Eupatorium album
Eupatorium album, the white thoroughwort, is a herbaceous perennial plant in the family Asteraceae native from the eastern and southern United States, from eastern Texas to Connecticut, inland as far as Indiana.[3][4] As with other members of the genus Eupatorium, Eupatorium album flowers with large numbers of small white heads. The flower heads have 4-5 disc florets each, but no ray florets.[5] The plant grows 50–100 cm (20–39 in) tall,[3] making it one of the shorter Eupatorium species.[5] Eupatorium album is capable of hybridizing with other Eupatorium species including Eupatorium sessilifolium and Eupatorium serotinum.[3] Its appearance is similar to Eupatorium altissimum, but differs in that the bracts (located at the base of the flower head) taper to a long point.[6] Eupatorium album grows in dry, open areas such as power lines, old fields, and eroded slopes. It will not grow under a shady canopy, but can be found in some open woods such as pine barrens.[6]
