Cultivation Details

HabitPerennial
Growth—

The plant is best adapted to slightly acidic to somewhat alkaline conditions tolerating pH levels from 5.7 - 7.4. They are also tolerant of medium levels of salinity[1]. The plant tolerates alkaline conditions well[1]. It can handle standing water for periods of 2 - 3 months so long as there are periods where the soils dry. The sites where it is found rarely have the water table drop more than 100cm below the root zone late in the growing season[1].

Propagation

Seed - sow in situ in the spring in a moist soil in light shade. If seed is in short supply it can be sown in a cold frame and be planted out in the summer. The seed usually germinates in 2 - 6 weeks at 15°c[2]. Species in this genus, when started from seed tend to stay diminutive for over a year, with plant leaves remaining stunted and fragile for a considerable period of time[1]. Division in spring[3]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Carex+nebrascensis>
