Hello Lindylou,
Have a look at our pots and containers section to see what you like the look of:
http://www.gardenersworld.com/plants/pots-containers/
Personally I love the look of trailing plants in an urn. This is easy in summer as you can use bedding like petunias, bidens, verbenas and my favourite Dichondra 'Silver Falls'.
In the winter it's a bit harder, but variegated ivy trails beautifully, and Muehlenbeckia complexa will do the job but would be best in a sheltered spot.
For a strongly architectural look try our hosta display:

Add a copper strip around the pot to deter slugs.
Enjoy it, it's always fun to have a new project you can start from scratch.
