Japanese Pagoda Tree Choices
Sophora japonica 'Regent' - the cultivar of choice, selected for its even more rapid growth rate, relatively straight central leader, earliness to flower (at about 5 years old), and glossy dark green foliage. S. davidii is a medium- to large-sized, deciduous shrub that has grayish-downy branches, which will eventually be equipped with spines. The leaves consist of 7 to 10 leaflets and in early summer clusters of small, bluish-white flowers are borne. S. tetraptera, known as the New Zealand Sophora and Kowhai, is an evergreen large shrub or small tree that can reach a height of 20 feet. This tree is only hardy in mild climates. The branches of the Kowhai are spreading and drooping and are clothed with a yellowish down when young. In late spring, pendant clusters of tubular, bright yellow, 2-inch flowers are produced; these are followed by seedpods that look like rows of beads. Its leaves consist of 10 to 20 leaflets. Princeton Upright TM has a compact, upright branching habit that makes the tree a suitable choice as a street tree.
