on perennial vs annual
The status of a plant , has to do with its natural life cycle , not necessarily if it survives a specific winter zone.
but it can become confusing and to a lot of people it is an annual if it dies over winter and has to be replanted again in the spring.
When I lived in Michigan we called roses annuals , because most had to be replanted yearly
and to a lot of people it is an annual if it dies over winter and has to be replanted again in the spring.
