" Semi-evergreen" is a term used to describe plants that keep some of their leaves throughout the year, but shed others in response to seasonal changes. Despite its specificity, there are several synonyms that can be used to describe this characteristic. "Partially evergreen" is one option, as well as "seasonally deciduous" or "partly deciduous." Other terms might include "persistent foliage" or "semi-deciduous." Whatever the term used, it's important to recognize that this trait can be helpful in landscapes where year-round foliage is desired, but a complete evergreen presence isn't necessary.
