Penstemon barbatus 'Pristine Scarlet' is a vivid, easy-care beardtongue that brings strong vertical color to sunny beds and borders. You will get sturdy stems topped with tubular scarlet-red flowers that are especially attractive to hummingbirds.
Plant it in full sun for best flowering, and choose well-drained soil. If your site tends to stay wet in winter or after heavy rain, improve drainage before planting to help avoid rot and decline.
Once established, you can expect good drought tolerance, making it a smart choice for water-wise plantings. During the first growing season, water regularly to help roots settle in, then reduce watering as the plant matures and weather allows.
To keep the display going, remove spent flower spikes as blooms fade. After flowering, you can tidy stems back toward the basal foliage to refresh the look and encourage strong regrowth. Mature size is about 16-18 inches tall with a 14-16 inch spread.
