Hydrangea Teller Black Steel Blue 5 Litre Pot

Hydrangea Teller ‘Black Steel Blue’ – Elegant Blue Lacecap Flowers with Dark Stems

Hydrangea Teller ‘Black Steel Blue’ is a refined lacecap hydrangea that combines delicate floral detail with striking, dark stems for a contemporary garden look. Its flat flower heads feature a central cluster of tiny fertile flowers surrounded by larger, rich blue outer florets, creating a soft yet eye-catching display through the summer months.

The deep blue colouring is particularly vivid in acidic soils, where the tones intensify beautifully against the plant’s dark, almost black stems. Glossy green foliage provides a lush backdrop, enhancing both the colour contrast and the overall structure of the plant.

Flowering from early to late summer, ‘Black Steel Blue’ offers a lighter, more natural alternative to traditional mophead hydrangeas, while still delivering strong seasonal impact. Its compact habit makes it ideal for borders, woodland planting, and containers, especially in smaller gardens or shaded courtyards.

Hardy, reliable, and effortlessly stylish, Hydrangea Teller ‘Black Steel Blue’ is a superb choice for gardeners looking to add elegant colour and modern contrast to their planting schemes.
