Distribution

This sedge is native to much of North America, including the southern half of Canada and most of the continental United States, from California to Maine.[1] Carex scoparia can be found in many types of wetland habitat, from meadows to irrigation ditches, though it is adaptable to varying soils and hydrologic conditions. It is an introduced species in New Zealand and parts of Europe.

Description

Carex scoparia produces dense clumps of stems 20 centimeters to one meter tall with narrow grasslike leaves up to about 30 centimeters long. The inflorescence is a cluster or open array of several bullet-shaped spikes of flowers. The spikes are light green and age to tan or brown. The fruit is covered in a sac called a perigynium which is light in color. The achene within the perigynium is ovate or elliptic.

gollark: So you can stick some control room INSIDE the reactor with no negative impact.
gollark: A great part of this design is that it doesn't need wall adjacency.
gollark: The planner won't run on my system so I design ingame.
gollark: I have a 1000% design. If I could be bothered to expand it to 24x24x24 I'd expect >1200%.
gollark: Also, just run four buffers in at the corners (it's active diamond right?)
