Royal Paulownia Tree (Paulownia tomentosa). It is also known as Foxglove Tree because of the shape of the blossoms and Princess Tree because it was named for Anna Paulovna Romanov (1795-1865), daughter of Tsar Paul I and granddaughter of Catherine the Great.
You can take a ruler and measure the incredible difference in height every 2 or 3 days! It's like growing instant shade. Wait until you see the spectacular show when it starts to flower. Smothers itself in lavish masses of bouquets of breath-taking lavender-blue blooms. Huge leaves.
Grows in virtually any soil, requires no special care. Hardy To 30 Below. Soaring from a sapling to a roof high tree in just one year! Turns even the barest spot into a shaded showplace of beauty.
An old Asian custom was to plant a Princess Tree for good fortune when a daughter is born. Because it is extremely fast growing, it matures as she does. When she marries, the tree is harvested to provide furniture for the new home. The Paulownia is now widely used in making furniture and musical instruments.
