Differs from ssp. virens :

 

Stems to 100 x 2 – 6 (-8) cm.

 

Rosettes 10 - 25 cm in diameter, strongly branched, forming cushions to 2 m in diameter.

 

Leaves 6 - 25 x 1 - 3.2 (basally 2 - 4) cm.

 

Inflorescence scape 20 - 70 cm, usually farinose, at times green; inflorescence obpyramidal or often cylindrical, branches congested above, scorpioid, usually with 3 - 8 flowers.

 

Flowers : Calyx 4.5 - 7 mm in diameter, corolla 14 - 23 mm in diameter.
