What does aconitum mean?
Aconitum is a genus of perennial flowering plants belonging to the buttercup family, Ranunculaceae. Native largely to temperate regions of the Northern Hemisphere, these plants are best known by their common names, monkshood and wolfsbane, names inspired by the distinctive helmet- or hood-shaped upper sepal that crowns each flower. The tall spires of blue, purple, or occasionally white or yellow blossoms make aconitums attractive ornamental perennials, but they carry a serious caution: all parts of the plant, especially the roots, contain potent alkaloids such as aconitine and are dangerously poisonous if ingested or absorbed through broken skin. Gardeners handle them with gloves, and herbalists once used carefully prepared extracts despite the risks. In botanical writing, aconitum appears as a formal genus name, capitalized and italicized, with numerous recognized species such as Aconitum napellus. For general readers, the word signals both striking beauty and genuine danger.
nounA genus of perennial flowering plants of the buttercup family (Ranunculaceae), commonly known as monkshood or wolfsbane, characterized by hooded blue, purple, or white flowers and highly toxic roots and foliage.
- A genus of toxic flowering plants in the buttercup family, known as monkshood or wolfsbane.
"The gardener wore gloves while handling the aconitum, mindful that every part of the plant is poisonous."
"Aconitum thrives in cool, moist borders, its deep blue spires adding drama to the late-summer garden."
"Botanists distinguish Aconitum napellus from other species of the genus by the shape of its helmeted upper sepal."
In ordinary gardening contexts the anglicized plural 'aconitums' is standard; in strict botanical writing the genus name is not pluralized.
"Several aconitums lined the shaded path, their hoods nodding in the breeze."
Every part of an aconitum plant is poisonous enough to have earned it the name 'wolfsbane' — yet gardeners still grow it for its striking hooded blooms.

Etymology of aconitum
Aconitum comes from Latin, which borrowed it from Greek akóniton, the ancient name for the poisonous plant also called wolfsbane. Classical legend tied the name to the town of Akones near the Black Sea, said to be where the plant grew abundantly, though this folk etymology is reported rather than verified. The English word entered usage through botanical Latin, and the related noun 'aconite' derives from the same Greek root.
How aconitum is actually used
A formal, chiefly botanical term; in everyday speech people are far more likely to say 'monkshood' or 'wolfsbane'. When written as a scientific genus name it is capitalized and italicized.
Easily confused with aconitum
Aconitum is the botanical genus name, while aconite refers more broadly to the plants themselves or to preparations derived from them.
