Theacacia is a tree or shrub from the Fabaceae family, from the Mimosoid subfamily. The acacia flowers are very regular, and often grouped in globular heads. They are generally yellow, even if certain species give a pink or white acacia flower (in particular the famous Robinia false acacia, tree that is often called acacia for abuse of language). The acacia tree has branches covered with very large and very pointed spines; certain species of birds and animals also like to come and nest in acacias, because its thorns protect them from other predators.
There are over 1,500 acacia species, of which 1,000 are visible only in one country, Australia, which has made it its national flower. Among the best known species, there is the Acacia Acinacea or the Acacia Myrtifolia.
The acacia is a very popular shrub in dry and arid countries, because it offers a little shade in the desert landscapes ... but also of consumable fruits and flowers. Acacia is found on almost all continents in different forms, which adapt to the climate where the tree grows. In the South of France, there is a variety of acacia very well known and appreciated for its pretty yellow flowers and its most pleasant fragrance: Acacia Fimbriatae, better known by the name of mimosa.
Use of acacia
Mainly used for its flowers, the acacia is a tree which also produces gum. It can also be used to produce firewood, building materials or even furniture because it is very resistant.
In pastry, acacia flowers wild are used for the preparation of donuts or other pastries which they pleasantly flavor.
Warning: if the Acacia honey is renowned for its delicious taste, the latter actually enjoys a wrong name. Indeed, acacia honey is honey made from the flowers of the false acacia locust; for more accuracy, this honey should therefore be called locust honey!
The period of acacia plantation depends on its species: some must be planted between the end of October and the end of March, others between September and May, and some can even be planted all year round.
If the acacia flowers throughout the year, its most important flowering period is, however, spring. Acacia is an easy tree to grow, it does not need a particularly rich soil; the latter must however always be well drained so that the tree can flourish properly. On the other hand, it needs the sun and would not tolerate too shady surroundings.
Acacia is a tree that reproduces very quickly and spreads quickly, so it is wise to contain its roots as soon as it is planted ... or to plan an isolated plantation where its roots can spread out as they please.
Acacia cultivation and care
Very easy to grow, acacias are undemanding and require little maintenance. They simply need heat (you must maintain a temperature of 15 ° C minimum during the day and 7 ° C at night), even if they can be relatively resistant to cold and drafts.
Diseases and parasites of acacia
If acacias are disease-resistant trees, they can be preyed on by aphids when spring arrives.
