Description
This hardy perennial plant has fleshy roots and grows well in any fresh and deep soil, even in limestone soil. The soil must be well-drained in winter. To plant this species in heavy soil, dig a hole of 30 cm (11.8 in) in all directions, pour in pure sand, and install the stump without adding any soil. All the species and varieties of this plant have deciduous foliage. They are highly tolerant of cold weather, withstanding temperatures as low as -12°C / 10°F approximately. This makes them suitable for many regions. During very harsh winters, covering the stumps with straw or dead leaves is advisable. You can plant this species in the borders of flower beds alongside Crocosmias, Artemisias, and annual Rudbeckias or in the foreground of Ceanothuses, rock roses, Halimiums, Phlomis, etc.
This variety is derived from A. campanulatus, one of the most vigorous varieties. It produces large spikes of flowers in a bright, dark blue colour.

Planting and care
To ensure that your plants can withstand the cold, plant them by covering them with at least 10 cm (3.9 in) of good soil. It is best to plant them in spring and mulch them in winter. If you are growing them in a pot, use 5 young plants for a 24 cm (9.4 in) pot and protect your pots during winter. These plants prefer a rich, moist, and well-drained soil. Water them twice a week during the growth period, but avoid watering them afterwards. Keep in mind that they are sensitive to excessive moisture in winter.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
