Colourful, snapdragon-like tubular flowers of mixed red shades are abundantly borne along tall flower spikes. Also known as Hartweg’s Beardtongue. Foliage is neat, often glossy and unusually evergreen and grows to a height of 90 cm. Flowers appear late spring to mid-summer and continue through to late August.  Often treated as a “hardy annual” in winter climates where a direct autumn sowing blooms in the following summer. In areas where winter snow cover is unreliable, a protective mulch is suggested. Hardy to Zone 5-6 with protection, otherwise approach this plant as a tender perennial best grown as an annual.
