Penstemon strictus, Rocky Mountain Beartongue: Found in the western part of North America this is one of the longest lived and easily grown of the Penstemons.  A fabulous evergreen perennial that bares multiple spires of large royal blue to purple hooded flowers during the summer months. The two lobes of the upper lips project over the lower lip lobes giving the hooded effect. It spreads steadily by stolons to form a large attractive evergreen clump making a perfect weed suppressing ground cover. Penstemon strictus will tolerate heavy and moist soils better than most of the Penstemons but prefers dry, light , well drained soil. Enjoys full sun and is perfect for a rock garden. 60 cm H x 80 cm W.

Sowing Advice

Sow  Penstemon seeds in good quality seed raising mix at any time. Lightly cover with vermiculite or mix to their own depth. Although we recommend that P. Strictus be sown in early winter  and placed out doors so as to experience temperature fluctuations, once the weather begins to warm up place in a propagator or cover with a plastic lid in a warm place. We suggest germinating at 15-20 degrees C.  keep moist at all times, but do not saturate. Pot on seedlings to harden off and mature before finally planting out in the garden.
