First of all, WELCOME!
You'll love it here.
Okay, a set that doesn't have a flower in it that you will get a lot of use from... hmm.... Well, you could always get a greetings set (one that is just words), like one of the All Year Cheer ones (they are kinda pricey though). Most of the reasonably priced sets that I use a lot have flowers (of some sort) in them! Hmm, tougher than I thought. Ladies, any suggestions???!!!
Oh, and I agree w/ Cathy, Mini Mates would be a good set for a nice variety of images.
