Royal Empress Trees were named after Anna Paulownia, daughter of the Czar of Russia. In springtime, the Royal Empress Trees blossom in full regal splendor; sprouting masses of lavender flowers… shaped in large pyramid-bell clusters that produce a rich fragrance. The Empress Tree is the world’s fastest growing shade tree. In fact the tree grows so fast, it turns a bare lot into a royal estate… making it the envy of professional landscapers. Believe it or not, the trees grow in almost any kind of soil without any special care… seldom troubled by pests.. they even withstand pollution problems from urban areas. It is a hardy tree that resists temperature from -10 F to 110 F. Simply add water… Stand Back… and Watch it Zoom!!! My backyard is absolutely breathtaking in the spring and smells oh so yummy. I’ll be sure to post pictures in the Spring.Royal Empress Trees are also known as the Royal Paulownia Tree.
