Q.hydrangeas
I have a blue hydrangea that I have kept in the pot it came in. The first year it was beautiful and now it dies down in the winter and in the spring it becomes a beautiful green plant. I bring in during winter when it gets really cold here. I live on the Gulf Coast. I do it in shade outside in the summer. Should I plant it in the ground or perhaps put it in a larger container? Any advice will be appreciated.

This is really a personal choice. Yes, you can continue to grow the shrub in a pot. Just be sure the container is large enough to accommodate the plant and that it provides adequate drainage. It can also transplant fairly easy, but make sure it is done while dormant and get as much of the root system as possible.
