Most popular Acacia species for gardens

If you are looking for trees that resist drought without problems and that are almost completely covered with flowers during the spring, then I encourage you to put one or more Acacia trees in your garden. These trees have a fairly fast growth rate, in addition, they have evergreen leaves, so you will not have to rake very often, since they are not very dirty plants.

Yes it is true that when the flowering season ends, the ground ends up full of small yellow petals, but that can even be pretty; and, in any case, if it is near the pool, they can be removed with the net. Would you like to know which are the most popular Acacia species for gardens and what are their characteristics? Let’s go there.
