Aconitum carmichaelii ‘Arendsii’

Aconitum carmichaelii ‘Arendsii’ wows with spires of deep azure blue hooded flowers in late autumn, on strong 1-1.5m spires.
So Azure Monkhood makes a stunning late season garden show, just when you think all the garden treats are over and the gloom of winter is upon us.
Aconitum also provide excellent cut flowers which last for ages in the vase.

The foliage of Azure Monkshood is also pretty, with finely divided, glossy, dark green leaves.
The leaves form a thick groundcover for the rest of the year, before the soaring flower spires impress us all in autumn.

Azure Monkshood is hardy, easy and low maintenance.
It can be planted in Sun to Part Shade.
It is extremely frost hardy, and does not require any special watering. Just normal, average garden watering is sufficient.

Azure Monkshood forms a perennial clump of foliage, low to the ground, except when in spire for the spectacular autumn flowering.
The only maintenance is to shear the spent flower spires back down to the ground in winter.
Wear gloves when dividing the plant, or cutting the flower spires, to protect yourself from the sap – all parts of plant are toxic, and should not be ingested. Fortunately it is not tempting to eat, either for rabbits, kangaroos or possums, who all leave it alone.


Seeds can be sown directly in the garden in winter or early spring / or sown in punnets indoors at any time for earlier plants.
Wear gloves when handling the seed, though there is little risk from the seed, but it is wise to treat all Aconitum with respect.

Sow in punnets on surface of good quality seed raising mix. Cover to 5cm depth with moist seed mix or vermiculite.
Moisten the mix by placing the punnet in a water bath, with the water level just below the surface, and allow the water to percolate up from the bottom. This will ensure the mix is thoroughly moist but not drenched.

Label the punnet with the name and date sown.

For best germination keep moist in a well lit position at a temperature of approx. 25C for 14 days.
Punnet can be kept moist by misting from a spray water bottle.

For best germination seeds now need a period of chilling (a pretend winter) – so wrap the sown, moist punnet in cling-wrap and place in fridge (not freezer) for 21 days.

Then take out, unwrap punnet, and keep moist in approx. 25C, in a well lit position.

Seeds need good light to sprout, but the punnet should not be in direct sunlight.
Seeds germinate in approx. 30 days.

Or sow seeds directly in garden in autumn/winter and leave to get the required chilling from winter nature before germinating in the spring.

SEED COUNT: Minimum 25 seeds per packet approximately.
(We aim to make our seed counts on the generous side – so you will receive at least 25 seeds)
