planting iris bulbs in springtime

today I bought 3 bearded iris already beginning to grow in their pots, do I plant them now April 28, 2009 in Green Bay, WI area or should I be concerned about possible frost? Everything I read says to plant in late summer.

Doug says plant now. First of all, Bearded Iris aren't bulbous iris. So spring planting is fine and they should shrug off frost
