Hypericum kalmianum ‘Blue Velvet’ brings cheerful colour and elegant texture to any garden space. This resilient shrub thrives in various conditions, making it an excellent choice for both experienced and novice gardeners. Its distinctive blue-green leaves contrast beautifully with its golden blooms, ensuring visual appeal through much of the growing season. This plant offers a lovely, low-maintenance option for creating vibrant garden displays.
Hypericum kalmianum is named after Pehr Kalm, a Swedish botanist who explored North America. This particular cultivar, ‘Blue Velvet’, earns its name from its strikingly attractive blue-green leaves. These leaves have a soft, almost velvety appearance, setting it apart from other Hypericum varieties. The plant forms a neat, rounded shrub, adding structure and year-round interest to borders or mixed plantings. Consequently, gardeners often choose it for its robust nature and consistent performance in the British climate.
During summer and early autumn, Hypericum kalmianum ‘Blue Velvet’ produces bright yellow, cup-shaped flowers. Each bloom features long, golden stamens, giving them a soft, fluffy look. These cheerful flowers stand out wonderfully against the plant’s distinctive foliage. The lance-shaped leaves are a true blue-green, offering a cool contrast to the warm yellow flowers. These leaves remain attractive, providing continuous visual appeal.
This versatile shrub fits well into many garden designs. You can use it to edge borders, create low hedges, or simply as a specimen plant. It also works brilliantly in rockeries or larger container displays. Plant it in groups for a mass planting effect, filling awkward gaps with colour and texture.
For optimum growth and flowering, prune Hypericum kalmianum ‘Blue Velvet’ in early spring. First, remove any dead or weak stems. Then, cut back about one-third of the previous year’s growth. This encourages a bushy habit and abundant new flowers. This simple task maintains the plant’s vigour.
This plant is a true asset for UK garden wildlife. Its bright, open flowers are very attractive to various pollinators. Bees, for example, visit frequently, collecting pollen and nectar. Butterflies also enjoy these vibrant blooms, adding more movement and colour to your garden. Furthermore, the dense foliage provides shelter for small garden creatures. By including Hypericum kalmianum ‘Blue Velvet’ in your planting scheme, you actively support local biodiversity, creating a healthier and more lively outdoor space.
Hardy in all of the UK and northern Europe. Suitable for exposed sites.
Regular watering during establishment. Once settled, it becomes more drought tolerant. Prune in early spring by removing any dead or weak stems and cutting back approximately one-third of the previous year's growth. This encourages a bushy habit and promotes a profusion of new flowers. Fertilise lightly with a balanced feed in spring if the soil is poor.
This plant is deciduous so it will lose all of its leaves in the autumn and get fresh new foliage each spring.
