How to tell it
A shrub half a metre to a metre, with narrow linear leaves, dark green above and white beneath, margins rolled under. White flowers one to two centimetres, with a yellow patch at each petal base, gathered in false umbels at the top. It smells of resin in the heat.
What it is confused with
Yellow halimium
Halimium halimifolium
Flower colour separates them: yellow on common halimium, white with a yellow spot on this. And common halimium's leaves are broad and silvery, this one's are fine like rosemary.
What it is for
No use
It is a pyrophyte: it burns well and comes back fast from the seed bank, which is why it dominates burnt areas. Where there is a lot of halimium, there was a recent fire.
Where it occurs
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.
