  • Aconitum ‘Arendsii’ is a striking perennial prized for its deep, dark blue flowers, which rise elegantly on tall spikes above lush green foliage. Best planted in autumn, this variety establishes strongly and delivers an impressive floral display in the garden.

  • This shade-loving perennial thrives in cooler, partially shaded areas, making it ideal for woodland gardens, shaded borders and areas where other flowering plants may struggle. Its upright growth habit adds height and drama, creating a bold contrast against surrounding foliage.

  • Aconitum ‘Arendsii’ is also pollinator friendly, attracting beneficial insects while helping to deter certain unwanted garden pests. Supplied as a bare root plant, it is easy to establish and offers long-lasting structure and beauty to shaded garden spaces.

    • Light Required Full sun to partial shade.

    Watering Keep the soil consistently moist during the first growing season. Once established, water when the top inch of soil is dry. Avoid overwatering.

    Best Growing Conditions Plant in moist, well-drained soil in full sun or partial shade. Aconitum prefers a slightly sheltered spot and benefits from regular watering during dry periods. As it grows taller, it may need light support in exposed areas.
