Blooming later than most Aconitum species, award-winning Aconitum carmichaelii 'Arendsii'(Monkshood) is an erect, tuberous perennial with dense spires of rich azure-blue flowers in early to mid fall. Its hooded flowers resemble the hood worn by medieval monks, hence the common names of monkshood. They are borne atop thick, rigid stems clad with a handsome foliage of deeply divided, leathery, dark green leaves. This fall-flowering makes outstanding cut flowers and is perfect for wet soils.
