What it is confused with

Branched asphodel

Asphodelus ramosus

The great asphodel has broad flat strap leaves and a thick, much branched stem to a metre and a half; this has hollow reed leaves and a slender stem. Neither is eaten.

What it is for

It is a clear indicator of degraded, overgrazed soil, and is considered an aggressive invader in Australia and the southern United States, where it was taken from the Peninsula.

Each square is an area with recorded observations of this plant. The lighter background is the set of areas where any of the entries has been observed, and serves as a reference. Note what this is not: it is not where the plant lives, it is where people record it, so trails and towns always look fuller than the mountains. Data from GBIF.
