There are not too many flowers that I don't like although I do tend to prefer those that stand tall and strong. Some I like for their foliage, some for their flowers and others for their uniqueness.
Then there are Marigolds. Yuck! They have no redeeming qualities. They smell gross. Even bugs hate them apparently. That's why I have them in my veggie bed. Rumor has it that they are supposed to keep the bugs at bay but someone forgot to tell the bugs in my neck of the woods because they have been decimated. Just straggly little skeletons at the feet of the tomatoes, etc. Not a success in my experiments.
