Schoenoplectus tabernaemontani is best grown in standing water (up to 12” deep) or in wet soils in full sun. Tolerates very light shade. In large water gardens, it may be grown in submerged containers. May also be planted in the mud at the margins of ponds or streams or in bog gardens. Clumps may be divided in spring. Naturalizes by creeping rhizomes, and, if left undisturbed in optimum growing conditions, will spread sometimes aggressively to form dense colonies. Keep in pots in large rain gardens or bog gardens or on the edges of ponds or streams to stabilize soil.
 
The new shoots and young roots may be eaten raw or cooked. The older roots can be made into flour.
