Q.lantana plants
I notice some info at nursery reads “lantana” is annual. Another lantana is labeled perrenial. Which is it? I have had lantana that beautifully returns every year, so I thought it would be so hardy, and planted extensively at another house with even more sheltered area and not ONE returned. Are some varieties annual and others perrenial? I am stumped. 🙁

Most plants that we call “annuals” are actually tender perennials that can't survive winters in colder climates.
