Invasive Plant
Common Foxglove
Digitalis purpurea
 

Unfortunately this very striking old fashioned plant has become an environmental weed. Although it is an herbaceous perennial, it was commonly grown and sold as an annual. Clusters of pink, purple or white hanging bell-shaped flowers are borne on tall upright flower stems. The leaves form a dense rosette of hairy basal leaves. It invades wet forests, riparian and alpine areas where it replaces native herbs.

 

HOW IT SPREADS

  • It produces prolific amounts of seeds which readily germinate within the garden and adjoining disturbed bushland.
 

Please note: This species is extremely toxic to humans and livestock.
