Aster novae-angliae.
New England Aster is a perennial wildflower native to most regions of the United States and Canada.
Plant grows to between 1 and 6 feet in height (though feel free to cut back the stems by mid-July if height becomes an issue) and produces bunches of fragrant, pink to purple blossoms toward the end of summer and into fall.
An important source of nectar for migrating Monarch butterflies, Aster is also the host plant for Pearl Crescent butterflies and Northern Pearl Crescent butterflies.
Direct sow just beneath the soil in late fall, watering once. For spring planting, mix the seeds with moist soil and refrigerate for 60 days (cold stratification). To start stratified seeds indoor, sow seeds in a flat, keep evenly moist, and provide a soil temperature of 65 to 70 degrees F. Germination should occur in 14-20 days.
Asters planted in the spring will typically bloom in the fall.

A Note on Cold Stratification
These seeds require cold, moist stratification. To naturally stratify the seeds, plant outdoors late fall on a weed-free site and allow seeds to overwinter.
To artificially stratify the seeds, place the seeds and a moist medium (such as a damp paper towel, coffee filter, sand, or vermiculite) in a labeled, sealed plastic bag and store in a refrigerator (33-40°F) for the amount of time noted on the growth chart before sowing.
