DESCRIPTION
Gentiana Asclepiadea - Willow Gentian is said to be one of the easiest gentians to grow. This variety hits about 2 - 3 feet tall. The sapphire blue flowers bloom in small groups on the stems. This plant has won the Award of Garden Merit for being a prized plant for the garden. I have not grown this but it seems to like a bit of shade, from what I have learned.
BLUE WILLOW GENTIAN
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 shade. The plant can be divided after flowering, however it seldom needs this. If sowing the seed indoors then cold treatment is needed
