With an extraordinary growth rate and huge air filtering leaves that convert carbon into oxygen at a higher rate than almost any other tree, the Royal Empress Tree is rapidly becoming an important part of the solution to fight global warming.
They can consume and convert poor and polluted air at 3-4 times the rate of other trees.
Paulownias produce more oxygen than just about any other tree due to their extra large leaves and rapid growth rate. They are one of the most valuable trees for releasing oxygen back into the atmosphere.
Grows 10-15 feet a year
Can grow to a harvestable sized timber tree in 7-10 years.
Tree should be cut back to the ground in early spring of year two for even faster growth.
Paulownia trees can regenerate up to 7 times from 1 stump.
The leaves of the Paulownia are high in protein (21%) and nutrients, providing a good fodder for livestock.
Paulownia trees are excellent for intercropping (growing different crops together in same field). They are used widely in China by farmers who plant them in the fields and grow grain crops beneath them. The trees roots go very deep and do not compete with the crops for water and nutrients.
Grain crops planted beneath Paulownia trees have a higher yield because the trees improve the climate and reduce the damaging effects of strong winds.
When the leaves drop they decompose quickly and release valuable nutrients back into the soil.
After 8-10 years the trees can be cut for timber and become an added income for the farmers. They will regenerate again from the cut stumps, saving the cost of replanting the fields.
In China, paulownia trees are being used successfully in agroforestry projects and for intercropping with agricultural crops on close to 5 million acres of farmland.
The flowers of the Paulownia tree produce a very uniquely flavored honey that is especially popular in the Orient.
With their ability to grow to a mature timber sized tree in 7-10 years, Paulownia trees are becoming highly valued for their use in the lumber industry. The wood is strong and light. It is a high quality lumber with a very beautiful wood grain. It has been highly prized in Japan for many years. It is estimated that in the last 5 years, 1.2 billion Empress trees have been planted in Japan for forestry and lumber production. The wood is 30% stronger than Pine and 40% lighter than all other hardwoods.
Plantations of Paulownia trees are springing up around the world, as people are realizing the benefits of planting acres of these trees instead of the far slower growing pine tree. It is estimated that for each acre of Paulownia trees planted an average yield of 30,000 board feet of lumber can be expected every 7-10 years. With an average price of $3.00 per board foot, the estimated return on 1 acre of Paulownia trees is $90,000 every 7-10 years.
The trees will then regenerate themselves from the same stumps, saving the cost of replanting.
The rapid growth, beautiful fragrant flowers, and large green leaves add aesthetic value to any place they are planted
