Gentians are prized for their tubular flowers in intense blue shades. Many are considered difficult to grow, but G. asclepiadea needs little more than consistent moisture and humus-rich soil with excellent drainage. Some require lime-free soil, as noted. Well worth the extra care, as they produce some of the richest blues in the garden.
