History of the Empress
A sacred tree
The Empress Splendor (Paulownia) is a sacred tree of the Orient, long revered for its fast growth, quality wood and uses in traditional Chinese medicine. In Japan, it is the emblem of the prime minister.
In Japan, they associate the Empress tree with good fortune:
“They used to call paulownia ‘gold wood’ because you could pretty much sell the wood from one paulownia tree and buy a new car with the proceeds. When you gave birth to a daughter, you’d plant three paulownia trees, so that they’d be grown by the time she was ready to marry, and you could use them as dowry.” – Takeshi Suzuki.
Paulownia was once native to North America, but is not as well known here. Fossils of the leaves dating back to 40,000 years ago have been identified in Washington State.
“Rapid growth, high quality timber, prolific flowers, ability to coppice and regrow, along with being able to grow in depleted soils, and a natural resistance to insect and disease pressures, make Paulownia trees an extremely useful and valuable plant in the permaculture toolbox.”

A natural solution
Non-invasive,
nature approved
Is this tree invasive? Will it cause harm to ecosystems where it is planted? The short answer is: no.
There are between 9 and 23 species of Paulownia. One of these, the Paulownia tomentosa, is on the invasive species list. World Tree does not grow that variety. We grow Paulownia fortunei and Paulownia elongata, neither of which is invasive.
All Paulownia are prolific seed producers. However, the seeds are extremely hard to germinate – except under very rare conditions. That’s why we grow all our trees from tissue culture.
Paulownia does not have a detrimental impact on the environment. Quite the opposite. The tree’s natural ability to fix nitrogen and its nectar-rich flowers enhance rather than detract from the environment and Paulownia is becoming popular with the permaculture and ‘food farm’ community.
The Rainforest Alliance is internationally recognized as a certification program for sustainable forestry and best practices for tree planting and agroforestry. It has reported that the Paulownia tree as an ecologically sound tree for the purposes of reforestation and carbon sequestration.
Ecosystem services
Carbon sequestration
Leaves are the lungs of the tree, absorbing carbon from the air for photosynthesis. The enormous, heart-shaped leaves of a young Empress tree suck carbon from the air at a tremendous rate.
In a recent report, the Empress was found to be one of the most efficient trees on the planet for sequestering carbon from the atmosphere and returning it to the soil, making it a highly effective tool in reversing climate change. One acre of trees can absorb up to 54 tons of carbon per year at 10 years old.
Studies indicate that the Empress tree uses a unique and powerful type of photosynthesis. This system is found in only about 3% of all land plants, including some grasses like corn and sugarcane, but very few trees. This makes the tree highly efficient at sequestering carbon and storing large amounts of organic matter in its leaves.
Empress trees absorb 34 tons of carbon - or more - per acre
Regenerative
The seven generation tree
Perhaps the most impressive property of the Empress Splendor (Paulownia) tree is its ability to regenerate.
After harvest, the tree regenerates from the stump – without replanting. The strong, healthy root system produces vigorous new growth, which with proper pruning will quickly develop into a new tree.
This ability of the tree to replace itself without replanting makes it a truly sustainable, self-renewing source of timber for generations to come. The Empress will typically regenerate up to 7 times.
Ecosystem services
Companion planting
Empress trees intercrop well with many other plants, providing them with natural protection from the elements. In Latin America our farmers intercrop with coffee, cacao, plantains, corn and many other crops. The large leaves and rapid growth of the trees provides shade to the companion plants.
The deep root system of the Empress means they don’t compete with the other plants. It’s a perfect partnership.
Ecosystem services
Nitrogen fixation
The Empress tree also has special nitrogen-fixing properties that allow it naturally return nitrogen to depleted soil through its leaves and root systems. This process is most often found in legumes, and rarely in trees.
Nitrogen deficiency in soil is a result of industrial farming practices and a serious challenge to agriculture around the world. Farmers must spend millions of dollars a year on synthetic nitrogen fertilizers to ensure their crops’ survival.
Empress trees provide a natural solution to nitrogen deficiency. The leaves make excellent fertilizer estimated to contain over 3% nitrogen content.
Together with increased carbon in the soil, the nitrogen rich soil can retrain water more efficiently and provides a much more robust and resilient environment for all the plants and trees in the area.
Ecosystem services
Pollination service
The blossoms of the Empress tree are highly “nectariferous” creating a much-needed source of nectar for pollinating insects including honeybees. It is estimated that one acre of Empress tree blossoms can generate enough nectar to produce 100 jars of honey per year.
Without effective pollination services, one third of global agriculture would not be possible. The Empress therefore has a critical role to play in maintaining healthy agricultural systems, especially when planted with or close to other flowering crops such as coffee.

Other benefits
Animal feed
The leaves of the Empress tree contain over 20% protein and are excellent feed stock for ruminants.
Green fertilizer
Because the leaves of the Empress tree are high in protein, nitrogen, fats, sugars and phosphorus, they can form the basis of excellent green fertilizer. The nitrogen content in the leaves is comparable with the content of legume leaves. This makes there application an excellent way to enrich organic soil matter.
Bioremediation
Empress trees grow well in nutrient poor and even contaminated soils. The tree has been used successfully in mine reclamation projects shown to absorb heavy metals and nitrates. They can also be used as buffer around livestock operations and arable farms to prevent leaching.
