* Annual: This is the most common term and describes a plant that completes its entire life cycle (germination, growth, flowering, seed production, and death) within one growing season.
* Herbaceous annual: This term emphasizes that the plant has non-woody stems, which is typical for plants with green stems.
* Tender annual: This term specifically describes annuals that are not frost-tolerant and are usually grown as ornamentals in gardens.
* Summer annual: This term refers to annuals that germinate and grow during the warm summer months.
So, depending on the specific context, any of these terms could be used to describe a plant with green stems that lives only one season.
It's also important to note that some plants might have green stems but live for more than one season. For example, some perennials might have green stems that die back each winter and re-emerge in spring.
