Question: what is zone 5 9 in gardening?
Answer: If your zone is equal to or higher than the zone listed for the plant it will be hardy for you, it is perennial in your area. An example, I live in zone 5. If the plant tag says a plant is hardy in zones 5 to 9 the plant will be perennial for me. It would also be perennial in zone 6, 7, 8, and 9.
