Habitat: Aster cordifolius is native to central and eastern North America – Nova Scotia and New Brunswick to Ontario, Minnesota, Georgia and Missouri. It grows primarily in mesic sites with soils that are rocky to loamy but generally rich, at heights ranging from sea level along the coastal plain up to 1,200 m (3,900 ft) in the Appalachian Mountains. It can be found on open wooded slopes, along the banks of streams, on moist ledges, in swampy woods, along the borders of beech–maple forests and oak–hickory forests, as well as in clearings, thickets, and along roadsides and ditches. It also can be found in urban areas where it is sometimes considered a weed species.

Aster cordifolius is a Perennial plant, growing to 1.5 m (5ft) by 1 m (3ft 3in). The lower leaves are heart-shaped, while leaves higher on the stem tend to be sessile with more rounded bases. It is in flower from September to October. The composite flowers, which have bluish to rarely white ray florets and light yellow disc florets that eventually turn purple, emerge in August and persist into October. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees, flies, beetles, Lepidoptera (Moths & Butterflies). The plant is self-fertile.

Through Seed – surface sow in spring in a cold frame. Do not allow the compost to become dry. Pre-chilling the seed for two weeks can improve germination rates[134].

Basal cuttings in late spring. Harvest the shoots when they are about 10 – 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
