Penstemon heterophyllus ‘Züriblau’
at Digging Dog
Beard Tongue
Among the most exuberantly blooming plants this side of the Mississippi, Penstemon is part of the enchantment of the West. A member of the Snapdragon family, even cultivated varieties retain a natural air, with dainty, long trumpet flowers and five (pent) prominent stamens.
Sturdy and easily grown, species vary from 1 to 5 ft. tall, and range in color from white to pink to purple to deep wine redone for every sunny spot. Trim after the first bloom to encourage a repeat flowering, and cut to the crown in winter for bushy growth next season. Penstemon heterophyllus ‘Züriblau’ 
Colored with many shades of blue, this handsome, bushy Penstemon offers soothing tones. Topping the narrow, bluish green foliage and red-hued stems, short, showy spikes bear a profusion of slim, bright blue tubular flowers, which look exquisite against silver-leafed Veronica ‘Silbersee’.
Blooms June–August. Size: 20" high x 18" wide; hardy to zone 5. Penstemon heterophyllus ‘Züriblau’ (P-0207)
