Description
The Agapanthus Double Diamond is a new variety known for its compact size and stunning pure white double flowers. It blooms from July to August, producing beautiful globular umbels of flowers around 10cm (3.9 inches) in diameter. The flowers are carried on short stems, only about 30cm (11.8 inches) in height. The trumpet-shaped double flowers are pure white, and when cut and placed in a vase, they can bring freshness to any home. The foliage of the agapanthus is evergreen, especially in mild climates and remains decorative throughout the year.
This plant is not hardy and cannot tolerate temperatures below -5°C. Planting the Agapanthus Double Diamond in a pot placed on a sunny terrace to ensure abundant flowering is best. If you're planting it in the ground, choose a warm exposure in a mixed border, perennial bed, or border. It can also be grown on its own. This plant thrives by the seaside, in an English cottage, and even in a city garden.

Planting and care
The Double Diamond Agapanthus needs to be grown in a warm, protected location and faces south, getting full sun. The plant can endure drought well, but it requires rich, moist soil and particularly well-drained soil during winter. Water it twice a week in the growing season, but do not water it while it is dormant. During winter, the Agapanthus is susceptible to excessive moisture and doesn't like waterlogged soil. Therefore, it's recommended to mulch the base with a 20 cm (7.9 in) thick layer of dead leaves over the base of the plant and cover it with a mesh to prevent wind damage. Snow is also an excellent protection against excessive moisture and cold. Bring the plant indoors for protection if you're planting the Agapanthus in a pot. When planting it, ensure the fleshy roots are covered with leaf compost and planted at a depth of 30 cm (11.8 in). Once it's established in the ground, avoid disturbing it. In autumn, remove dead leaves and trim the faded stems so the plant doesn't exhaust itself by producing seeds.

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.
