The Eloise Butler Wildflower Yard workers in Minneapolis has place out a listing of only 5 bouquets that reliably bloom in April. Mainly because snow protect, temperature and other conditions differ, even these bouquets may look before or later than predicted. The 5 are: skunk cabbage, snow trillium, hepatica, bloodroot and false rue anemone. For some reason they did not involve the one we normally see initial at the Northland Arboretum in Brainerd, the pasque flower.
