A couple years is how long poinsettias (Euphorbia pulcherrima) can grow.
Specifically, poinsettias are perennial shrubs in their native southwest Mexican and Central American homelands. Outside that native range, they tend to be grown as annuals whose life and death take place over the course of a year. But they have the potential to live much longer, if such critical conditions as appropriate levels of heat, light intensity and moisture are met.
