Cyperaceae (Sedge Family)
Ranging from Arkansas and Oklahoma south through Texas and eastern Mexico to Guatemala, Cedar Sedge is named for the plants it most frequently grows among and under: cedars, a.k.a. junipers (Juniperus
species). It is one of many plants evolved to grow in the rich, loose, fast-draining soil created by juniper leaf fall. It is also found in deciduous
woodland where leaves decompose rapidly and as understory to taller grasses in prairies and meadows. Though lawn-grass short, it is a clumping sedge, not forming a proper sod, so it doesnt really make a solid turf, but it can be combined with other low-growing plants to create a natural-looking herb
layer. For central Texas, herb-layer companion plants for the shade would be Cedar Sage (Salvia roemeriana
), Missouri Violet (Viola missouriensis
), Violet Ruellia (Ruellia nudiflora
), Drummonds Ruellia (Ruellia drummondiana
), Baby Blue Eyes (Nemophila phacelioides
), and Straggler Daisy (Calyptocarpus vialis
). It can take occasional mowing and light foot traffic.

AZ , AR , OK , TX Native Distribution:
Oklahoma south to Guatemala Native Habitat:
Prairies, plains, savannahs, meadows, pastures. Mostly in the shade and soil beneath junipers (cedars). USDA Native Status: L48(N)
Growing ConditionsWater Use: Low
Light Requirement: Part Shade
Soil Moisture: Dry
Soil Description: Well-drained loam, clay, caliche, or limestone. Prefers the humus-rich, fast-draining soil under junipers.
Conditions Comments: Generally found in the partial shade of juniper savannah, but also occurs as understory among taller grasses in prairies, where it can get more sun.
Can be used as an accent plant for shade gardens or in full sun. Can comprise part of the herb
layer in regional landscape restorations, particularly under junipers. Interesting Foliage:
