Originating from South Africa
Spectacularly lustrous and vigorous, upright and architectural. Lush and broadly sword-shaped herbaceous leaves emerge from slowly spreading fleshy roots, called corms. The foliage emerges as stiffly upright stems from which the broad leaf blades fan out, making an impressive spiky looking display before the flowers emerge.
As the bright green leaves mature, the dark burgundy/black stemmed flower spikes begin to emerge, each one with copious stunning burgundy and dusky red buds borne in two chevron shaped ranks. The widely flared, incredibly intense vermillion trumpet-shaped flowers have deeper burgundy throats and open in succession along the flower spike, making a display lasting for many weeks.
Easy to grow in any well-drained soil in sun or light shade. Height and spread after 2 – 5 years 1.5m x 50cm.
