What does Fleabane look like?
Fleabane plants are usually well-branched, with upright stems and a bushy appearance. Their flower heads look like small daisies, with many narrow ray petals in shades of white, lavender, or pink, surrounding a yellow disc in the center. Some species lack ray flowers altogether. The pappus, or crown of bristles on the fruit, is shorter than in true asters. Leaves and overall size vary widely across the genus.
Where does Fleabane come from?
The genus Erigeron is found worldwide, with its greatest diversity in North America. The name 'fleabane' comes from an old belief that dried plants could repel fleas, though this is debated. The scientific name comes from Greek words meaning 'early in the morning' and 'old man', referring to the white hairs on the fruit after flowering. The genus is closely related to asters and true daisies.
When and how Fleabane blooms
Fleabane species can be annual, biennial, or perennial. They grow from seed and thrive in a range of soils and climates, depending on the species. Many are cultivated as ornamentals, with garden varieties selected for their flower color and form. Named cultivars include 'Wayne Roderick' and 'Dunkelste aller', which has deep-violet, semi-double blooms.
How Fleabane is used
Fleabane is often grown in gardens for its daisy-like flowers and is valued as an ornamental plant. In the wild, it provides food for the larvae of certain moths and butterflies. The belief that it repels fleas is part of its folk history, but not a common use today.
Kinds of Fleabane
There are around 460 species of Erigeron, with notable ones including blue fleabane (Erigeron acer) and long-leaf fleabane (Erigeron corymbosus). Cultivated forms vary in flower color and petal shape, with some selected for especially vivid or double blooms.
What Fleabane means
The name fleabane reflects a traditional belief in its ability to repel pests, though this is now considered a misnomer for North American species. The genus is not strongly tied to symbolism or ceremony, but its daisy-like flowers are a familiar sight in gardens and wild meadows.
