Aconitum heterophyllum

Propagation: Seed - best sown as soon as it is ripe in a cold frame[1]. The seed can be stratified and sown in spring but will then be slow to germinate[2]. 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[3][1]. 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[4].

Cultivation: Thrives in most soils and in the light shade of trees[3]. Grows well in heavy clay soils. Prefers a moist soil in sun or semi-shade[5]. Prefers a calcareous soil.

Grows well in open woodlands[3][6].

The roots of this plant are extensively collected from the wild for medicinal use and the species is becoming much rarer in many areas of its range[7].

Members of this genus seem to be immune to the predations of rabbits and deer[4].

A greedy plant, inhibiting the growth of nearby species, especially legumes[8].

Range: E. Asia - W. Himalayas.

Habitat: Usually found on humus-rich soils in the alpine and subalpine zones, and in forests, 2300 - 2900 metres[9][10].

Edibility: Leaves and root - cooked[11]. This report should be treated with great distrust due to the poisonous nature of the genus, but see the notes above on known hazards[K].

Medicinal: The dried root is analgesic, anti-inflammatory, antiperiodic, aphrodisiac, astringent, cholagogue, febrifuge and tonic[6][12]. It is used in India in the treatment of dyspepsia, diarrhoea and coughs[12][10]. It is also used in Tibetan medicine, where it is said to have a bitter taste and a cooling potency[13]. It is used to treat poisoning from scorpion or snake bites, the fevers of contagious diseases and inflammation of the intestines[13].

The root is best harvested in the autumn as soon as the plant dies down and is dried for later use[6]. This is a very poisonous plant and should only be used with extreme caution and under the supervision of a qualified practitioner.

Pollinators: Bees

Soil: Can grow in light, medium, and heavy soils.

Seed Ripens: Early Fall-Mid Fall

Heavy Clay: Grows in heavy-clay soils.

Known Hazards: The whole plant is highly toxic - simple skin contact has caused numbness in some people[3]. One report says that this plant does not contain the toxic alkaloid aconitine, and so is not poisonous[6]. It does, however, still contain an intensely bitter alk
