Ageratina riparia
Also called Creeping Croftonweed, Mist Flower, Mistflower, River Eupatorium, Mistflower Or Creeping Croftonweed
Mistflower is a sprawling, low-growing perennial herb in the daisy family, native to western Mexico and grown as an ornamental. It is highly invasive in tropical and warm temperate climates, so grow it with care and avoid planting it outdoors where it can spread.
Ageratina riparia, commonly known as mistflower, is a species of flowering plant in the family Asteraceae, native to Mexico. The species is widely adventive and has spread to Cuba, Jamaica, and other parts of the Caribbean. It has also been introduced as an ornamental plant and naturalized in a variety of regions, including parts of Hawaii, South Africa, Southeast Asia, Macaronesia, Oceania, Peru, and the Indian subcontinent. In tropical climates, A. riparia is highly invasive and a variety of control methods have been developed to reduce its spread.
Mistflower is native to western Mexico. In its natural habitat the flower occurs sparsely and may even be considered endangered. Specimens were originally collected from the canyon of El Mirador, Mexico in 1857 for use as an ornamental plant. It was then brought back to Germany by Jean Jules Linden. From Linden's specimen, mistflower was introduced to many parts of the globe as an ornamental plant during the late 19th and early 20th centuries.
Mistflower has most commonly been used as an ornamental plant. It may also be harvested for use as a tanning agent. In some regions, it is used for the stabilization of embankments and for partitioning land.
