Ageratina ligustrina (privet-leaved ageratina, privet-leaved snakeroot), is Mesoamerican species of evergreen flowering shrub in the sunflower family. It is widespread across much of Mexico and Central America from Tamaulipas to Costa Rica.[2][3][4]
Ageratina ligustrina grows to 4 metres tall, producing flat heads of daisy-like white composite flower-heads in autumn. It is not fully hardy in temperate regions.[5] In cultivation it has gained the Royal Horticultural Society's Award of Garden Merit.[6]
Etymology
Ageratina is derived from Greek meaning 'un-aging', in reference to the flowers keeping their color for a long time. This name was used by Dioscorides for a number of different plants.[7]
The Latin specific epithet ligustrina highlights the plant's resemblance to the privet Ligustrum, though the two plants are not believed to be closely related.[8]
Chemical Compounds
Eupalin and eupatolin are flavonol rhamnosides isolated from E. ligustrinum.[9]
