Growing:
Soak your seeds for 24 hours. Place into semi-moist peat moss or sand and place into fridge to cold stratify for 90 days. After the cold treatment, spread seeds over the surface of the growing medium and press down lightly. The seeds need light exposure in order to germinate. Place in a bright, humid spot at about 15 to 18 °C. The seeds will germinate after 2 to 4 weeks. After another four weeks, separate and pot the young plants. Plant outside once the risk of frost has past. Prune back old, harvested, and dry canes close to the ground every autumn.
This plant is designated as an invasive species in some areas.
