Common Oak Sedge Seeds

Carex pensylvanica

  • HOW TO GROW
  • FAST FACTS

HOW TO GROW

Sowing: Direct sow either in late fall or early spring. Plant the seed just below the surface of the soil, compacting the soil very firmly. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting. Keep the soil lightly moist until germination, since this seed cannot germinate in dry soil.

Growing: Water seedlings regularly until they become established. This plant thrives in moist soil, though it also grows well in dry soil and tolerates drought. It adapts well to various soil types including sand, poor soil, and clay. This plant eventually spreads by rhizomes, and mature plants may be divided. It makes an excellent choice for a shade groundcover, as well as being popular as a turfgrass.

Seed Saving: At the end of the season, the seed heads will begin to turn from green to brown. Remove them as soon as they ripen to their mature brown color, and spread them out to dry. Thresh them to separate the seed from the stems. Store the seed in a cool, dry place.

DESCRIPTION

This miniature sedge is often sought for woodland plantings where a short native grassy plant is desired. Pennsylvania sedge seeds are very difficult to harvest, so they are typically either very expensive or simply not available. Finding a natural stand of this sedge in the woods is a rare and beautiful thing.
The low stature and delicate, attractive growth of this plant make it a popular choice as a turfgrass or for landscaping. Renowned botanist Carl Linnaeus first included this species among the sedge plants in his landmark publication Species Plantarum. Carex Pensylvanica came from the name ""Carex"" comes from a Greek word meaning ""to cut,"" referring to the distinctive sharp edges of most sedges.
