Aconitum violaceum

Aconitum violaceum belongs to the buttercup family, Ranunculaceae. It is a perennial, so it lives for more than one year. Its native range runs from northern Pakistan to central Nepal. It grows in temperate regions, but is not native to Britain or Ireland. Wild plants grow among shrubs and on open slopes. These sites lie at 11,800–15,750 feet [3,600–4,800 metres] above sea level. Kew lists it as a perennial or tuberous geophyte. This means it may live on through an underground storage organ.

Plants For A Future says this species varies in form. The sources give no firm height or spread for mature plants. They give no leaf or stem details for this species. It blooms from August through October. Bees pollinate its flowers, carrying pollen between them. The evidence gives no flower colour or fruit details for this species. The RHS gives flower and leaf traits for the genus alone. These do not show which traits this species has.

Plants For A Future lists sun and light shade as suitable. It says the plant prefers moist soil. It lists sand, loam and clay, even heavy clay. Soil may be mildly acid, neutral or mildly alkaline. It suggests a woodland garden with patches of light and shade. The source gives USDA zones 5–9. Yet it casts doubt on how well plants withstand British cold. Its detailed growing notes draw on the needs of the genus. Use those wider notes as a guide. They are not tested results for this species.

The notes on raising plants favour fresh seed in a cold frame. Stored seed may need stratification, a cold spell, before spring sowing. Seeds can then be slow to sprout. Give each young seedling its own pot once large enough to handle. Keep them in a cold frame through their first winter. Plant them out in late spring or early summer. The source also lists division: splitting plants to make more. The reports it cites differ on the best season for this.

Safety is a key concern with this plant. Plants For A Future warns that all parts are highly poisonous. It reports that skin contact makes some people feel numb. Reports of cooked roots as food clash with that warning. Do not read them as proof of safe use. The source records whole-plant use in Tibetan medicine. These past uses do not prove safety or show that treatments work.
