This is one of the very best late wildflowers for butterflies. It is the only Eupatorium native to Britain.In this photo there is a rare White-letter Hairstreak feeding on it.
the flowers also attract many moths at night.
This plant likes to grow in damp conditions, where it can grow to 3 or 4 feet tall (if kept drier it will flower on a shorter stem). A hardy herbaceous perennial.
