Find a good garden centre and visit it regularly throughout the year, what you will find is that at any specific time of year they will be promoting those plants which provide colour and look their best. Therefore rather than doing one visit and buying lots of stuff, visit every month or so and buy smaller amounts. That way you will end up with colour/interest all year round.
The other bonus of doing things slowly is that you can correctly space stuff. An easy pitfall to fall into is to cram too much stuff in too close together. Which when it grows it becomes too crowded. It's easy to do this as we naturally want things not to look too sparse, but sparse is good when starting out.
