Cyperus Polystachyos Chimney Sweeper

Description

Cyperus polystachyos 'Chimney Sweeper', commonly known as Chimney Sweeper Sedge, is a striking ornamental sedge characterized by its upright, grassy foliage and unique inflorescences that resemble miniature chimneys or sweeping brushes. Its many-spiked flower heads, ranging from dark brown to black, create a bold, architectural element in water gardens, borders, or naturalized areas. This versatile plant thrives in moist to wet soils and tolerates periodic flooding, making it ideal for rain gardens, pondsides, or low-lying garden areas. Chimney Sweeper prefers full sun to partial shade, and its ability to withstand various soil conditions ensures reliable growth in challenging environments. Drought-tolerant once established, it requires minimal maintenance and supports wildlife by providing habitat and food sources for pollinators and aquatic insects.

Sowing Advice

Sow seeds in spring or autumn. Use a wet, well-draining seed-starting mix and scatter seeds thinly on the surface without covering, as light aids germination. Maintain consistent moisture, keeping the seed tray in a bright location with indirect light. Germination typically occurs within 2–4 weeks. Once seedlings have established, transplant them into individual pots and grow them on until they are robust enough for outdoor planting. Space plants 20–30 cm apart in wet or consistently moist soil.
