Growing it

Propagation: cuttings, division, seed
When to plant: early spring, late autumn
Overwintering: Apply a thick layer of mulch around the base to protect roots from extreme cold. Prune out any dead or damaged wood during the dormant season.
In containers: They grow well in large containers of at least 40 liters, provided they are kept well-watered.

Hardwood Cuttings

1. Take 20cm cuttings in late autumn.
2. Insert into a pot of moist, gritty compost.
3. Keep in a cold frame until spring.

Planting understory herbs like chives can help suppress weeds and provide a natural pest barrier.
