Penstemon grandiflorus, commonly known as large-flowered beardtongue, is an upright herbaceous perennial reaching 2 to 4 feet in height. It features distinctive, thick, blue-green silvery foliage that is smooth and glaucous. In late spring, it produces striking, large, tubular lavender to purple flowers on tall spikes. This drought-tolerant species thrives in full sun and well-drained, sandy, or gritty soils, making it ideal for xeriscaping, rock gardens, and prairie restorations.
