About Marsh cudweed
Gnaphalium uliginosum, commonly known as marsh cudweed, is a small annual herbaceous plant belonging to the Asteraceae family, rarely exceeding 30 cm in height. It features branched stems and lanceolate leaves covered in fine whitish down, giving it a grayish appearance. It is ideal for wetland gardens or areas with consistently moist soils, where its modest presence can contribute to biodiversity.
Native range
Europe, Asia, and North America
Care tips
This plant thrives in full sun or partial shade, provided the soil remains moist. It requires constant and abundant watering, without allowing the substrate to dry out completely, as it is a species linked to aquatic or very humid environments. It prefers organically rich soils with good drainage that still retain moisture. The most common mistake is allowing the substrate to dry out, which will quickly lead to its decline.
