One of the larger species within the genus, it produces pairs of leaves, sometimes whorled in threes or fours around particularly vigorous shoots on stems that generally arch elegantly outward from the base of the plant between 60-90 cm (2.0-3.0 ft) in length. Trumpet-shaped, deep blue flowers occur in late summer into autumn.

This particular species is relatively easy to grow in most garden situations as long as it has plenty of organic material added to the soil.

Gentiana asclepiadea likes moist, rich, well-drained soil in full sun or partial . The plant can be divided after flowering, however it seldom needs this. If sowing the seed indoors then cold treatment is needed (see germination information below).

Gentiana asclepiadea has gained the Royal Horticultural Society's Award of Garden Merit.
