Aconitum napellus

monkshood

• Position: sun to partial shade
• Soil: moist, fertile
• Rate of Growth: average
• Flowering period: July to August
• Hardiness: fully hardy
  
  This stately monkshood produces erect spikes of hooded,violet-blue flowers in mid and late summer above deeply divided, dark green leaves. Although it will take some sun, it is perfect for the back of a shady border, where it needs little attention. The stems seldom need staking and, since all parts of the plant are highly poisonous, pests tend to leave them well alone.
  
  
• Garden care: Prepare an extra deep planting hole at least 45cm (18in) deep, adding well-rotted organic matter to prevent the soil from drying out in summer. Always wear gloves when working with monkshood since all parts of the plant are poisonous and a potential skin irritant.
