Monkshood (Aconitum) is best known for its dense spikes of pretty, purple-blue "hooded" flowers that bloom atop 2-4' tall plants. The ferny foliage is attractive and provides a nice textural component. From a distance, Monkshood looks like Delphinium and provides a similar vertical accent in the garden. It blooms for weeks from mid to late summer and makes a great companion plant to Purple Coneflowers, Sedum 'Autumn Joy' and New England Asters.
Does best in full sun and moist soil, but will tolerate part shade. May need to be staked in part shade. Deer, rodent and rabbit resistant! Easy to grow, hardy and long-lived, Monkshood resents being disturbed and may take a year after planting to look its best.
