Jean: Beautiful Hibiscus! You did a wonderful job of the raised beds and how lucky that the neighbor got a new washer so you could have the box ... the heavy cardboard as a weed block works much better than the black plastic weed barrier in my opinion. I used to have that same
Ti Plant (Cordyline fruticosa) and it bloomed every year but I think it's one that froze during one of our exceptionally cold winters or else it was one of the plants I gave to neighbors when we moved.
