Aconitum 'Henry I Sparks Variety' (Monkshood)

Aconitum 'Henry I Sparks Variety,' commonly known as Monkshood, is an upright, clump-forming perennial known for its striking spikes of deep violet-blue, hooded flowers that resemble a monk's cowl. These blooms rise above deeply lobed, glossy dark green foliage, creating an elegant and dramatic effect in the garden. Monkshood is a classic choice for adding vertical interest to borders or shaded areas.

Aconitum 'Henry I Sparks Variety' thrives in rich, well-drained soils with consistent moisture, making it suitable for borders, woodland gardens, or cottage garden settings. It is deer- and rabbit-resistant, and its flowers are highly attractive to pollinators such as bees and butterflies. However, care should be taken as all parts of the plant are toxic if ingested, and gloves should be worn when handling it. This low-maintenance perennial pairs beautifully with other shade-tolerant plants like astilbes, hostas, or ferns for a lush and textured garden display. Deadheading spent blooms can help maintain a tidy appearance and encourage fresh growth.
