Cute puppy Tia, and welcome to the iris forum!
I can't say I have a truly disliked flower...but there are some I avoid for certain reasons like the little spent flower on forget-me-nots that stick to everything, even though I like them for many reasons I choose to not grow them anymore, at least for now. Another that I just haven't found one I'm really happy with is African daisies. I have bought them, but never been impressed with the result. But I would not rule out the possibility of buying one again if I really liked the color, to give it another try in a different location. I have some daylilies which are struggling due to the hot summers and the sandy soil. It's hard to keep them wet enough.
But then I'm such a sucker for plants...I like just about anything that grows!
