Gardeners' Notes:

Positive plant_it On Jun 26, 2013, plant_it from Valparaiso, IN wrote:

Native to North America (from Nova Scotia to Minnesota south to Illinois, Ohio and North Carolina). This lovely plant flowers July-Oct and gets from 1-4 feet. Violet to pale blue flowers with yellow centers. Prefers part shade & shade. Likes moist, well-drained, sandy loams.

Asters are an important food source for butterflies and are essential to the survival of over wintering colonies of honeybees and other social insects. The seeds that are produced after flowering become food for migrating and resident songbirds.

Looks well when massed. Use it to naturalize an area. Large Leaf Aster can spread through it's roots as well as by seed. Makes a good substitute for Hostas. Fall flowering can sometimes be sparse, so I plant it for it's foilage effect -- the large basal leaves get 4-8 wide. Unlike Fall mums which frequently do not survive our harsh winters, your asters will return year after year.

Spreads too much and not ornamental enough to be of use in the home landscape. Very root-persistant. If you just want a native groundcover, wild ginger is much better. It spreads slower the and over-all look is better.

Large Leaf, from the heart shaped basal leaves, up to 6" x 8" in size. Other common names include Bigleaf Aster, Lumberjack Toilet Paper.
