Eupatorium are hardy perennials. They can reach heights of between 60 cm and 3 m (2 to 10 feet), making them ideal for use in borders.
They bloom from Summer to Autumn, when they display clustered flowers of white, purple, or pink, atop heavy foilage.
Some of the more common names for Eupatorium plants include Mist Flower, Throughwort, Boneset, Hardy Ageratum, and White snakeroot.

Mist flower and other Eupatorium plants like to grow in a sunny or partially shaded part of the garden. They like a soil that is moist and acidic (pH 5 to 6).
If you plan to first grow Mist flowers indoors, then they should be prepared about ten weeks before they are due to be put in the garden (either after the last frost of spring or in the autumn).
They take from between one to three months to germinate at a temperature of about 13 degrees centigrade (55°F).
Once ready for transplanting, the Eupatorium should be spaced at about 40 cm / 16 inches apart (smaller species) or 75 cm to 1.25 metres / 2 1/2 to 4 1/2 feet) apart (larger species).
If you require more Mist Flower plants, then they can be propagated by division in the autumn.
Eupatorium plants should be cut back to the ground at the end of the flowering season in the Autumn. Divide every three years to keep them looking fresh.
