Gentiana asclepiadea

willowleaf gentian

Outstanding Qualities

Willowleaf gentian is one of the easiest and most satisfying gentians to grow. It produces graceful, arching stems that rise to about 18 to 24 inches and form a loose mound. In midsummer flower buds appear down the center of each stem. In late summer to early autumn they open to rich sky- blue, a color rarely seen in the garden.This handsome perennial is especially effective planted on a slope to create a cascading effect. It looks great with ferns. Mix it with silver-variegated (Brunnera macrophylla 'Jack Frost' or variegated lungworts, for example) or golden-foliage perennials, such as Hakonechloa macra 'Aureola', for dramatic contrast!

Colors & Combos

Great Color Contrasts: silver, variegated gold

Culture Notes

Plant willowleaf gentian in part sun or an open spot with bright shade. It will scorch in full sun. It prefers well-drained, humus-rich soil with average water and suffers if it dries out in the summer.
