Seed Biology and Germination:
Population Dynamics and Dispersal:
Spread by seed.
Origin and History:
South west and central Europe.
ACT, NSW, TAS, VIC, WA.
Ornamental. Medicinal. Source of a heart stimulant, digitalis.
Weed of burned areas, disturbed areas, roadside, fence lines, coastal areas and poor pastures.
Invasive weed of the USA.
All parts of the plant are toxic, especially the seeds.
Rarely eaten by stock.
Toxic to cattle, wildlife and humans.
Each year people die from drinking tea made from Foxglove leaves when they mistake it for Comfrey.
Management and Control:
Avoid burning. Improve pasture by planting well adapted species and applying adequate fertiliser. Foxgloves may be common in newly developed pastures but usually disappear as the pasture establishes.
Young plants can be manually removed. This needs to be repeated for several years. Herbicides are often only partially effective because they can't penetrate the furry leaves. Try adding Pulse Penetrant if treating with herbicides.
Relatively tolerant to glyphosate and other herbicides.
Ornamentals such as Veronica, Antirrhinum (Snapdragons), Calceolaria, Nemesia, Penstemon, Mimulus, Bartsia, Bellardia and Parentucellia.
