Where to get info nad buy about flower

I want to make the flower bed describe on this site:
http://www.hgtv.com/hgtv/pac_ctnt_nobanner/text/0,1783,HGTV_10680_30294,FF.html #
Where can I read about and order the needed flower? My guess is that I cannot find all I need locally.
Any other site has a detail plan like the one above?
