Has grey-green to azure-blue flowers that darken as the season progresses. Stems suffused with a similar colour.

Leaves deeply lobed with vicious-looking spines that are relatively harmless. Grey-green variegated leaves.

A hemi-globed silvery-grey set of disc-florets sits atop about 12 or so azure-blue, long, narrow and pointed 'ray-florets' (which in this case are actually bracts/leaves, not florets). Stems branched and shallowly ribbed in places. Stem leaves dark grey-green with pale-green/whitish central marks blending into steel-blue.

Marrow 'ray-florets' (coloured bracts) have un-sharp pointed tips.

Leaves variegated dark-green to pale-green/white in the centre.

Leaves multi-lobed, triangular angled ending in un-sharp tips.


Easily confused with : other garden Sea-hollies, but most do not have variegated leaves, or quite the same multi-lobed sharp-pointed teeth.

Some similarities to : Sea-Holly (Eryngium maritimum) which has greyer-green leaves that are not variegated and dull-yellow-green to azure-blue disc-florets without ray florets. The collar around the disc-florets of Sea-Holly are not narrow, but rather more like a starred collar. Sea-Holly grows extensively wild in the UK around the coast, whereas Meditteranean Sea-Holly does not.

Far more likely to be found in a garden or very nearby than growing in the wild. Grows wild in the Mediterranean and presumably also in the Pyrenees. It is one of the many atypical Umbellifers lacking a recognisable umbel of flowers.

THREE POLYYNES


The roots of the plant yields three poisonous polyacetylenes (polyynes), such as Falcarinone, Falcarinol and Falcarinolone as well as Scopoletin, a coumarin. The Falcarinolone may be present only as an artefact derived from the auto-oxidation of Falcarindiol, assuming the latter is also present.
