About

Gentiana alba (called plain, pale, white, cream, or yellow gentian) is a herbaceous species of flowering plant in the Gentian family Gentianaceae, producing yellowish-white colored flowers from thick white taproots. It is native to North America from Manitoba through Ontario in the north, south to Oklahoma, Arkansas and North Carolina, and it is listed as rare, endangered, threatened or extirpated in parts of this range. This species resembles bottle gentian (Gentiana andrewsii), which has blue flowers and a less upright habit, and shares much of the same range. Gentiana alba starts to bloom a few weeks earlier than bottle gentian and the flowers are more open at the tops. Grow it in full sun and partial shade and loam and sand soil. In UK gardens it is hardy in most of the UK (RHS H5). It works well for rock garden, container and border. It tolerates acid and neutral soils, moist but well-drained conditions and east-facing, south-facing and west-facing aspects.
