Cultivars of Sophora japonica:
MillstoneTM (‘Halka’) has a good symmetrical form and is less susceptible to stem canker. Regent® is resistant to leaf-hopper.
`Pendula' (weeping pagodatree) has pendulous branches.
Japanese pagodatree tolerates urban conditions and is suited for large areas where it can spread. Form and branch structure can be variable, thus purchasing a cultivar with a desirable form is suggested. The shade provided by this tree is not dense, but creates a nice filtered light.
The common name comes from the fact that it was planted around Buddhist temples in Asia.
