King & H.E. Robins. var. altissima Habitat: Mesic to dry-mesic upland forests, especially cove forests and rich montane oak-hickory forests; less numerous but widespread in dry forests and woodlands (especially over calcareous or mafic rocks), well-drained alluvial forests, clearings, and more open, disturbed habitats. Common in the mountains; frequent in the Piedmont; infrequent in the inner Coastal Plain; rare in the outer Coastal Plain.

King & H.E. Robins. var. roanensis (Small) Clewell & Wooten Habitat: High-elevation forests, especially cove forests and northern hardwood forests; also on balds. Locally common in the sw. mountains. Unequivocal Ageratina altissima var. roanensis is known only from higher elevations of the Southern Blue Ridge, especially the Balsam Mountains in Grayson, Smyth, and Washington counties, where it is common. However, it has been attributed by various sources to counties in the Ridge and Valley and the Northern Blue Ridge, ranging to nw. Virginia. Some of these reports may be referable to large plants of var. altissima that approach var. roanensis in certain characters (see comments), but whether this taxon occurs outside the Southern Blue Ridge needs further investigation.
