Hi Everyone! My daughter gave me a beautiful hibiscus for mothers day. My only concern is whether it is a tropical or a perennial? Any advice would be helpful. I have tried reading about both and can't quite differentiate. The tag on the plant said full sun, hardy to 20 degrees farenheit, fast grower and to keep moist. Don't want to take a chance on putting it in the ground and losing it...would rather keep it in a large pot on the deck if need be. Any advice would be much appreciated. The flowers are a blended pink with a deeper pink center.
