Azure Monkshood (Aconitum carmichaelii) is a striking late-season perennial known for its tall spikes of deep azure-blue to violet-blue hooded flowers. The unusual blooms resemble tiny helmets or monks' hoods, rising above handsome, deeply divided dark green foliage. Blooming in late summer to fall, this dramatic perennial brings rich color to shaded and partially shaded gardens at a time when many other perennials are beginning to fade. Its upright habit, cool blue flowers, and elegant woodland character make it a distinctive choice for perennial borders and naturalistic plantings.

Garden Uses
Azure Monkshood is excellent for shaded perennial borders, woodland gardens, cottage gardens, moist meadow edges, north-facing beds, and partially shaded foundation plantings. Its tall blue flower spikes combine beautifully with hostas, ferns, astilbe, Japanese anemones, ligularia, heuchera, ornamental grasses, cimicifuga, and late-season asters. It is especially valuable for adding vertical structure and blue color to gardens that receive morning sun or filtered afternoon shade.

Growing Information
Sow seeds in a moist, well-drained seed-starting mix and provide a period of cold stratification to improve germination. Aconitum seed can be slow and irregular, often taking several weeks or longer to sprout. Plants prefer rich, humus-filled soil that remains evenly moist but not waterlogged. Choose a site in partial shade to full sun in cooler climates, with afternoon shade preferred in hotter regions. Mature plants typically reach 36 to 48 inches tall with a spread of 18 to 24 inches. Keep soil consistently moist during dry periods and avoid disturbing established crowns once plants are settled.
