Description
Delphinium x cultorum Pacific 'Black Knight', also known as larkspur, is a tall and magnificent perennial plant that produces stunning flower heads in the summer. The flowers, which are deep bluish-violet in colour, are often over 1 metre (3 feet) tall and have a dark black collar at the centre. They are perfect for adding a touch of grandeur to the back of a border, in pots or planters near your house or in bouquets. These larkspurs thrive in sunny locations that have rich, deep and permeable soil.
The 'Pacific Black Knight' Delphinium is a hybrid (x cultorum) obtained by cross-breeding D. elatum, which also gave rise to the famous "Pacific Giant" series. This large herbaceous perennial plant has a short life span but rapid growth. It forms a cluster of deeply cut palmate foliage, tender green in colour, from which floral spikes emerge in summer. The spikes can reach a height of 1 to 1.20 metres (3 to 4 feet) on numerous stems that are 1.8 to 2 metres (6 to 7 feet) tall. The main flowering occurs in June and continues in September if the stems are cut back as they fade. It is highly attractive to pollinating insects. The flowers are single, cup-shaped and arranged on large, upright and sturdy spikes. They have deep bluish-violet petals that surround a black collar, called a 'fly' or 'bee'. The plant grows from a woody rootstock that sinks vertically into the soil.
Delphiniums have a characteristic silhouette that adds dimension, verticality and charm to perennial plant beds. They also make great companions for moss or gallica roses, creating charming and romantic compositions. Another beautiful combination can be created with soft orange daylilies and the baby's breath 'Rosenschleier'. This variety is also perfect for creating flower pots and its flowers hold up well in bouquets.
Note: From March to September, the stems of our delphiniums are pruned short to allow better branching from the base and achieve optimal rooting. This pruning also prevents the stems from breaking during transportation.

Planting and care
To grow healthy delphiniums, plant them in spring after the last frost in a sunny location with soil that is deep, moist, and well-drained. Make sure the soil is not too rich in limestone. Young plants should have at least two or three shoots, while the well-established ones should have five to seven. During the growth period, water the plants once or twice a week and use liquid fertiliser every two or three weeks. To encourage new growth, remove the faded flowers by cutting the spikes at the level of the small side flower shoots. In the fall, cut the entire plant back to ground level.
If you want to add height to your garden, choose these giant plants. They will give structure and balance to the volumes. The taller ones can be planted alone to provide volume and lightness against a dark backdrop of hedges or conifers. The ones of intermediate size will dress up tall flowerbeds, such as those with giant dahlias. Water the plants regularly to keep them healthy, and watch out for slugs.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
