Cultivation details

Identification & Habit: Triangular-stemmed perennial with thick rhizomes and terminal brown inflorescences. Dense colonies in lakes and riverbanks. Growing in moist and wet terrestrial habitat, and in shallow water. The root system is well-developed. Prefers waterlogged soils in full sun or part shade. Schoenoplectus californicus (California bulrush): Large emergent bulrush with compact spikelets of tiny flowers. It is primarily wind-pollinated, as in most Cyperaceae/Schoenoplectus, though various insects may crawl over inflorescences without being key pollinators.
