Growing it
- Propagation

- spring, autumn
- Overwintering
- No special winter protection is needed once established. A layer of mulch around the base helps maintain soil moisture and protects roots from extreme temperature fluctuations.
- In containers
- It is generally too large for long term container growth, though dwarf cultivars can thrive in large pots for several years.
Seed
- Scarify the hard seed coat with sandpaper.
- Soak seeds in warm water for 24 hours.
- Plant in moist soil and provide a period of cold stratification.
Plant understory perennials around the base to keep the root zone cool and moist.
