Bulbous rush (Juncus bulbosus) presents me with something of a problem! I cannot find anything interesting to say about it!
It is a small plant, it has multiple stems coming from a central root bulb and has small crusty flowers! It can be quite variable but generally the stems are brownish red with some green apparent. It is, though, a rather dull, insignificant plant!
It is common and grows in both damp and wet conditions but I most frequently encounter on exposed, muddy ground on heathland paths where it seems to tolerate people's footsteps with not trouble at all. It can also be found in pools and bogs - it just needs to be wet!
That is about it ... I can find no interesting fact or fiction to add!
