What plants are usually planted on university campuses?

Sophora japonica is a very common plant. Sophora japonica and pine are the two most common plants in university campus, because when Sophora japonica blooms in spring, the flowers are beautiful and fragrant, and then they can be easily preserved in university, which will create a glued atmosphere. Like pine trees, the campus is basically a little green in winter, which looks more comfortable, and both of them are cheaper and easier to raise.
