Care and Growth of Drought-Tolerant Flowering Acacia Trees
There are many different types of acacia trees. Most are able to live off rainfall alone in southern California once they are established.
Flower color range from creamy white to bright yellow and sometimes in orange. Some trees are deciduous, some are evergreen.
Mine has grown to about 20 feet tall. It has beautiful silvery gray leaves on golden branches.
I planted this acacia because it is drought tolerant, will cover the back fence (and my neighbor) and they bloom! Look at these beautiful giant yellow flowers. They are actually lots of tiny puff balls which smell wonderful too.
I have heavy clay, alkaline soil and no water. So I was looking for something that fit into my little micro-climate and Acacia fit the bill — and it blooms in February!
This tree was planted about two years ago. The first year I gave it weekly regular watering, the second year, maybe once a month during summer, and now, I only have to give the tree a deep soak every few months.
When the whole tree is covered in big, bright yellow blooms they really stand our and are so beautiful! The blooms also smell heavenly. Bring a few branches indoors and try them in a tall vase for a dramatic arrangement.
Since the flowers are very small, they are attractive to beneficial insects like the tiny parasitic wasps that eat whiteflies, and the tiny native bees I see around. Bees like the blooms too, I’m glad to have them around.
