Hypericum kalmianum 'Sunny Boulevard'
Hypericum kalmianum 'Sunny Boulevard' is a compact, rounded deciduous shrub producing masses of cheerful golden-yellow flowers through summer. The bright blooms stand out well against the neat green foliage, creating a fresh and colourful display over a long season.
As the flowers fade, decorative golden-yellow berries develop in autumn, extending the plant's seasonal interest beyond flowering. Its naturally dense, bushy habit makes it particularly useful for adding structure and colour to mixed borders, beds and container planting.
Easy to grow and low maintenance, 'Sunny Boulevard' benefits from being pruned back in early spring to encourage neat, compact growth and plenty of fresh flowering stems for the coming season.
