In the garden
Eupatorium ageratoides sits in the genus Eupatorium within the daisy family (Asteraceae) and is sold under the common name White Snakeroot. Its flowering period runs from July to October, providing white heads through late summer and into autumn. Specific cultural requirements can vary between suppliers and taxa, so consult the plant label or nursery notes for precise advice on light, soil and hardiness for the stock you buy. As a general planning note, place specimens where their mid-to-late-summer blooms will be seen from paths or among other perennials that benefit from white accents late in the season. Remove spent flowering stems to tidy the planting after bloom if a neater look is required. Because the name white snakeroot also applies to Ageratina altissima, a species known to be poisonous, take care with identification and with siting near grazing animals or play areas. Expect the white flowering display to continue through July to October, making it useful for extending neutral-colour interest into the later months of the growing year.
