How do you identify Cyperaceae?
Rush stems (Juncaceae) are generally circular in cross section, while the stems of sedges (Cyperaceae) are typically three-sided (triangular). Cross-section of a sedge, ―Sedges have edges‖. Grasses are round in cross section and generally have hollow internodes.
Is Cyperaceae a herb?
Family: Cyperaceae Sedges are perennial or annual grass-like herbs (they are not actual grasses), with stems that often are three-sided. The leaves are arranged such that they spiral around the stem in 3- ranks and have a basal portion that sheaths the stem.
Are grasses Graminoids?
Graminoids such as grasses, sedges, and rushes are well represented in prairies. Grasses—the most dominant graminoid in prairies— have evolved to thrive with grazing animals. In most plants, the growth of the plant occurs at its branch tips.
Is sedge grass invasive?

How do you identify a graminoid?
In botany and ecology, graminoid refers to a herbaceous plant with a grass-like morphology, i.e. elongated culms with long, blade-like leaves. They are contrasted to forbs, herbaceous plants without grass-like features.
Are Graminoids herbs?
Graminoid: A non-aquatic, flowering herb with relatively long, narrow leaves and inconspicuous flowers with parts reduced to bracts. This includes grasses, sedges, rushes, arrowgrasses and quillworts. Grassland: Vegetation dominated by graminoid vegetation greater than 50 percent of total herbaceous canopy cover).
Should sedge be cut back?
Sedges resent being cut back too hard, so if the foliage lasts through the year untattered, just leave it alone. If the older foliage looks messy, or the tips have been burned by winter cold, trim the sedge back modestly, by no more than a third at most, in March or April.
