About Guernsey fleabane
Erigeron sumatrensis, also known as Sumatra Fleabane, is an annual or biennial herbaceous plant belonging to the Asteraceae family, native to South America but widely naturalized. It is characterized by its erect, branched stems, which can reach up to 1.5 meters in height, and its small white or slightly pink flowers clustered in heads. It is ideal for naturalistic gardens, roadside edges, or as a pioneer plant in disturbed areas.
Native range
Tropical and subtropical South America
Care tips
This species is highly adaptable and low-maintenance. It prefers full sun to partial shade and tolerates a wide range of soils, even poor or dry ones, as long as they are well-drained. Watering should be moderate, allowing the substrate to dry out between waterings, as it is quite drought-tolerant. Avoid overwatering and waterlogged soils, which can lead to root rot.
