Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Aconitum columbianum - Nutt.

Common Name Columbian monkshood
Family Ranunculaceae
USDA hardiness Coming soon
Known Hazards The whole plant is highly toxic - simple skin contact has caused numbness in some people. The roots and seeds are the most toxic and also the leaves just before the plant flowers[212]. Available information suggests that Aconitum columbianum is probably not one of the extremely toxic aconites[270].
Habitats Moist woods to sub-alpine meadows, mostly along streams[60]. Spring-fed bogs, seep areas, meadows, along streams, and in other wet areas at elevations of 300 - 3500 metres[270].
Range North-western N. America - Alaska to California.

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Nervine  Parasiticide  Sedative

The drug 'aconite' can be obtained from the root of this plant[212]. It is used as a heart and nerve sedative[212]. This is a very poisonous plant and should only be used with extreme caution and under the supervision of a qualified practitioner.

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Special Uses

Cultivation details

Thrives in most soils and in the light shade of trees[1]. Grows well in heavy clay soils. Prefers a moist soil in sun or semi-shade[200]. Prefers a calcareous soil. Grows well in open woodlands[1, 4]. Members of this genus seem to be immune to the predations of rabbits and deer[233]. A greedy plant, inhibiting the growth of nearby species, especially legumes[54]. Closely related to A. fischeri and part of that species according to some botanists[1]. A very variable plant, there is also a sub-species (A. columbianum viviparum) that produces bulbils in the leaf axils[270].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[111]. The seed can be stratified and sown in spring but will then be slow to germinate[133]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer. Division - best done in spring but it can also be done in autumn[1, 111]. Another report says that division is best carried out in the autumn or late winter because the plants come into growth very early in the year[233]. One to several small daughter tubers are produced at the first few nodes above the parent tuber, usually below ground, in a small percentage of the plants in bulbiferous and nonbulbiferous populations[270]. These can be removed and potted up to produce new plants[K]. Bulbils are produced in the leaf axils of sub-species viviparum[270]. These are an effective means of vegetative reproduction. They fall to the ground late in the season and sprout vigorously, giving rise to new plants[270].
