Dangers connus

• The whole plant is highly toxic - simple skin contact has caused numbness in some people [1, 13, 65, 200].

Comestibilité

• Feuilles - cuites [178].
• This species is supposed to be non-toxic[178], but this report should be treated with some scepticism due to the highly toxic nature of the genus in general [K].

Culture

• Thrives in most soils and in the light shade of trees [1].
• Pousse bien dans les sols très argileux .
• 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. napellus [1].

Propagation

• Graine - le mieux est de semer dès qu'elles sont mûres sous un chassis [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 .
• Plantez les en extérieur à la fin du printemps ou au début de l'été .
• 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].
