Unlike with many species from genera (and their hybrids) in Ranunculaceae (and the related Papaveroideae subfamily), there are no double-flowered forms.Ī medium to dark semi-saturated blue-purple is the typical flower color for Aconitum species. The fruit is an aggregate of follicles, a follicle being a dry, many-seeded structure. The three to five carpels are partially fused at the base. The other petals are small and scale-like or nonforming. They have a hollow spur at their apex, containing the nectar. The two upper petals are large and are placed under the hood of the calyx and are supported on long stalks. They are distinguishable by having one of the five petaloid sepals (the posterior one), called the galea, in the form of a cylindrical helmet, hence the English name monkshood. The tall, erect stem is crowned by racemes of large blue, purple, white, yellow, or pink zygomorphic flowers with numerous stamens. ĭissected flower of Aconitum vulparia, showing the nectaries Several Aconitum hybrids, such as the Arendsii form of Aconitum carmichaelii, have won gardening awards-such as the Royal Horticultural Society's Award of Garden Merit. Most Aconitum species are extremely poisonous and must be handled very carefully. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia growing in the moisture-retentive but well-draining soils of mountain meadows. Aconitum subgenus Lycoctonum ( DC.)
