Theresa,
Are you planting the hanging basket with only petunias or are you putting other plants in as a combo?
I like the Ramblin' varieties, Opera Supreme, Shockwaves and Easywaves. My most fave yellow seed variety is an Italian petunia called Limenchello. T&M sell it.
There some new varieties this year, so I may have some new faves.
Have a look at this article for some tips.
