One of the most spectacular rock garden plants, award-winning Gentiana acaulis (Stemless Gentian) is an evergreen alpine perennial forming a slowly spreading mat of glossy, deep green, elliptical leaves. Sitting directly on top of the foliage, large, solitary rich blue, trumpet-shaped flowers bloom in late spring to early summer. Facing upward, they reveal green-spotted throats. Noted for its preference for cool-summer climates, this stunningly attractive plant is perfect for rock gardens or as a groundcover. The conspicuous beauty of its true blue color will not be passed by unnoticed!
