Carex brizoides aka Alpine Grass

Carex brizoides is known as quaking sedge. It is a perennial, a plant that lives for years. It belongs to Cyperaceae, the sedge family. Its native range centres on central and southern Europe. It also grows in Turkey and elsewhere in Europe. This includes parts of western, eastern, and southeastern Europe. The RHS lists it as non-native to Britain and Ireland. In the wild, it grows in damp, shady places.

The records give no sound height or spread at maturity. They give no stem or leaf details for this species. Each plant bears both male and female flowers. Each flower is either male or female, not both. Wind moves pollen from flower to flower. The evidence gives no bloom months or fruit details. Chicago Botanic Garden also lists it as a perennial.

Plants For A Future lists moist or wet soil as suitable. It lists sand, loam, and clay as soil choices. The soil can be mildly acid, neutral, or mildly alkaline. The plant can grow in light shade or full sun. These needs fit the damp sites in its range. The source suggests woods with dappled shade and bog gardens. It gives no firm hardiness zone for this species. Based on its range, it expects survival outdoors across much of Britain. This is not a hardiness rating based on tests.

Plants For A Future describes how to grow more from seed or division. Sow seed in spring, in moist soil with light shade. Start small seed batches in a cold frame. The source says seeds sprout within two to six weeks at 15°C. Plants from this sowing can move outside in summer. Split well-grown plants in spring, a method called division. Large divisions can go straight into their final sites. Grow small ones under cover until their roots grow well. Plant these out in summer or the next spring.

The leaves have a recorded use as packing material. Plants For A Future lists cooked roots and seeds as edible. It gives few details on how to prepare or use the seeds. Their small size makes them hard to handle. The source gives this plant a low food-use rating. It records no uses in medicine and no known hazards. That hazard note does not prove safety for every use. The evidence names no pests or diseases linked to this species.
