    The Aconitum, also known as the Aconite, Wolf’s-bane and Monkshood are poisonous plants with tall, spiky flower heads and deeply loved foliage. The Aconitum carmichaelii ‘Arendsii’ (Monkshood) is about 2 – 3 feet tall; a sturdy plant with thick, 3-loved leaves and deep-blue, hooded flowers borne in spikes from late summer through fall.

    Planting Tips

    Their thick fleshy roots dislike disturbance. Plant them in spring or fall in rich, moist, but well-drained soil. The roots are brittle; do not disturb the plants unless they become overcrowded. Site them where they can get afternoon shade.

    Landscape Ideas:

    Monkshoods are tall, spiky plants that are best for the back of the border. Plant them with late-blooming perennials such as Sweet Joe-Pye-weed (Eupatorium purpureum), Russian sage (Perovskia atriplicifolia), and asters.
