Empress Tree Care

Even if you are an expert at finding and removing escaping seedlings, the empress tree is not the ideal choice for your home, the surrounding area, or the ecosystems in the area.

The tree initially has a fragrant aroma that is somewhat vanilla-like. Between late April and early May, it is additionally ornamented with hundreds of blooms in the form of foxgloves.

The tree’s biggest disadvantage is that it appears to be advantageous. A single tree may be able to produce 2,000,000 seeds in a single year because the fruits on those blossoms have 2,000 seeds each.

The empress trees have a one-year growth rate of 20 feet. The likelihood that the tree will become an invasive species is very high, and if you do not remove an escaping seedling, it will pose a serious threat to the landscape.

Why you should never plant an empress tree?

The empress tree is a fast-growing, invasive species that is native to Asia. In its native habitat, the empress tree is kept in check by natural predators and diseases.

However, in North America, the empress tree has no natural enemies, allowing it to spread rapidly. The empress tree can grow up to 10 feet in a single year, and it produces between 5 and 20 million seeds annually.

Empress trees are often planted as ornamental trees, but they quickly become a nuisance. The roots of the empress tree are very aggressive, and they can easily damage sewer lines, sidewalks, and driveways.

Moreover, the seeds of the empress tree are spread by birds, making it difficult to control its spread. For these reasons, it is best to avoid planting an empress tree on your property.
