Paulownia elongata is a species of plant in the Paulowniaceae family. It is used as a forestry tree in North America and China. It is reportedly the fastest growing hardwood tree, which are known to grow up to 15 or more feet in the first year. Commercial plantations are normally established from selected clones resulting from micropropagation. Some proponents claim that P. elongata plantations can reach a harvestable size in five to seven years. Leaves are very large and pubescent. This species can withstand a very wide range of environmental conditions, however, it will not grow at altitude.
Paulownia elongata has a number of uses:
a) An ornamental tree of parks and gardens; grown for its purple flowers and shade tolerance.
b) It is a forestry tree producing strong, yet light wood.
c) Owing to the large quantity of biomass produced annually, it is suited for use as a feedstock for biofuel production.
Paulownia trees may be grown in colder climates, but the tree will die back to the ground every winter. If it dies back every winter it will never reach mature blooming size, but it will still add interesting foliage to your yard or garden for the summer. Mulch roots heavily with straw or leaves in fall in climates that get below 15 degrees F (10 degrees C).

|Germination||Paulownia seeds are easy to germinate! Germination rate will be between 60 and 90%. The average is 80%! <br /> Sow seeds on the surface of the prepared moist soil, cover with clear plastic for humidity control and place in very light (no direct sunshine) and warm (~+25C) place. <br /> Germination is quite fast!<br /> For more detailed info on propagation: <br /> http://oldwww.planetc.com/early-bird/stockpit.htm <br /> http://www.ca.uky.edu/agc/pubs/for/for39/for39.htm|
