![]() ![]() They are thick, firm, with entire or toothed margins, are variously hairy on both surfaces and typically wither by flowering. Leaves are present mostly towards the lower stem. Away from the flower the stems vary from being nearly smooth (glabrate) to covered with stiff, short hairs (hispidulous), while within the arrays the stems bear either minute, long, soft straight hairs (pilosulous) or straight stiff, sharp appressed hairs (strigillose). The plants are short-rhizomatous or have branched, woody stems and roots. Symphyotrichum oolentangiense is a native perennial that grows in erect, dense clumps ( of 1 to 5+ stems reaching up to 1.5 m tall. They are 1.8-2 mm long and 4-5-nerved, and smooth (glabrate) to sparsely covered with short stiff hairs and tipped with cream or slightly rose-tinged hair tufts (pappi) 3-4 mm long (Brouillet et al 2006). The fruits are dull purple or stramineous with purple streaks, oblong-egg-shaped (obovoid) and more or less compressed. The individual involcral bracts (phyllaries) are in (3-)4-6 series, lying flat (appressed) or slightly spreading with a distinct dark diamond-shaped tip. The whorls of bracts (involucres) enclosing the flower base are bell-shaped to elliptic bell-shaped and 4.5 to 8 mm long. The heads are 19 to 34 mm across and have 10 to 25 usually pale to azure blue to violet-purple (rarely rosy, white or bluish white), ray petals. The flowering heads of Sky-blue Aster are borne in open, loose, narrowly-branched, stiffly upright, more or less pyramidal clusters. As with all asters, the infloresences are arranged radially into "heads" of many separate ray and disc flowers, with each head superficially resembling a single flower. The upper leaves are lance-like and stalkless but do not clasp the stem. The lower leaves are distinctive with long, often winged stalks with expanded, heart-shaped bases and scabrous upper surfaces. Leaves are mostly concentrated towards the lower stem and are thick and firm, with entire or toothed margins, are variously hairy on both surfaces, and typically wither by flowering. Away from the flower arrays the stems vary from being nearly smooth (glabrate) to covered with stiff, short hairs (hispidulous), within the arrays the stems bear either minute, long, soft straight hairs (pilosulous) or straight stiff, sharp appressed hairs (strigillose). ![]() Symphyotrichum oolentangiense is a native perennial that grows in erect, dense clumps of 1 to 5 or more stems reaching up to 1.5 m tall.

Canopy codominants include five or more of the following species: red oak, red maple, white ash, American beech, sugar maple, black cherry, cucumber tree, and black birch. A canopy with a relatively large number of codominant trees characterizes this forest. It occurs on rich, fine-textured, well-drained soils that are favorable for the dominance of a wide variety of tree species.
