The spiny cushion of the high limestone sierras, so compact and so hard you could sit on it without crushing it. In May it covers itself in violet-blue flowers, and it is one of the most surprising sights in the Iberian mountains.

Where it grows

Uplands

Also known as

blue broom, branch thorn

In flower

How to tell it

A hemispherical, grey, rigid cushion of interwoven branches all ending in spines. Tiny, short-lived leaves. Violet-blue pea flowers emerging straight from among the spines. Only at altitude, above a thousand metres.

What it is confused with

No dangerous lookalikes known in the Iberian Peninsula.

What it is for

None. The cushion form is an answer to wind, frost and grazing: inside it creates its own microclimate, and many rare mountain plants germinate under these cushions.
