Royal Paulownia, Empress Tree, Princess Tree
Rounded, dense crown, resembles Catalpa bignonioides
Warm, mid-south, east coast moist to warm soils. Extremely weedy
Paulownia can be a weedy and messy tree that requires a fair amount of clean-up in the fall. Flowering isn't gauranteed in colder northern climates. Best used in areas with plenty of space, similar to the needs of a Catalpa. This plant is invasive.
Usually opposite but sometimes whorled, simple, broad-ovate, large pubescent leaves.
Buds are obvious all winter, very pubescent.
Olive brown color and heavily lenticelled.
Panicle, formed in summer; individual flower buds appear as light brown, pubescent spheres through winter.
Light brown aging to dirty brown. Non-ornamental.
The seeds exhibit no dormancy, but light is necessary for germination. Root cuttings are less successful.
'Coreana' - Yellow-tinted leaves, woolly beneath, and violet-speckled, yellow-throated flowers.
'Lilacina' - Pale lilac flowers.
