Welcome to the Scottish Invasives blog. Invasive non-native species (or INNS) are plants and animals that have been introduced to areas outside their natural range. INNS are currently recognised as one of the greatest threats to biodiversity. The Scottish Invasives blog is intended as an informal forum for those interested in invasive species control.

Reaching for the sky

Giant hogweed. Everything about this plant is big, even its name ... Heracleum mantegazzianum.

It is a biennial, so individual plants die after flowering. However, its seeds can survive up to 5 years in the soil, so whatever treatment is used, control must be continued for at least 5 years on any given site.
