(Paulownia tomentosa) It is a very fast growing dense shade tree for the Pacific Northwest and other areas with mild winters. It is hardy in USDA Zones 7-10. The wood is extremely valuable and has many uses. In colder parts of its range, for the first few years, the new growth dies back each winter but tremendous summer growth more than compensates. In Japan, the wood is traditionally used to make dowry chests and other furniture. Each spring, the tree is covered with clusters of trumpet shaped two inch long fragrant flowers that are lilac blue; a display of spectacular beauty. They provide good bee forage in the spring. Young trees grow best if given a lot of water in summer. Even young trees have two foot diameter heart shaped leaves.
