About Fleabane
Erigeron bonariensis, also known as Argentine Fleabane or Buenos Aires Fleabane, is an annual or biennial herbaceous plant belonging to the Asteraceae family, native to South America but widely naturalized in temperate and subtropical regions. It is characterized by its branched stems that can reach up to 1 meter in height, covered with lance-shaped leaves and small whitish or slightly pinkish flowers grouped in capitula. It is ideal for low-maintenance gardens, rockeries, or for naturalizing areas, providing a wild and ethereal touch.

Care tips
This species is remarkably hardy and undemanding. It thrives in full sun to partial shade and tolerates a wide range of soils, though it prefers well-drained ones. Watering should be moderate, allowing the substrate to dry out between waterings, as it is sensitive to waterlogging. A common mistake is overwatering, which can lead to root rot; it's better to underwater than to overwater.
