very difficult to separate them later.

Ideally, do not put more than 3 in a pot of Cuttings: in spring. Simply cut a piece of branch that measures at least 40cm, impregnate the base with rooting hormones and plant it in a pot with universal substrate mixed with pearlite in equal parts.

Keep it watered and in a place protected from the direct sun, and after a month it will emit the first roots. Leave it in that pot at least during that year; so it can be strengthened quickly. Pruning : it is not necessary. The cares are the following: Location : outside, in full sun. Watering : twice a week. Subscriber : in spring and summer with liquid fertilizers.
