Ageratina altissima 'Chocolate' (Asteraceae)
1998 Native Plant of the Year, Millersville Native Plant Conference. 'Chocolate' is an exciting selection of a great native, an introduction from the Mt. Cuba Center for the Study of Piedmont Flora. Chocolate-tinted foliage on purple stems stands out in the garden and is much more refined and showy than the foliage of the straight species. 6" clusters of creamy white flowers bloom in late summer and early fall. Average-to-moist soil and full-to-partial sun all suit 'Chocolate' just fine. (Formerly Eupatorium rugosum.)
