Quick facts

About Branched bur-reed

Sparganium erectum, commonly known as branched bur-reed, is a robust perennial aquatic plant characterized by its tall stems and spherical, spiny flower heads. It's ideal for pond margins, wetlands, or water gardens, where its architectural forms can be appreciated. It adds interesting texture and valuable habitat for wildlife.

Native range

Much of Europe, North Africa, and temperate Asia.

Care tips

This species prefers full sun to partial shade and thrives in permanently wet soil or submerged in shallow water (up to 30 cm deep). Consistent watering is crucial, as it does not tolerate drought; ensure its roots are always in contact with water. A substrate rich in organic matter is beneficial, but it adapts to most aquatic soils. A common mistake is planting it in dry soil or a container without water drainage, which will severely limit its growth.
