South Africa. Fabulous architectural glaucous foliage, jaggedly cut. Hardy once established. Likes sun & drainage. 1-2m. Weedy in some areas as it spreads by suckers. Restrained for me in Canterbury where I use it in the nastiest, driest places. Large plants. Use up the space of four little ones for freight .
Flower heads: Close up Stan Shebs. Full bloom in Jardin des Plantes in early Spring. Full plant in the wild by SAplants Wikimedia Commons
