The classic autumn Gentian, striking blue trumpets.
The classic autumn-flowering Gentian and the best known. Large, blue, trumpet flowers held above mats of green foliage for most of September and October - they really are one of the glories of the autumn garden, providing such a rich intensity of colour when most other plants have finished their displays.
An acid (lime-free) soil that is well-drained but moisture retentive is ideal - a slightly leafy (leaf mould) or peaty soil suits them well. They prefer sunshine but will do well enough in very light or partial shade. If you have chalky, limy, alkaline soil then grow them in a large container with acid ('ericaceous') compost and keep them watered - they grow and flower well with this.
