Gentiana acaulis (jen-tee-AN-ah ay-KAW-lis)

Family: Gentianaceae Unknown Groundcover (<1 ft)

Gentian is an alpine, broadleaf evergreen perennial native to central and southern Europe, and is found in Alpine grasslands, rocky meadows, and subalpine forests at altitudes from 2,500 to 9,700 feet. They have been seen in the mountain ranges of the Alps, Pyrenees, and Carpathians. It is usually found in acidic soils, and sometimes found on chalky limestone or sandstone. It grows 3 to 6 inches tall and 3 to 9 inches wide with a dense, mat-forming habit. The glossy green leaves grow in basal rosettes. Its flowers are solitary, deep gentian blue with a green-spotted throat and form upward-facing trumpets, sitting atop the basal foliage. This plant is a member of the gentian family (Gentianaceae). The genus name, Gentiana , honors King Gentius of Illyria, who reigned from 180 to 163 BC and studied the medicinal uses of plants. The specific epithet acaulis means stemless. Prefers full sun to partial shade, but requires afternoon shade to protect the plant from leaf bleaching. Thrives in moist, well-drained, gritty, slightly acidic soil and prefers cool summer climates. It is winter hardy in zones 3a to 7a. It would be intolerant of the hot, humid conditions of Eastern North Carolina. Best propagated by seeds or division. Gentian is primarily an ornamental plant. Gardeners might enjoy this alpine native in a patio container, as a ground cover, in a rock garden, or in a cottage garden. The challenge will be to find a place where this plant would be happy, and that is similar to its native habitat. Diseases, Pests, and Other Plant Problems: No serious insect pests or diseases. Monitor for slugs and snails. May be susceptible to root rot. The plant can not tolerate hot or humid conditions.
