About this plant
Calluna vulgaris 'Silver Knight' is a compact evergreen shrub known for its silvery-gray foliage and delicate blooms. In late summer to early autumn, it produces an abundance of soft lavender-pink flowers that contrast beautifully with the muted tones of its foliage. During winter, the foliage takes on purple tints, adding seasonal interest to gardens even in colder months.
Originating from the moorlands of Europe, this cultivar was selected for its unique foliage and ability to thrive in challenging conditions. 'Silver Knight' is an excellent choice for rock gardens, borders, or as ground cover, where its year-round color and fine texture contribute to a refined and naturalistic aesthetic.

Design tip
Incorporate this heather into planting designs that rely on foliage as much as flowers for visual impact. Its cool silver tones provide a restful contrast, helping brighter blooms and richer greens appear more vibrant without competing for attention.
