Ageratina ligustrina, the privet-leaved ageratina or 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 to pink composite flower-heads in autumn. [5] The fragrant flower-heads may be up to 20 centimeters in diameter and attract butterflies. [6] The leaves are light green, elliptic to lance shaped, with toothed margins. [7]
Ageratina ligustrina has been in cultivation since the mid 1800s, and in 1996, it gained the Royal Horticultural Society's Award of Garden Merit. [8] [9] It is not fully hardy in temperate regions. [5] In the US, it is suitable to be grown outdoors in hardiness zones 9–11. [7] A. ligustrina tends to be susceptible to slugs and aphids if grown outside, and whiteflies and red spider mites if grown in a greenhouse. [10]
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. [11]
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. [12]
Eupalin and eupatolin are flavonol rhamnosides isolated from E. ligustrinum. [13]
