Description
The Delphinium grandiflorum Blue Diamonds, also known as Chinese Larkspur, is a variety that has preserved the charm of wild plants. It produces light blue flowers throughout the summer on a dense plant that is resistant to bad weather, with highly dissected foliage, perfect for rocky gardens. This weather-resistant plant does not require staking. It thrives in sunny locations with moist soil. Indispensable at the front of perennial borders, in containers, in flower pots near the house, or in bouquets, these plants flourish in the sun in humus-bearing and permeable soils.
The Delphinium Blue Diamonds, or Chinese Delphinium, is one of the many hybrids obtained by cross-breeding D. grandiflorum, which is native to mountainous regions of China, Siberia, Mongolia, and Japan. It is theoretically a perennial plant, but is most often cultivated as an annual. It is hardy and shows rapid growth, forming a dense clump, 34 to 40 cm (13.4 - 15.7 in) wide, with highly dissected palmate foliage in tender green, from which numerous floral spikes, 50 cm (19.7 in) in height, emerge in the summer. Flowering occurs from June to September and is highly visited by pollinating insects. The flowers are single, cup-shaped, arranged on large, erect, well-ventilated spikes, and display five petals of a blue color that can be seen from afar, with the upper petal having a spur. The plant develops from a woody rootstock that extends vertically into the soil.
The characteristic silhouette of Delphiniums always adds volume, verticality, and a lot of charm to perennial borders. The 'Blue Diamonds' selection allows for the quick creation of an elegant and rustic setting by sowing directly in the ground. Its intense blue color is precious, enlarging the space and highlighting small areas. When combined with white, its shade is gentle; a marriage with yellow or orange is more dynamic. Delphiniums are also great companions for moss or gallica roses, with which they create charming and romantic scenes.

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.
