Knotsheath Sedge makes for a great addition to any home.
Knotsheath Sedge, also known as Carex retrorse and deflexed bottlebrush sedge, is of the family Cyperaceae, and are monocotyledonous flowering plants from a division of the Poales order. There are an estimated 5,000 species spreading across every continent, save for Antarctica, with around 600 varieties of the sedge in North America alone, commonly found on a line forming from Oregon and Washington on the west coast to New York on the east coast and all points north.
This sedge has a lovely green color which butterflies love.
The sedge is grouped into sections of common traits. The knotsheath sedge is part of the Vesicariae group, featuring clump-forming, underground stemming with root and shoot producing nodes, brown or reddish purple basal sheaths, sheaths with cross partitions between the veins (septate-nodulose), hairless leaves, sheaths split into fibers, forming a ladder shape, 2-10 spikes, terminal spike all-staminate, leaf-like bract subtending the lowest pistillate spike, mostly ascending perigynia. The 3-sided achenes are hairless, egg to teardrop-shaped, beaked and toothed and somewhat inflated.
From one of the 10 largest flowering plant families, the knotsheath sedge reaches anywhere from 4-40 inches in height and achieves fruiting from June to August. The pistillate spikes that are so readily identifiable on this plant, form clusters of seeds (achenes). Each cluster is wrapped in a casing (perigynium), supported by a scale. The casings are widely spread to angle downward and are tightly packed along the spike. Each of the pistillate spikes will contain 20-150 fruits.
Because it thrives in northern climes, the sedge grows best in a habitat featuring part to full shade, little to no direct sun, and wet surroundings; sedge meadows, wet thickets and ditches, swamps, and near lake or pond shores are ideal for growth. The knotsheath sedge is known for its beautiful shade of green, attracting butterflies and other wildlife. Increasingly popular with gardening enthusiasts, sedge makes a wonderful addition to well-planned gardens and landscaping, adding movement and a unique touch to any design.
