GENUS INDEX

GENUS CODE: VERNO
GENUS SCIENTIFIC: Vernonia
GENUS AUTHORITY: Schreb.
GENUS COMMON: Ironweed
GENUS SUMMARY: A genus of about 20 species, perennial herbs, of e. and c. North America and n. Mexico; a few species in South America. Tradititionally very broadly circumscribed to include about 500 species, trees, shrubs, and herbs, of tropical, subtropical, and warm temperate regions, especially America and Africa; this broader circumscription appears increasingly indefensible.
GENUS IDENTIFICATION: Identification notes: Hybrids are frequent between co-occurring species. Only V. georgiana is keyed separately below (because of its distinctive appearance). Others may be recognized by intermediate morphology and ecological / geographic context.
GENUS REFERENCES: Strother in FNA (2006a); Jones (1982)=Z; Urbatsch (1972)=Y; Jones in Cronquist (1980)=SE. Key based on FNA and SE.

HORTICULTURAL
Plant Sale Text: Georgia ironweed is thought to be a naturally occurring hybrid between Vernonia angustifolia and Vernonia acaulis. It grows well in dry and sandy soils, and occurs naturally in the sandhills. Like other Vernonias, Georgia ironweed produces vivid purple flowers borne in loosely branched corymbs. These flowers are long lasting and attract many late-summer butterflies.
