Aconitum
Monkshood / Wolf's Bane
RANUNCULACEAE

Herbaceous Perennial
Poisonous and not suitable for the Garden if you have Children.
Even contact with the foliage can cause allergic reactions.

 

Monkshood gained their name because of their tall spires of hooded flowers, which come in shades of white, pale yellow, lilac, or blue. The flower spikes being held above dense clumps of divided green foliage. 

The flowers appearing from early summer to autumn, depending upon the variety, attract butterflies, bees and other beneficial insects into the garden



Cultivation: -

Aconitums should be grown in cool, reasonably fertile, moist soil, preferably in partial shade, where they will spread and increase in size. But most soils will be tolerated, as will full sun, provided that the soil is damp enough.

Taller Aconitums should be provided with support to prevent them being knocked down by the wind or rain.

At the end of the growing season cut down the current years growth.

Every few years established clumps should be divided to maintain vigour 

 

Propagation: -

Sow seed in pots or the cold frame during spring, or divide established clumps during late autumn or winter.

When splitting clumps remember that all parts of these plants are poisonous.
