| Perennial means living for more than one year, needing more than one season to reach maturity and flower, set seed. As far as I know all orchids are perennial. Yes those of us in temperate regions usually think of the herbaciouse perennials in the yard, they die back in winter and come back in spring, hopefully for many, many years. But technically speaking tropical plants that have long life cycles are also perennials. In that case the term is often ammended to tender or tropical perennial so hopefully people will not expect to leave them out through snow and have them come back. |
