AppearanceOne 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 60-90cm in length. Trumpet-shaped, deep blue flowers occur in late summer into autumn.
PredatorsThis plant suffers from spider mites, slugs, snails and aphids.
UsesLike many members of the genus and indeed the family Gentianaceae, the roots have a close association with certain fungi in a similar way to the Orchidaceae and Ericaceae though of course completely unrelated to both of these families. 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 shade. The plant can be divided after flowering, however it seldom needs this. Propagate by seed sown as soon as the seed is ripe into a cold frame. If sowing the seed indoors then cold treatment is needed.
''G. asclepiadea'' has gained the Royal Horticultural Society's Award of Garden Merit.
