Penstemon barbartus Twizzle

This graceful hardy perennial is a far cry from the showy, large-flowered varieties that most gardeners are familiar with. It was bred to preserve the natural beauty of the American native Penstemon barbartus, with slender, tall stems and narrow, tubular flowers. The blooms are borne in clusters from each leaf axil, creating a prolific display that will last the whole summer. Penstemon barbartus ‘Twizzle’ is quietly elegant, bringing a relaxed, natural-looking display to herbaceous borders. Height: 70cm (28). Spread: 40cm (16).
