Southern blue monkshood

Description

Aconitum uncinatum, commonly known as wild monkshood or southern blue monkshood, is a species of flowering plant in the buttercup family, Ranunculaceae. It grows in moist to wet habitats along streams and in woods and clearings. It grows in the eastern United States in the Appalachian Mountains, on the Piedmont, and on the upper Atlantic Coastal Plain. Aconitum also known as aconite, monkshood, wolf's-bane, leopard's bane, mousebane, women's bane, devil's helmet, queen of poisons, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. 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. Most Aconitum species are extremely poisonous and must be handled very carefully. 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.Some are used by florists. The dark green leaves of Aconitum species lack stipules. They are palmate or deeply palmately lobed with five to seven segments. Each segment again is trilobed with coarse sharp teeth. The leaves have a spiral (alternate) arrangement. The lower leaves have long petioles. Dissected flower of Aconitum vulparia, showing the nectaries. The tall, erect stem is crowned by racemes of large blue, purple, white, yellow, or pink zygomorphic flowers with numerous stamens. 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. Two to 10 petals are present. The two upper petals are large and are placed under the hood of the calyx and are supported on long stalks. They have a hollow spur at their apex, containing the nectar. The other petals are small and scale-like or nonforming. The three to five carpels are partially fused at the base. The fruit is an aggregate of follicles, a follicle being a dry, many-seeded structure. Unlike with many species from genera (and their hybrids) in Ranunculaceae (and the related Papaveroideae subfamily), there are no double-flowered forms.
