Ageratina riparia


Mistflower is a low growing, sprawling perennial herb that grows up to 40x60 cm high. Its stems produce roots at joints that touch the ground. The serrated leaves on average reach 7.5 cm long and 2.5 cm wide and taper at each end. The flowers are white with dense heads at the ends of the branches. Mistflower buds from July until August, with full flowering occurring from August through October. Seeds are black, slender, angular, 2 mm long, with fine white hairs at the tip. They are dispersed by wind and flowing water.


Misty, upland meadows and mountainous areas with high rainfall. Can invade a variety of natural forest habitats, especially along riverbanks, as well as disturbed areas such as roadsides, pastures and plantations. It is shade tolerant but frost sensitive.


Mistflower is maybe poisonous for mammals to eat.
