Do you know how important Carex pensylvanica is to our woodlands? Carex pensylvanica (Oak Sedge or Pennsylvania sedge) is quite possibly the second keystone species next to oaks in the oak woodlands.

Carex pensylvanica deposit mass amounts of organic material in the savanna and woodland ecosystem soils, this spongy organic material hold mass amounts of moisture, water has the highest specific heat of any liquid so it keeps those ground temps very even keel, those even temps and moisture are needed to grow beneficial mycorrhizal fungi, that perfect soil climate also grows ant larvae, ants are major players in woodland flower pollination and seed dispersal,  woodland flowers rely on this pollination and dispersal, woodland ecosystems rely on wildflowers, wildflowers rely on oaks providing shelter and shade, oak woodlands rely on ants, ants rely on Carex pensylvanica, Carex penslyvanica rely on oak woodlands, mycorrhizal fungi connect the whole system through intracate networks of nutrient flow, oak woodlands support the planet, humans rely on the planet as our home 😁

The benefits are not lost in landscaping, Carex pensylvanica (Common Oak Sedge) is one of our favorite native sedges for forming ground covers in part shade situations. Planted densely it can form swirling dense mats of lush grass foliage, which looks good enough to sleep on. Use this native sedge between pavers to great effect or in clumps in dappled light in woodland gardens.
