Penstemon hartwegii
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 90cm (36"). 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.
How to Grow
Half hardy perennial that requires a winter mulch in areas of severe cold and little snow cover. Indoors sow seed in a soil-less mix in mid-March. Germinate seed at 18-20C (65-70F) for 10-15 days. Grow on under lights then harden off and transplant to a sunny site with rich, well drained soil. Direct garden seeding can also be done in Fall. Space plants 30cm (12") apart in the garden.
