Description
The collection includes:
- x 1 Monkshood (Aconitum napellus): the wild montane species with deep indigo blue flowers, blooming from late June to late August. It reaches a height of 90cm (35in) to 1.20m (4ft) when in flower.
- x 1 White Monkshood (Aconitum napellus 'Album'): a beautiful form producing white flowers with hints of grayish-pink. Like the wild species, it flowers from late June to August and reaches a height of 90cm (35in) to 1.20m (4ft) when in flower.
- x 1 Spark's Variety Monkshood (Aconitum henryi): a horticultural variety that can reach a height of 1.50m (5ft) when in flower. It blooms slightly later than the previous two, from September to October. Its flowers are dark blue-violet to deep midnight blue.
Plant them in February-March or October-November, in a rich and well-drained soil that remains slightly moist in summer, in partial shade or non-scorching sun (preferably morning sun). A mixture of compost, peat, and garden soil in equal parts will be suitable. Be aware of windy exposures that can damage their tall flower spikes. Stake the tallest flower spikes to prevent them from bending. Allow 3 to 4 plants per square metre, with a minimum spacing of 50cm (20in) between plants or with other plants. The deciduous foliage of the aconites emerges from the ground each spring and dries up in autumn. Their roots can withstand temperatures as low as -23°C (-9.4°F).
The tall stature of Aconitum makes them perfect for the back of perennial borders, especially with foxgloves and black cohosh (Actaea or Cimicifuga) for enchanting scenes in partial shade. They can also be planted among bushes for support, for example, in the company of Japanese anemones 'Septemberglanz' and 'Queen Charlotte' which bloom from August to October. They also look stunning in front of the dark foliage of Physocarpus 'Rubella' or 'Midnight' for example. They are good perennials for light and cool woodland areas. Their flowers are beautiful in bouquets.

Planting and care
Attention, all parts of the aconite are toxic if ingested (anesthetic) or in contact with the skin, do not plant it near vegetables or in areas frequented by children, and avoid high traffic areas. Use gloves when handling it and wash your hands afterwards. Aconites thrive in light understory, in a sheltered location away from strong winds. They are planted in deep, rich soil that remains slightly moist in summer. These plants tolerate sunlight, but the soil must be consistently moist and never allowed to dry out. For this reason, it is recommended to use mulch in summer to maintain some freshness. The soil should be mixed with compost, good quality potting soil, and turf. Stake the taller flower spikes to prevent them from bending. Beware, aconite is toxic.

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.
