False Acacia

Fascinating Facts about the False Acacia

The False Acacia is a tree that is native to the southeastern parts of the United States and it has been effectively introduced to other temperate regions in North America, Europe and Asia. This tree is also sometimes called the Black Locust and its scientific name is Robinia pseudoacacia. The tree is well known for its distinctive white pea-like flowers and is used as an ornamental tree in some places. The blossoms are aromatic and it is quick growing tree. The False Acacia has many interesting features.

This tree can grow as tall as seventy feet and has a large spread as the trunk of a mature tree can be 3-4 feet in diameter. The tree which is grown along the streets in many well-populated areas is known to handle pollution fairly well and this has made it a popular choice as an ornamental tree along busy streets. The False Acacia is also known as a honey producer and the form that is produced in France, called the acacia monofloral honey, is considered particularly noteworthy.  The tree starts to flower only after a time lag after becoming established, and the flowering period itself does not last very long. Also the honey production is not annual. Weather is said to be a factor on how much nectar the tree produces in a given period. This tree needs a lot of sunlight and is not likely to do well where it is crowded amidst other trees.

The other striking feature of the False Acacia is that it has very strong and durable wood, especially in contact with the ground, and is considered rot resistant. This makes it a great choice for fence posts and for boats and ships. The quality of the timber has made it a popular choice for shipbuilding and also for its use as a treenail to hold planks together. The quality of this wood is such that it hardens over time and this makes it a good choice for some kinds of building. One of the other uses of this wood is in wood-burning stoves. The False Acacia wood is slow burning and it produces very little smoke and further more the wood burns even when somewhat wet. This makes it a great combination for the stoves. If you are using it in the fireplace, make sure it has been treated while still young because otherwise the knots in the wood and beetle damage sometimes lead to the fire spitting our pieces and this can be dangerous.

The False Acacia is known to have nitrogen-fixing bacteria in its root system and this helps it adapt to all kinds of soil. This is one of the reasons that this particular species settles in and grows rapidly under varying conditions. This feature is now also making it a popular tree for managed forestry because where fertilizers are expensive and potentially intrusive in some ecosystems, introducing this tree can be a great way of regenerating the soil.

Among some of the dangers that this tree faces is locust borers. The branches and trunks are sometimes completely destroyed by this insect. The tree is also short-lived in nature because the wood is vulnerable to damage. So, while you can use it to create rapid shade and interest in a garden that is being established, you have to be prepared for the fact that the tree will not last very long. The quick growth of the tree can also make it seem invasive in a small space and it is worth considering this when picking a place for the False Acacia.
