Rosebay Willowherb (Rosebay Willow Herb, Great Willowherb, Fireweed)

Feed in Moderation

Common Name: Rosebay Willowherb (Rosebay Willow Herb, Great Willowherb, Fireweed)
Latin Name: Chamaenerion angustifolium
Family Name: Onagraceae

Rosebay Willowherb belongs to a separate genus within the familiar Willowherb (Onagraceae) family. It is non-toxic, but is said to become less palatable as the leaves age. Like other members of this family, the Rosebay Willowherb contains relatively high levels of tannins, so we advise feeding in moderation only and suggest feeding younger, rather than older, leaves.

This common name 'Fireweed' should not be confused with the other plant called Fireweed (Senecio madagascariensis), which is from a different plant family and contains toxic levels of pyrrolizidine alkaloids.
