Answers:    Very few perennials concluding that long. What you need are annuals resembling petunias, begonias, marigolds, inpatients,etc. Did you ever consider some nice foliage plants like dusty miller, hosta, ferns, etc? Check out this pattern site.
good ol' marigolds and zinnias are frozen to beat
