How do I budge in the region of erudition the heading of a flower? I got a hanging picnic basket, I cant figure out what kind...

I got a hanging picnic basket, I cant figure out what kind of flower it is ( i get it at Home Depot, so they were no help), to me it looks like a mix between a pansy and a mauve. Its blue and purple with a little 'ring' type article inside the flower. Any ideas?
Thanks
Answers:    Cut off a piece and filch it to a nursery. They will be able to tell you the entitle. OR take a close up picture.
Go to k-mart or wal mart or boarders and find a book on annuals, thats what you get within hanging baskets, an you'll find out what you have. annuals are graceful to care for but you need to find out if they do better contained by sun or shade. Good luck Go to the library and look in a botanical book of flowers to identify it. They probably have pictures and identifications of most popular flowers out nearby.
