Aconitum Napellus Alba, commonly known as ‘White Monkshood’, is a striking perennial plant known for its tall spikes of pure white, helmet-shaped flowers. This cultivar typically grows to a height of 1 to 1.5 metres and has deeply lobed, dark green foliage that forms a dense clump at the base.

The flowers bloom in mid to late Summer, standing out against the lush green leaves and adding an elegant, almost ethereal quality to the garden. Despite its beauty, this variety is highly toxic, with all parts of the plant containing potent alkaloids, so care must be taken when handling it. It thrives in well-drained, moist soil and partial shade, making it an ideal choice for woodland gardens or shaded borders.

How to care for your Aconitum Alba

• Sun and shade: Prefers partial shade, but can tolerate full sun in cooler climates. Avoid planting it in areas that receive intense, direct sunlight, as this can cause the plant to wilt and the flowers to fade more quickly.
• Soil: Prefers well-drained soil that is rich in organic matter. It is important to ensure that the soil remains moist but not waterlogged, as this can lead to root rot.
• Watering: Water the plant regularly, especially during periods of drought. However, be sure not to overwater as this can lead to root rot. Water the plant at the base, rather than from above, to prevent the foliage from getting wet, which can cause fungal diseases.
• Fertiliser: Does not require heavy fertilisation. A light application of balanced fertiliser in the early Spring should be sufficient to encourage healthy growth and blooming.
• Mulching: Mulch around the base of the plant to help retain moisture in the soil and suppress weed growth. This will also help to protect the plant from extreme temperatures.
• Pruning: After the flowers have faded, cut back the stems to just above the ground. This will help to prevent the plant from becoming too leggy and encourage bushier growth the following season.
• Propagation: Can be propagated by division in the Spring or Autumn. Simply dig up the plant, separate the clumps, and replant in a well-prepared soil.

By following these basic care guidelines, you can help to ensure that your Aconitum Nepellus Alba remains healthy, vibrant, and blooming year after year.
