Paulownia, native to China, is a fast-growing, deciduous tree that reaches heights of 30 to 60 feet. If you are looking for a fast-growing, attractive shade tree, consider the paulownia (also called the princess tree) as it can grow up to 10 feet tall in its first year. Paulownia is considered invasive in certain parts of the southeastern United States, so check with local agencies prior to planting it. Paulownia suffers from weak, brittle wood. Consequently, these trees live to a maximum of 70 years.
Mix together equal parts of sand, peat moss and vermiculite. Moisten the mixture well and pour it into the pot, to within 1/2 inch of the rim.
Place the paulownia seed on the surface of the soil and cover it with 1/8 inch of moist sand. Place the potted seed in a bright area, out of direct sun. Do not allow the soil to dry out; keep it moist but not soggy. The seed should germinate within one to two weeks.
Keep the paulownia seedling indoors over the first winter and transplant it into the garden the following spring, after the danger of frost has passed.
