Michaelmas daisy is a frost hardy, bushy perennial which blooms from late summer to the end of October. It brings welcome color to the fall garden, and its ability to attract butterflies guarantees a steady supply of non-migratory butterflies to your Iowa garden (such as the Painted Lady Butterfly - Cynthia carduii). Performing best in boggy, moist conditions, Michaelmas daisy is low-mainteance and easy to grow. If you are seeking one of the hardiest fall bloomers, Michaelmas daisy will fit into your garden scheme perfectly.

Please note that the Zones listed above are USDA Hardiness Zones and are only given as a rough indication of whether a plant will grow and thrive in your area. Temperature variations and unusual weather conditions can affect plant survival. To assist plant survival during the winter, you may wish to place mulch over the areas in question or plant the flowers in an area away from walls or cement. Additionally, digging up bulbs and roots to overwinter indoors may be preferrable to keeping them in the ground.
