Aconitum carmichaelii 'Arendsii' - 2026

Aconitum carmichaelii 'Arendsii' is a bold late-flowering perennial, admired for its tall spires of rich violet-blue hooded blooms that appear from late summer into autumn. Rising above sturdy stems with divided dark green foliage, these flowers bring striking vertical interest and a deep splash of colour when many other perennials are fading. Perfect for the back of borders, this variety combines beautifully with ornamental grasses and autumn perennials, making it a standout choice for extending seasonal interest in the garden.

Thriving in moist, fertile, and well-drained soil, Aconitum carmichaelii 'Arendsii' prefers partial shade but can tolerate full sun in cooler regions. Hardy and reliable, it requires minimal care once established. Its nectar-rich blooms are highly attractive to pollinators, especially bees, helping to support wildlife late in the season. Like all aconitums, it should be handled with care as all parts of the plant are toxic if ingested.
