Bristleleaf bulrush is a delicate, grass-like sedge that thrives in consistently moist to wet soils, making it perfect for pond margins, bog gardens, or as a houseplant in a shallow water dish. It tolerates partial shade well and appreciates humidity, so indoor growers should mist regularly or place the pot in a tray of water. Minimal fertilization is needed — a dilute liquid feed once in spring is sufficient to keep it lush and healthy.
