Hosta ‘Devon Green’ Description

Hosta ‘Devon Green’ is a refined green hosta valued for its glossy leaves, neat habit, and elegant simplicity. It forms a polished mound of dark green, heart-shaped foliage with good substance and a smooth, lustrous surface that adds depth and contrast in shade. Grown in partial shade with moist, fertile, well-drained soil, it is useful in formal borders, containers, woodland gardens, and as a companion to variegated or blue hostas where a rich green foil is needed. In summer, lavender flowers rise above the foliage and provide a soft seasonal accent. For gardeners looking for a dependable dark green hosta with shine, structure, and understated beauty, Hosta ‘Devon Green’ is a refined selection.
