Flowers for 2012

Please can anyone recommend a type of flower

I wish to display the date 2012 in flowers but they need to be a dwarf
variety and in bloom July-August

I have a space 6ft x 5ft to plant up

Many thanks in advance

Marigolds, surrounded with white lobelia or alyssum

Hows about Ageratum Heres a link to show what they look like, not particularly to buy from:

I believe it comes in Blue, mauve, pink, white.

Or those little begonias example here, although they may be more green than flowers:
