Description
Aconite carmichaelii 'Arendsii' or Carmichael's Monkshood is a perennial that forms an upright clump. Its flowering occurs later in the year, from September to October. This allows it to bring cheer to the garden as one of the few plants that blooms during this period. Very floriferous, its upright and rigid stems bear clusters of numerous large flowers. These clusters measure 20cm (8in) in height. The flowers, shaped like an ancient helmet, take on a bluish-purple hue. It attracts bees and makes the plant melliferous, meaning it contains substances collected by pollinating insects or some birds that will turn into honey.
The foliage of Aconitum carmichaelii is deciduous. With a shiny dark green colour, the veined leaves are deeply divided into 3 to 5 lobes. This broad foliage somewhat resembles that of Delphinium. Originating from Russia to China, it is a very hardy plant. It can reach a height of 1.20m (4ft). It is a tall plant.
Its flowers are delightful as cut flowers. The Blue Monkshood is most often cultivated against a backdrop of flower beds, as well as among bushes sheltered from the wind or against a wall. It is a plant of the undergrowth that is also found on the edge and even in open spaces. It pairs well with Japanese anemones, asters, or plants with autumn foliage. It can also be placed next to late-season plants such as yellow-flowered Rudbeckias. It blends perfectly with white valerian. Known as Jupiter's Helmet, it is a medicinal plant with antispasmodic properties. It is also highly toxic in all its parts, especially the roots.

Planting and care
Aconitum carmichaelii 'Arendsii' thrives in partial shade in moist soil. It does not tolerate dry soil. If you want to grow it in full sun, the soil must be kept moist to ensure the flowers bloom. Plant Aconites at a depth of 5cm (2in), spaced 50cm (20in) apart. Provide support if the wind damages them. Remove faded flowers during flowering to prolong it. Once the flowering is finished and the clump is no longer decorative, cut back the withered stems. This perennial can suffer from root rot in heavy soil and from verticillium (fungi). It can be attacked by aphids. It is a very easy plant to grow.

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.
