Bilbao’s Fleabane (Erigeron acer) is a flowering perennial plant that is not native to the UK but has become naturalised in some regions. Belonging to the Asteraceae family, it is characterised by its daisy-like flowers with white or pink petals and yellow centres.

Bilbao’s Fleabane thrives in various habitats, including grasslands, meadows, roadsides, and waste ground. It prefers well-drained soils and can tolerate both full sun and partial shade.

As a non-native species in the UK, Bilbao’s Fleabane may not have evolved specific predators. However, it may face competition from native plants for resources.

The lifespan of Bilbao’s Fleabane can vary, but it typically behaves as a short-lived perennial, regrowing from its base each year.

Culturally, Bilbao’s Fleabane doesn’t hold significant historical or medicinal importance in the UK. However, it is appreciated for its ornamental value in gardens and naturalistic landscapes.

Interestingly, the name “Fleabane” originates from the plant’s historical use as a natural insect repellent, particularly against fleas. While not as effective as modern insecticides, the dried leaves were once used to deter fleas from bedding and clothing. Despite its name, Bilbao’s Fleabane is not considered a significant control method for fleas today.
