Deep blue thistle-like flowers on robust, stiff, branched stems in July and August above clumps of silver-veined, dark grey-green leaves. Similar to Eryngium bourgatii 'Picos Blue' but flowers have a more purple tint and are more serrated and divided.

Well drained soil in full sun. Drought tolerant. Established plants form deep tap roots and dislike disturbance.

From root cuttings. Also by division but this can be tricky.
