200 seeds Blue Paulownia Princess Tree ,Worlds Fastest Growing Tree 200 seeds Blue Paulownia Princess Tree ,Worlds Fastest Growing Tree Deciduous tree native to Central and Western China. Hardy to -15 degrees F. Grows to 60 feet tall, with a spreading crown. The spacing of 20 feet apart is really pretty tight for a tree that can reach a fairly monstrous spread. This is the spacing for carbon sequesteration. For landscape use, single trees or trees planted further apart might be better. For coppicing, one cuts down the (5 year old or older) tree to the base. This can be done in the fall, after th tree has put on its growth. In the spring, the new sprouts will shoot up from the stump to a height of 15 to 30 feet. These new sprouts may be cut to use as poles, or may be left to form a multi-stemmed tree that is in turn allowed to mature for some time. This is one of the most signficant of all permaculture trees. It is used extensively in China as a divider between fields. Instant shade in the summer, with leaves as big as elephant ears and much greener. Spring flowers are large, luscious and so aromatic they can be detected from hundreds of feet away, wafting around on the wind. Sow seeds in early spring. Barely cover and tamp well. Keep evenly moist until germination, which occurs in about 6 weeks in cool soils. After the seedlings make their second set of true leaves, individuate and plant to pots, and work up in successively larger pots for a full year before transplanting. Young Paulownia trees will die down to the root during the winter of the first through third years.
