Can I plant flowers and shrubs in pots over winter, like heather? I am new to gardening, as hubby use to do all the gardening, and just had decking done in garden, so can only put pots out.

You can, but you need to treat your container garden as though you are gardening 1 zone lower than your current zone. So, for example, if you are in zone 5, you will need to treat your garden as though you live in zone 4. And should only expect plants that are suitable for zone 4 and higher to survive in the pots.
The reason for this is that without the insulation of the ground, the plant's roots are exposed to the elements more and experience weather as though it were colder than it is.
You can help ensure that your plants will survive the winter by placing them in a sheltered location when storing them for the winter. This can be against the foundation or wall of your house. Also covering the plants and pots with leaves or straw will further help to insulate them.
