Growing Gentian
Gentian grows best in moist, rich, cool, well-drained soil and part shade. It thrives in planting locations that receive morning sun and afternoon shade. Because this wildflower grows best in cool summer conditions, it often struggles in areas south of Zone 7. When planted in its preferred growing conditions, gentian will spread to form a colony of long-lived plants. Gentian is tough to start from seed, because germination is erratic at best. You may be better off transplanting potted specimens into your garden. Nursery-grown transplants are sometimes difficult to find, so check with local nurseries that specialize in native plants. Water the transplanted gentian plants regularly for the first growing season to promote a strong, deep root system. Cover the soil around the plants with a 2-inch-thick layer of mulch to prevent soil-moisture loss.
