Description

Delphinium 'Black Velvet' is a striking spectacle for any UK garden, commanding attention with its tall, stately spires of deep, semi-double flowers. In summer, this larkspur produces densely-packed blooms in a dark purple so rich it seems to drink in the sunlight, creating a dramatic contrast against its fresh green foliage. Delphinium 'Black Velvet' is perfect for adding vertical impact to mixed borders, cottage gardens, or even a bold statement at the back of a perennial bed. Its upright, elegant habit ensures it stands proud while maintaining a sense of refined grace.

Ideal for sunny spots with well-drained soil, Delphinium 'Paramo Black Velvet' rewards careful placement with a long-lasting display of colour. The densely-packed spires of dark purple blooms sway lightly in summer breezes, offering both texture and depth to garden compositions. Delphinium 'Black Velvet' is a showpiece for adding sophistication to borders and cutting gardens alike, while its semi-double blooms provide interest from bud through to fading petals. Whether planted in groups for a dramatic swathe of near-black flowers or mixed with lighter-coloured companions to highlight its rich hues, Delphinium 'Black Velvet' promises an unforgettable summer presence, bringing elegance, height, and a touch of mystery to UK gardens.

Useful information

    • Soak the Delphinium 'Black Velvet' roots in water for 3-6 hours prior to planting

    • Plant your "Larkspur" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
