Heath Wood-Rush

Appearance

Common woodrush grows 10 to 40 cm tall with basal leaves 3.5 to 12 cm long and 2 to 6 mm wide. The flowers have six brown to black tepals 2 to 4 mm long.

Common woodrush is fairly easy to identify with its leaves fringed with long, white hairs and the terminal, spike clusters of 6-parted flowers on variable length stalks, replaced by round capsules starting in late spring. Common woodrush leaves often turn reddish in response to stressful conditions

''Luzula multiflora'' resembles a grass in its vegetative state, but its seeds and scaly tepals are similar to those of other species in the rush family. It is also unusual in preferring upland woodland habitats, as most species in the rush family prefer habitats that are more wet and sunny. The habitat for common woodrush is anthropogenic , forest edges, forests, meadows and fields.

Naming

The taxonomy of the wood rush complex involving several ''Luzula'' spp. has a history of instability. In the past, common woodrush was classified as a variety of a European species, or ''Luzula campestris multiflora''. Both of these species of rush were then also lumped together with another similar species, ''Luzula echinata''.

As a result, ''Luzula multiflora'' and ''Luzula echinata'' are sometimes confused. Most of the many woodrushes that grow in North America are rather difficult to tell apart. In spite of the resemblance of rushes and woodrushes to grasses or sedges, they have the same number and arrangement of flower parts as lilies.

Distribution

It is native to Europe, eastern Asia, northern Africa, northern North America, including Canada, and in northern regions of the United States. The native status of common woodrush is under some debate. While ''Flora of North America'' list it as introduced, the more common opinion is it is a circumpolar species native in North America and in parts of Europe and Asia.
